+ ### What happened?
+ Secret scanning detected potential secrets or API keys in a commit to the main branch.
+ The commit has been automatically reverted to prevent exposure.
+
+ ### Required Actions:
+
+ 1. **β οΈ ROTATE ALL EXPOSED SECRETS IMMEDIATELY**
+ - If the secret was an API key, revoke it
+ - If it was an AWS key, disable it in IAM
+ - Generate new credentials
+
+ 2. **Clean up your local branch**:
+ \`\`\`bash
+ git fetch origin
+ git reset --hard origin/main
+ \`\`\`
+
+ 3. **Remove the secret properly**:
+ - Use environment variables
+ - Use GitHub Secrets
+ - Use AWS Secrets Manager / Parameter Store
+ - Add pattern to .gitignore
+
+ 4. **Re-commit without secrets**:
+ - Make your changes again
+ - Ensure no secrets are in the code
+ - Submit a new PR
+
+ ### Preventing Future Incidents:
+
+ - Always use \`.tfvars\` files for sensitive values (they're gitignored)
+ - Use \`backend.tf\` for backend config (also gitignored)
+ - Store secrets in GitHub Secrets or AWS Secrets Manager
+ - Run \`git diff\` before committing to review changes
+ - Enable pre-commit hooks for local secret scanning
+

+# GitHub App Setup for Coder
+
+## Correct Callback URLs
+
+When configuring your GitHub App for Coder, use these **exact** callback URLs:
+
+### Primary OAuth (User Authentication)
+
+```
+https://coderdemo.io/api/v2/users/oauth2/github/callback
+```
+
+### External Auth (Git Operations in Workspaces)
+
+```
+https://coderdemo.io/api/v2/external-auth/primary-github/callback
+```
+
+## Important Settings
+
+1. **Request user authorization (OAuth) during installation**: β
**MUST be checked**
+ - This allows users to log into Coder with their GitHub identity
+
+2. **Permissions Required**:
+ - **Account permissions**:
+ - Email addresses: Read-only
+ - **Repository permissions**:
+ - Contents: Read and write
+ - Metadata: Read-only (auto-required)
+ - Pull requests: Read and write (optional, for PR creation)
+ - Issues: Read and write (optional, for issue management)
+
+3. **Installation**:
+ - Install the app to your account/organization
+ - Grant access to "All repositories" or specific repos
+
+## Common Issues
+
+### "redirect_uri is not associated with this application"
+
+- **Cause**: Callback URLs don't match what Coder is sending
+- **Solution**: Verify the URLs above are **exactly** correct (including `/api/v2/users/` and `/api/v2/`)
+
+### "Not HTTPS Secure" warning
+
+- **Cause**: Accessing `http://coderdemo.io` instead of `https://coderdemo.io`
+- **Solution**: Always use `https://` when accessing Coder
+
+## After Setup
+
+Once configured, users can:
+
+- Log into Coder using GitHub authentication
+- Clone repositories in their workspaces
+- Push/pull code
+- Create pull requests (if permissions granted)

## How-To-Deploy
-> [!WARNING] The following environment is heavily opinionated towards: AWS. Make sure to pull the modules and modify according to your use-case. Additionally, the [`infra/aws/us-east-2`](./infra/aws/us-east-2) project is not repeatable. For repeatable references, check out [`infra/aws/us-west-2`](./infra/aws/us-west-2) and [`infra/aws/eu-west-2`](./infra/aws/eu-west-2)
+> [!WARNING]
+> **Infrastructure Repeatability Notice**
+>
+> This environment is heavily opinionated towards AWS and uses a hub-and-spoke architecture:
+>
+> - **[`infra/aws/us-east-2`](./infra/aws/us-east-2)** - Primary hub region with foundational infrastructure (database, terraform backend, VPC, etc.). **This is NOT repeatable** - it's meant to be deployed once as your control plane.
+> - **[`infra/aws/eu-west-2`](./infra/aws/eu-west-2)** - Clean spoke region example with workspace proxy only. **This IS repeatable** for adding new regions.
+> - **[`infra/aws/us-west-2`](./infra/aws/us-west-2)** - Hybrid spoke region with both server and proxy deployments. Use this as a reference for redundant server deployments.
+>
+> When deploying to new regions, use `eu-west-2` as your template for workspace proxies.
+
+### Deployment Overview
+
+The infrastructure is deployed in layers:
+
+1. **Foundation Layer** (us-east-2 only - deploy once)
+ - Terraform backend (S3 + DynamoDB)
+ - VPC with custom networking
+ - Aurora Serverless v2 PostgreSQL database
+ - ECR for container images
+ - Redis for caching
+
+2. **Compute Layer** (all regions)
+ - EKS clusters with managed node groups
+ - Karpenter for workspace autoscaling
+ - VPC peering (for spoke regions to hub)
+
+3. **Certificate & DNS Layer** (all regions)
+ - AWS Certificate Manager (ACM) for SSL/TLS
+ - Route53 for DNS management
+ - Regional subdomains (e.g., `us-west-2.coderdemo.io`)
+
+4. **Kubernetes Applications Layer** (all regions)
+ - AWS Load Balancer Controller
+ - AWS EBS CSI Driver
+ - Karpenter node provisioner
+ - Metrics Server
+ - Cert Manager
+
+5. **Coder Layer**
+ - **Primary (us-east-2)**: Coder Server with database connection
+ - **Spoke regions**: Coder Workspace Proxies connected to primary
+
+### About the Infrastructure Modules
+
+This repository provides reusable Terraform modules for deploying Coder on AWS:
+
+#### Network Module: [`eks-vpc`](./modules/network/eks-vpc)
+
+Creates an opinionated VPC designed for EKS and Coder workloads:
+
+- Customizable public and private subnets across multiple AZs
+- Internet Gateway for public access
+- Cost-optimized NAT Gateway using [fck-nat](https://github.com/RaJiska/terraform-aws-fck-nat)
+- Automatic routing configuration
+- Subnet tagging for EKS and Karpenter integration
+
+#### Compute Module: [`eks-cluster`](./modules/compute/cluster)
+
+Creates a production-ready EKS cluster similar to [EKS Auto Mode](https://docs.aws.amazon.com/eks/latest/userguide/automode.html):
+
+- Leverages the [AWS Managed Terraform EKS module](https://github.com/terraform-aws-modules/terraform-aws-eks/tree/master)
+- Pre-configured IAM roles and policies for:
+ - [Karpenter](https://karpenter.sh/) - Node autoscaling

+
+#### Kubernetes Bootstrap Modules: [`modules/k8s/bootstrap/`](./modules/k8s/bootstrap/)
+
+Helm-based Kubernetes application deployments:
+
+- **[`lb-controller`](./modules/k8s/bootstrap/lb-controller)** - AWS Load Balancer Controller
+- **[`ebs-controller`](./modules/k8s/bootstrap/ebs-controller)** - AWS EBS CSI Driver
+- **[`metrics-server`](./modules/k8s/bootstrap/metrics-server)** - Kubernetes Metrics Server
+- **[`karpenter`](./modules/k8s/bootstrap/karpenter)** - Karpenter autoscaler with NodePools

+
+---
+
+## Deployment Guide
+
+### Prerequisites
+
+- AWS CLI configured with appropriate credentials
+- Terraform >= 1.9.0
+- kubectl
+- Helm 3.x
+- GitHub OAuth App credentials (for authentication)
+
+### Step 1: Deploy Foundation Infrastructure (us-east-2 only)
+
+> [!IMPORTANT]
+> Only deploy this once for your entire multi-region setup.
+
+```bash
+cd infra/aws/us-east-2
+
+# 1. Create Terraform backend
+cd terraform-backend
+terraform init
+terraform apply
+cd ..
+
+# 2. Create VPC
+cd vpc
+terraform init -backend-config=backend.hcl
+terraform apply
+cd ..
+
+# 3. Deploy EKS cluster
+cd eks
+terraform init -backend-config=backend.hcl
+terraform apply
+cd ..
+
+# 4. Deploy Aurora Serverless v2 database
+cd rds
+terraform init -backend-config=backend.hcl
+terraform apply
+cd ..
+
+# 5. Set up Route53 and ACM for primary domain
+cd route53
+terraform init -backend-config=backend.hcl
+terraform apply
+cd ..
+
+cd acm
+terraform init -backend-config=backend.hcl
+terraform apply
+cd ..
+```
+
+### Step 2: Deploy Kubernetes Applications (us-east-2)
-In this repository, we deploy the infrastructure separately from the K8s applications which includes Coder.
+```bash
+cd infra/aws/us-east-2/k8s
-To make things easy, we generate K8s app manifests from any `k8s/` project subfolders which reference the main `eks/` application indirectly which auto-populates any infrastructure dependent resource names.
+# Update kubeconfig
+aws eks update-kubeconfig --region us-east-2 --name coderdemo
-### About the Infrastructure
+# Deploy in order (each depends on previous)
+cd lb-controller && terraform init -backend-config=backend.hcl && terraform apply && cd ..
+cd ebs-controller && terraform init -backend-config=backend.hcl && terraform apply && cd ..
+cd metrics-server && terraform init -backend-config=backend.hcl && terraform apply && cd ..
+cd karpenter && terraform init -backend-config=backend.hcl && terraform apply && cd ..
+cd cert-manager && terraform init -backend-config=backend.hcl && terraform apply && cd ..
-The deployment currently has 2 repeatable components: [`eks-vpc` module](./modules/network/eks-vpc) and [`eks-cluster` module](./modules/compute/cluster).
+# Deploy Coder Server
+cd coder-server && terraform init -backend-config=backend.hcl && terraform apply && cd ..
-#### [`eks-vpc`](./modules/network/eks-vpc)
+# Deploy Coder Workspace Provisioner
+cd coder-ws && terraform init -backend-config=backend.hcl && terraform apply && cd ..
+```
-The following module creates an opinionated VPC that let's you granularly define individual subnets. This includes unevenly defining public and private subnets.
+### Step 3: Deploy Spoke Regions (repeatable)
-This will come with an Internet Gateway and a Custom NAT Gateway (using [RaJiska/terraform-aws-fck-nat](github.com/RaJiska/terraform-aws-fck-nat)).
+For each additional region (use `eu-west-2` as template):
-The public subnets will have automatic routes to the IGW and private subnets with routes to the NAT.
+```bash
+# Example: Deploy to eu-west-2
+cd infra/aws/eu-west-2
-#### [`eks-cluster`](./modules/compute/cluster).
+# 1. Deploy EKS cluster
+cd eks
+terraform init -backend-config=backend.hcl
+terraform apply
+cd ..
-The following module creates an opinionated cluster, similar to [EKS Auto Mode](https://docs.aws.amazon.com/eks/latest/userguide/automode.html), that creates both the EKS Cluster (using the [AWS Managed Terraform EKS module](https://github.com/terraform-aws-modules/terraform-aws-eks/tree/master)), and resources needed by:
+# 2. Deploy Kubernetes applications (same order as us-east-2)
+cd k8s
+aws eks update-kubeconfig --region eu-west-2 --name coderdemo-euw2
-- [Karpenter](https://karpenter.sh/)
-- [Amazon Bedrock](https://docs.aws.amazon.com/bedrock/latest/userguide/what-is-bedrock.html)
-- [AWS EBS Controller](https://github.com/kubernetes-sigs/aws-ebs-csi-driver)
-- [AWS Load Balancer Controller](https://github.com/kubernetes-sigs/aws-load-balancer-controller)
-- [Coder External Provisioner](https://coder.com/docs/admin/provisioners)
+cd lb-controller && terraform init -backend-config=backend.hcl && terraform apply && cd ..
+cd ebs-controller && terraform init -backend-config=backend.hcl && terraform apply && cd ..
+cd metrics-server && terraform init -backend-config=backend.hcl && terraform apply && cd ..
+cd karpenter && terraform init -backend-config=backend.hcl && terraform apply && cd ..
+cd cert-manager && terraform init -backend-config=backend.hcl && terraform apply && cd ..
-##### Karpenter
+# 3. Deploy Coder Workspace Proxy
+cd coder-proxy && terraform init -backend-config=backend.hcl && terraform apply && cd ..
+
+# 4. Deploy Coder Workspace Provisioner
+cd coder-ws && terraform init -backend-config=backend.hcl && terraform apply && cd ..
+```
-We use the the [AWS Managed Terraform EKS Module for Karpenter in the background](https://github.com/terraform-aws-modules/terraform-aws-eks/tree/master/modules/karpenter).
+### Step 4: Configure DNS and Certificates
-This automatically creates:
-- SQS Queue
-- IAM Roles
-- Event Bridge
+Each region requires:
-##### Amazon Bedrock
+1. Route53 DNS records pointing to the regional load balancer
+2. ACM certificate for the regional subdomain
+3. TLS certificate configuration in Coder proxy/server
-Auto-Creates
-- IAM Role
+See the region-specific configurations in:
-##### AWS EBS Controller
+- `infra/aws/us-east-2/route53/`
+- `infra/aws/us-west-2/route53/`
+- `infra/aws/us-west-2/acm/`

+Each deployment requires a `terraform.tfvars` file (gitignored for security). Key variables include:
-##### Coder External Provisioner
+#### EKS Variables
-Auto-Creates
-- IAM Role
+```hcl
+cluster_name = "coderdemo"
+cluster_region = "us-east-2"
+cluster_profile = "your-aws-profile"
+```
+#### Coder Variables
-### Creating the Infrastructure (on AWS)
+```hcl
+coder_access_url = "https://coderdemo.io"
+coder_wildcard_access_url = "*.coderdemo.io"
+addon_version = "2.27.1" # Coder version
+```
-To deploy the base infrastructure, you can get started with referencing our [modules directory](./modules).
+#### Database (us-east-2 only)
-If you don't have an existing network infrastructure, then you can start with deploying the [`eks-vpc` module](./modules/network/eks-vpc).
+```hcl
+coder_db_secret_url = "postgres://user:pass@host:5432/coder?sslmode=require"
+```
-Additionally, if you don't have an existing cluster infrastructure, then you can start with deploying the [`eks-cluster` module](./modules/compute/cluster).
+#### Authentication
-Lastly, for Coder's backend database, you can refer to our deployment in [`./aidev/infra/aws/us-east-2/rds`](./aidev/infra/aws/us-east-2/rds) to see how to deploy it.
+```hcl
+# GitHub OAuth
+coder_oauth_secret_client_id = "your-github-oauth-client-id"
+coder_oauth_secret_client_secret = "your-github-oauth-secret"
-We just an [`aws_db_instance`](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/db_instance) that uses Postgres.
+# GitHub External Auth (for workspace git operations)
+coder_github_external_auth_secret_client_id = "your-github-app-id"

-The deployment may take a while (~20 minutes or more). In the meantime, you can then get started with creating other dependencies.

+
+## Multi-Region Architecture Details
+
+### Database Strategy
+
+This deployment uses a **centralized database** approach:
+
+- Aurora Serverless v2 PostgreSQL in us-east-2
+- All regions connect to the same database over VPC peering
+- Benefits: Simplified data consistency, no replication complexity
+- Trade-offs: All regions depend on us-east-2 availability
+
+For production high-availability requirements, consider:
+
+- Aurora Global Database for multi-region read replicas
+- Active-active deployments with database replication
+- Regional database failover strategies
+
+See [Multi-Region Deployment Guide](./docs/MULTI_REGION_DEPLOYMENT.md) for more details.
+
+### Workspace Proxy Strategy
+
+Workspace proxies provide:
+
+- **Low-latency connections** to workspaces in remote regions
+- **Reduced bandwidth costs** by keeping traffic regional
+- **Improved user experience** for global teams
+
+Each proxy:
+
+1. Registers with the primary Coder server (us-east-2)
+2. Receives a session token for authentication
+3. Proxies workspace connections without database access
+4. Can run workspace provisioners locally
+
+### Network Architecture
+
+- **VPC Peering**: Spoke regions peer with hub region for database access
+- **NAT Strategy**: Cost-optimized fck-nat for outbound internet access
+- **Load Balancers**: NLB for Coder, ALB for other services
+- **DNS**: Regional subdomains route to closest workspace proxy
-### Deploying Required Apps
+---
+
+## Monitoring and Observability
+
+> [!NOTE]
+> Observability stack configuration is in progress.
+
+Planned integrations:
+
+- Prometheus for metrics collection
+- Grafana for visualization
+- CloudWatch for AWS resource monitoring
+- Coder built-in metrics and health endpoints
+
+---
+
+## Security Considerations
+
+### Secrets Management
+
+- **Database credentials**: Stored in terraform.tfvars (gitignored)
+- **OAuth credentials**: Stored in terraform.tfvars (gitignored)
+- **TLS certificates**: Managed by AWS ACM
+- **Kubernetes secrets**: Created by Terraform, stored in etcd
+
+For production, consider:
+
+- AWS Secrets Manager for credential rotation
+- External Secrets Operator for Kubernetes
+- HashiCorp Vault for centralized secret management
+
+### Network Security
+
+- Private subnets for all compute resources
+- Security groups restricting traffic between tiers
+- VPC peering for controlled cross-region access
+- TLS encryption for all external endpoints
+
+### IAM Best Practices
+
+- IRSA (IAM Roles for Service Accounts) for pod-level permissions
+- Least privilege principle for all IAM policies
+- No long-lived credentials in pods
+- Regular IAM policy audits
+
+---
+
+## Cost Optimization
+
+Key strategies used in this deployment:
+
+1. **Karpenter Autoscaling**: Scales nodes to zero when workspaces are idle
+2. **Aurora Serverless v2**: Scales database capacity based on load
+3. **fck-nat**: Open-source NAT solution (90% cheaper than AWS NAT Gateway)
+4. **Spot Instances**: Karpenter uses spot for workspace nodes where appropriate
+5. **Regional Resources**: Only deploy proxies in regions with active users
-Once the K8s (and maybe the Database) infrastructure is deployed, the next step is to deploy the K8s apps.
+Estimated monthly costs:
-Before getting to Coder, we should first deploy:
+- Hub region (us-east-2): $200-400/month base + per-workspace costs
+- Spoke regions: $100-200/month base + per-workspace costs
-- [`AWS Load Balancer Controller`](https://github.com/kubernetes-sigs/aws-load-balancer-controller)
-- [`AWS EBS Controller`](https://github.com/kubernetes-sigs/aws-ebs-csi-driver)
-- [`K8s Metrics Server`](github.com/kubernetes-sigs/metrics-server)
-- [`Karpenter`](https://karpenter.sh/docs/getting-started/getting-started-with-karpenter/#4-install-karpenter)
-- [`Cert-Manager`](https://cert-manager.io/docs/installation/helm/)
+See [Infrastructure Best Practices](./docs/INFRASTRUCTURE_BEST_PRACTICES.md) for detailed cost analysis.
-Afterwards, you can then deploy
+---
+
+## Troubleshooting
+
+### Common Issues
+
+**EKS cluster creation fails**
+
+- Verify IAM permissions for EKS and VPC operations
+- Check VPC CIDR doesn't conflict with existing networks
+- Ensure sufficient EIPs available in the region
+
+**Karpenter not scaling nodes**
-- [`Coder Server`](https://artifacthub.io/packages/helm/coder-v2/coder)
-- [`Coder Proxy` (uses same chart as the Coder Server)](https://artifacthub.io/packages/helm/coder-v2/coder)
-- [`Coder Workspace`](https://artifacthub.io/packages/helm/coder-v2/coder-provisioner)
+- Verify Karpenter controller has IRSA permissions
+- Check NodePool configurations in `k8s/karpenter/`
+- Review Karpenter logs: `kubectl logs -n karpenter -l app.kubernetes.io/name=karpenter`
-You can deploy the above manually yourself following your own preferred methods.
+**Coder proxy not connecting**
-Otherwise, you can leverage our K8s app TF modules to automatically generate the manifests:
+- Verify proxy token is correctly configured
+- Check network connectivity from proxy to primary server
+- Review NLB health checks and target group status
-#### [`lb-controller`](./modules/k8s/apps/lb-controller)
+**Database connection failures**
-#### [`ebs-controller`](./modules/k8s/apps/ebs-controller)
+- Verify security group allows traffic from EKS nodes
+- Check VPC peering routes are configured
+- Confirm database URL includes `?sslmode=require`
-#### [`metrics-server`](./modules/k8s/apps/metrics-server)
+### Useful Commands
-#### [`karpenter`](./modules/k8s/apps/karpenter)
+```bash
+# Check EKS cluster status
+aws eks describe-cluster --name coderdemo --region us-east-2
-#### [`cert-manager`](./modules/k8s/apps/cert-manager)
+# Get kubeconfig
+aws eks update-kubeconfig --name coderdemo --region us-east-2
-#### [`coder-server`](./modules/k8s/apps/coder-server)
+# View Karpenter logs
+kubectl logs -n karpenter -l app.kubernetes.io/name=karpenter -f
-#### [`coder-proxy`](./modules/k8s/apps/coder-proxy)
+# Check Coder server logs
+kubectl logs -n coder -l app.kubernetes.io/name=coder -f
+
+# List all Karpenter nodes
+kubectl get nodes -l karpenter.sh/initialized=true
+
+# Check workspace proxy status
+kubectl get pods -n coder-proxy
+```

+
+## Key Architecture Decisions
+
+### 1. Network Load Balancer (NLB) over Application Load Balancer (ALB)
+
+**Why NLB:**
+
+- **Lower latency:** Layer 4 (TCP) vs Layer 7 (HTTP)
+- **Source IP preservation:** Essential for Coder audit logs
+- **Static IPs:** Easier for enterprise firewall rules
+- **Long-lived connections:** Better for WebSocket connections (terminals, live updates)
+- **Cost efficiency:** Lower cost at high volume
+
+**TLS Termination at NLB:**
+
+- NLBs DO support TLS termination when configured with ACM certificates
+- Configured via AWS Load Balancer Controller service annotations
+- Traffic flow: User (HTTPS:443) β NLB (terminates TLS) β Coder (HTTP:8080)
+
+### 2. Multi-Region with Latency-Based Routing
+
+**Benefits:**
+
+- **Automatic performance optimization:** Users connect to nearest region
+- **Built-in failover:** Route53 health checks automatically remove unhealthy regions
+- **Manual override available:** Region-specific URLs for demos and testing
+- **Global reach:** Serves users worldwide with low latency
+
+**Implementation:**
+
+- Route53 latency routing policy
+- Health checks per region
+- Shared RDS database across regions (for unified accounts)
+
+### 3. Cost Optimizations
+
+**Implemented:**
+
+- **Graviton ARM instances:** t4g.xlarge (lower cost than x86)
+- **VPC Endpoints:** S3, ECR API/DKR (reduces NAT Gateway costs)
+- **fck-nat:** Custom NAT solution instead of AWS NAT Gateway
+- **Karpenter:** Right-sized workspace nodes, automatic termination
+- **gp3 volumes:** Better performance than gp2 at same cost
+- **Spot instances:** For workspace nodes (when interruption-tolerant)
+
+### 4. Security Best Practices
+
+**IRSA (IAM Roles for Service Accounts):**
+
+- No AWS credentials stored in Kubernetes secrets
+- Least-privilege access per service
+- Automatic credential rotation
+
+**Network Segmentation:**
+
+- Separate subnets for system, provisioner, and workspaces
+- RDS in private subnet with no public access
+- Security groups restrict traffic by source/destination
+
+**TLS Everywhere:**
+
+- ACM certificates with auto-renewal
+- TLS termination at load balancer
+- Secure cookies enabled
+
+### 5. Helm Chart Management
+
+**Decision: `upgrade_install = true`**
+
+- Idempotent Terraform applies
+- No "already exists" errors in CI/CD
+- Declarative version management
+- Re-added in Helm provider version 3.1.1
+
+### 6. Aurora Serverless v2 for Cost Optimization
+
+**Configuration:**
+
+- Engine: Aurora PostgreSQL 15.8 (Serverless v2)
+- Scaling: 0.5-16 ACU for Coder, 0.5-8 ACU for LiteLLM
+- Multi-AZ: Writer + Reader instances
+
+**Benefits:**
+
+- **Cost savings:** Scales down to 0.5 ACU (~$9/month) during idle periods
+- **Auto-scaling:** Automatically scales up to handle load (up to 16 ACU = 32 GB RAM)
+- **No manual intervention:** Seamless scaling based on demand
+- **Pay-per-use:** Only pay for ACU-hours consumed vs 24/7 provisioned instance
+
+**Trade-off:**
+
+- **Cold start delay:** 5-10 second initial response after idle period (>30 minutes)
+- **Acceptable for demo environment** where cost optimization outweighs instant response
+
+---
+
+## Known Behaviors (Demo Environment)
+
+This section documents expected behaviors in the demo environment that optimize for cost over instant response time.
+
+### 1. Aurora Serverless v2 Cold Start (5-10 seconds)
+
+**When it happens:**
+
+- After 30+ minutes of no database activity
+- First visitor after idle period
+
+**What you'll see:**
+
+- Site takes 5-10 seconds to load initially
+- Subsequent requests are instant (<100ms)
+- Aurora scales from 0.5 ACU β 1-2 ACU automatically
+
+**Why it's acceptable:**
+
+- Demo environment prioritizes cost savings
+- Saves ~$120/month vs provisioned RDS
+- No errors, just slower initial load
+- Perfect for sporadic demo usage
+
+**To eliminate (if needed):**
+
+- Increase `min_capacity = 2` in `infra/aws/us-east-2/rds/main.tf`
+- Trade-off: ~$35/month baseline vs $9/month
+
+### 2. HTTPβHTTPS Redirect Delay ("Not Secure" Warning)
+
+**When it happens:**
+
+- User types `coderdemo.io` without `https://`
+- Browser tries HTTP:80 first (standard behavior)
+
+**What you'll see:**
+
+1. Browser shows "Connecting..." or spinning
+2. Brief "Site is not secure" warning (2-3 seconds)
+3. Warning disappears, site loads normally with HTTPS
+
+**Root cause:**
+
+- NLB only has port 443 (HTTPS) listener configured
+- No port 80 (HTTP) listener to redirect to HTTPS
+- NLBs don't support HTTPβHTTPS redirects (ALB feature only)
+- Browser timeout on port 80, then retries port 443
+
+**Why it's acceptable:**
+
+- Demo environment, not production
+- Site works perfectly once HTTPS connects
+- No security risk (just UX delay)
+- Users who bookmark or click links use HTTPS directly
+
+**Why HSTS is NOT configured:**
+
+HSTS (HTTP Strict Transport Security) headers would help eliminate the "not secure" warning by making browsers automatically use HTTPS after the first visit. However, **Coder's HSTS feature does not work when behind a reverse proxy.**
+
+**Investigation findings:**
+
+- Coder supports HSTS via `CODER_STRICT_TRANSPORT_SECURITY` environment variable
+- However, Coder only sends HSTS headers when it directly terminates TLS (`CODER_TLS_ENABLE=true`)
+- When behind an NLB/reverse proxy with `CODER_TLS_ENABLE=false`, Coder sees incoming HTTP traffic
+- Coder's help states: "This header should only be set if the server is accessed via HTTPS"
+- Since Coder doesn't detect it's behind an HTTPS proxy, it won't send HSTS headers
+
+**Workaround not possible without:**
+
+- Switching to ALB (which can do HTTPβHTTPS redirect at load balancer level)
+- Having Coder terminate TLS directly (loses NLB benefits)
+- Waiting for Coder to add reverse-proxy awareness for HSTS feature
+- Using CloudFront in front of NLB for HTTPβHTTPS redirect
+
+**Alternative mitigation options:**
+
+- Option A: Add CloudFront with HTTPβHTTPS redirect (adds complexity and cost)
+- Option B: Switch to ALB (loses NLB benefits: lower latency, source IP preservation)
+- Option C: Configure port 80 forwarding in Coder service (complex, not standard)
+- Option D: Accept current behavior (recommended for demo environment)
+
+### Summary of Expected Load Times
+
+| Scenario | Load Time | Behavior |
+| ------------------------- | --------------- | -------------------------------------------------- |
+| **First visit (HTTP)** | 7-13 seconds | HTTP:80 timeout (2-3s) + Aurora cold start (5-10s) |
+| **First visit (HTTPS)** | 5-10 seconds | Aurora cold start only |
+| **Return visit (HTTP)** | 7-13 seconds | HTTP:80 timeout (2-3s) + Aurora cold start (5-10s) |
+| **After warm-up (HTTPS)** | <100ms | Instant, everything cached |
+| **Bookmarked/HTTPS link** | <100ms or 5-10s | Instant if warm, cold start if idle |
+
+**Note:** Always share URLs as `https://coderdemo.io` to avoid the 2-3 second HTTP:80 timeout delay.

+## Load Balancer Architecture
+
+### Decision: Network Load Balancer (NLB) with TLS Termination
+
+**What We Did:**
+
+- Deployed NLB with TLS termination using ACM certificates
+- Configured `CODER_TLS_ENABLE = "false"` on Coder server
+- NLB terminates TLS and forwards plain HTTP to backend
+
+**Why This Approach:**
+
+#### NLB Advantages for Coder
+
+1. **Lower Latency** - Layer 4 (TCP) vs Layer 7 (HTTP)
+ - Less protocol overhead
+ - Direct connection forwarding
+ - Critical for long-lived WebSocket connections (terminals, live updates)
+
+2. **Source IP Preservation**
+ - NLB preserves client source IP addresses
+ - Essential for Coder's audit logs and security monitoring
+ - No need to parse `X-Forwarded-For` headers
+
+3. **Static IP Addresses**
+ - NLB provides static IPs per availability zone
+ - Easier for enterprise firewall rules and allowlists
+ - ALB uses dynamic IPs (requires DNS-based allowlisting)
+
+4. **Connection Handling**
+ - Better for long-lived persistent connections
+ - Coder workspaces maintain extended connections
+ - Lower overhead per connection
+
+5. **Cost Efficiency**
+ - NLB: $0.0225/hour + $0.006/GB processed
+ - ALB: $0.0225/hour + $0.008/GB processed + per-rule charges
+ - Lower cost at high volume
+
+#### TLS Termination at NLB
+
+**Common Misconception:**
+
+> "NLBs don't terminate TLS - they're Layer 4 pass-through only"
+
+**Reality:**
+NLBs **DO support TLS termination** when configured with ACM certificates via the AWS Load Balancer Controller.
+
+**Configuration:**
+
+```hcl
+service_annotations = {
+ "service.beta.kubernetes.io/aws-load-balancer-ssl-cert" = data.aws_acm_certificate.coder.arn
+ "service.beta.kubernetes.io/aws-load-balancer-ssl-ports" = "443"
+}
+```
+
+**Traffic Flow:**
+
+```
+User (HTTPS:443) β NLB (terminates TLS) β Coder Backend (HTTP:8080)
+```
+
+**Coder Configuration:**
+
+```hcl
+env_vars = {
+ CODER_REDIRECT_TO_ACCESS_URL = "false" # Prevent redirect loops
+ CODER_TLS_ENABLE = "false" # NLB handles TLS
+ CODER_SECURE_AUTH_COOKIE = "true" # Users connect via HTTPS
+}
+```
+
+**Official Documentation:**
+
+- [AWS: Create TLS Listener for NLB](https://docs.aws.amazon.com/elasticloadbalancing/latest/network/create-tls-listener.html)
+- [AWS: NLB TLS Termination Announcement](https://aws.amazon.com/blogs/aws/new-tls-termination-for-network-load-balancers/)
+- [AWS Load Balancer Controller: NLB TLS Termination](https://kubernetes-sigs.github.io/aws-load-balancer-controller/latest/guide/use_cases/nlb_tls_termination/)
+
+#### When to Use ALB Instead
+
+Consider ALB only if you need:
+
+- Path-based routing (`/api` β service A, `/web` β service B)
+- Host-based routing (multiple domains to different backends)
+- HTTP-level features (redirects, header manipulation, authentication)
+- WAF (Web Application Firewall) integration
+- More detailed HTTP metrics
+
+**For Coder:** These features are not needed - it's a single application without complex routing requirements.
+
+---
+
+## DNS and Multi-Region Setup
+
+### Architecture Overview
+
+**Root Domain:** `coderdemo.io` (Route53 hosted zone)
+
+**DNS Records:**
+
+#### 1. Latency-Based Routing (Automatic)
+
+```
+coderdemo.io β Routes to nearest region (us-east-2 or us-west-2)
+*.coderdemo.io β Wildcard for workspace apps (latency-routed)
+```
+
+**Configuration:**
+
+```hcl
+resource "aws_route53_record" "coder_latency" {
+ zone_id = var.hosted_zone_id
+ name = var.domain_name
+ type = "A"
+ set_identifier = var.set_identifier # e.g., "us-east-2"
+
+ alias {
+ name = local.nlb_hostname
+ zone_id = data.aws_lb.coder_nlb.zone_id
+ evaluate_target_health = true
+ }
+
+ latency_routing_policy {
+ region = var.cluster_region
+ }
+
+ health_check_id = aws_route53_health_check.coder[0].id
+}
+```
+
+#### 2. Region-Specific Subdomains (Manual Selection)
+
+```
+us-east-2.coderdemo.io β Force Ohio region
+us-west-2.coderdemo.io β Force Oregon region
+*.us-east-2.coderdemo.io β Ohio workspace apps
+*.us-west-2.coderdemo.io β Oregon workspace apps
+```
+
+**Use Case:**
+Instructor in East Coast can join West Coast customer demo by using `us-west-2.coderdemo.io` instead of relying on latency-based routing.
+
+### Benefits
+
+1. **Automatic Failover**
+ - Route53 health checks monitor each region
+ - Unhealthy regions automatically removed from rotation
+ - Users transparently routed to healthy region
+
+2. **Performance Optimization**
+ - Users connect to geographically nearest region
+ - Lower latency for all interactions
+ - Better experience for global teams
+
+3. **Manual Override**
+ - Region-specific URLs allow explicit region selection
+ - Useful for demos, testing, or specific customer requirements
+ - No code changes needed - just use different URL
+
+### Multi-Region Coder Visibility
+
+**Current State:**
+
+- Only `us-east-2` appears in Coder's region dropdown
+- `us-west-2` infrastructure code exists but not deployed
+
+**For us-west-2 to Appear:**
+
+1. Deploy ACM certificates (`infra/aws/us-west-2/acm/`)
+2. Deploy Coder server (`infra/aws/us-west-2/k8s/coder-server/`)
+3. Deploy Route53 records (`infra/aws/us-west-2/route53/`)
+4. Ensure shared RDS database or database replication
+
+**Important:** Both regions must use the same database for unified user accounts and workspace state.
+
+---
+
+## LiteLLM Integration Architecture
+
+### Decision: Separate Service with Subdomain
+
+**Architecture:**
+
+```
+coderdemo.io β Coder (latency-routed)
+llm.coderdemo.io β LiteLLM (separate NLB)
+```
+
+**Deployment:**
+
+- LiteLLM: Separate Kubernetes deployment with own NLB
+- Each Coder workspace namespace gets LiteLLM API keys via secret rotation
+- Keys automatically rotated from AWS Secrets Manager
+
+**Why This Approach:**
+
+#### Option 1: Separate Subdomain β
(Implemented)
+
+**Advantages:**
+
+- Keep NLB for both services (no ALB needed)
+- Clean separation of concerns
+- Independent scaling and monitoring
+- No path rewriting complexity
+
+#### Option 2: Path-Based Routing (Not Recommended)
+
+```
+coderdemo.io/ β Coder
+coderdemo.io/v1/* β LiteLLM
+```
+
+**Disadvantages:**
+
+- Requires switching to ALB
+- More complex configuration
+- Potential URL rewriting issues
+- No clear benefit for this use case
+
+#### Option 3: Internal Only (Alternative)
+
+**For Maximum Security:**
+
+- Don't expose LiteLLM externally at all
+- Coder communicates via internal Kubernetes service DNS
+- Only Coder β LiteLLM traffic allowed
+- No additional load balancer needed
+
+### Current Implementation
+
+**LiteLLM Service:** `infra/aws/us-east-2/k8s/litellm/main.tf`
+
+- 4 replicas with 2 CPU / 4Gi memory each
+- Own ACM certificate for TLS termination
+- Connected to PostgreSQL (RDS) and Redis
+- Automatic key generation and rotation
+
+**Workspace Integration:** `infra/aws/us-east-2/k8s/coder-ws/main.tf`
+
+```hcl
+module "default-ws-litellm-rotate-key" {
+ source = "../../../../../modules/k8s/bootstrap/litellm-rotate-key"
+ namespace = "coder-ws"
+ secret_id = var.aws_secret_id
+ secret_region = var.aws_secret_region
+}
+```
+
+**Key Rotation:**
+
+- Keys fetched from AWS Secrets Manager
+- Injected as Kubernetes secrets into workspace namespaces
+- Workspaces use keys to make LLM API calls through LiteLLM
+- Rotation happens automatically without workspace downtime
+
+---
+
+## Helm Chart Management
+
+### Decision: Enable `upgrade_install` on All Helm Releases
+
+**What We Did:**
+Added `upgrade_install = true` to all `helm_release` resources across the codebase.
+
+**Files Updated:**
+
+- `modules/k8s/bootstrap/karpenter/main.tf`
+- `modules/k8s/bootstrap/ebs-controller/main.tf`
+- `modules/k8s/bootstrap/lb-controller/main.tf`
+- `modules/k8s/bootstrap/cert-manager/main.tf`
+- `modules/k8s/bootstrap/coder-server/main.tf`
+- `modules/k8s/bootstrap/coder-proxy/main.tf`
+- `modules/k8s/bootstrap/metrics-server/main.tf`
+
+**Configuration:**
+
+```hcl
+resource "helm_release" "example" {
+ name = "example"
+ namespace = var.namespace
+ chart = "example"
+ repository = "https://charts.example.com"
+ create_namespace = true
+ upgrade_install = true # β Critical for idempotent deployments
+ skip_crds = false
+ wait = true
+ wait_for_jobs = true
+ version = var.chart_version
+}
+```
+
+**Why This Matters:**
+
+1. **Idempotent Terraform Applies**
+ - Without `upgrade_install`: Terraform fails if release already exists
+ - With `upgrade_install`: Terraform upgrades existing release or installs new one
+ - Essential for repeatable deployments
+
+2. **Version Management**
+ - Allows Terraform to manage chart version upgrades
+ - No manual `helm upgrade` commands needed
+ - Declarative infrastructure-as-code
+
+3. **CI/CD Integration**
+ - Pipelines can safely re-run Terraform apply
+ - No "already exists" errors in automation
+ - Cleaner error handling
+
+**Helm Provider Version:**
+
+```hcl
+helm = {
+ source = "hashicorp/helm"
+ version = "3.1.1" # upgrade_install re-added in this version
+}
+```
+
+**Historical Context:**
+The `upgrade_install` parameter was temporarily removed from the Helm provider in earlier versions, leading to comments in code saying it was "invalid". It was re-added in version 3.1.1 and should now be used as a best practice.
+
+---
+
+## Security Considerations
+
+### TLS/SSL Certificate Management
+
+**ACM Certificates:**
+
+```hcl
+data "aws_acm_certificate" "coder" {
+ domain = trimsuffix(trimprefix(var.coder_access_url, "https://"), "/")
+ statuses = ["ISSUED"]
+ most_recent = true
+}
+```
+
+**Best Practices:**
+
+1. Use ACM for automatic certificate renewal
+2. Fetch certificates dynamically (don't hardcode ARNs)
+3. Filter by `ISSUED` status to avoid revoked certs
+4. Use `most_recent` for automatic updates
+
+### Service Account Permissions
+
+**Principle of Least Privilege:**
+
+```hcl
+oidc_principals = {
+ "${var.cluster_oidc_provider_arn}" = [
+ "system:serviceaccount:${var.namespace}:coder"
+ ]
+}
+```
+
+**Why:**
+
+- Restrict IAM role assumption to specific service accounts
+- Prevents any pod from assuming sensitive roles
+- Scoped to specific namespace and service account name
+
+### Source IP Preservation
+
+**NLB Advantage:**
+
+- Client source IP preserved in connection
+- Available in Coder's audit logs
+- No header parsing needed
+- Better security monitoring and rate limiting
+
+**With ALB:**
+
+- Source IP only available in `X-Forwarded-For` header
+- Application must parse headers
+- Less reliable (headers can be spoofed)
+
+---
+
+## Key Takeaways for Sales Engineers
+
+### When Discussing Load Balancers
+
+1. **NLB is the right choice for Coder**
+ - Optimized for long-lived WebSocket connections
+ - Lower latency than ALB
+ - Source IP preservation for audit logs
+ - Static IPs for enterprise firewalls
+
+2. **NLB DOES support TLS termination**
+ - Common misconception that it doesn't
+ - Fully supported via ACM certificates
+ - Show AWS documentation if questioned
+
+3. **ALB only needed if:**
+ - Path-based routing required
+ - WAF integration needed
+ - HTTP-specific features required
+ - None of these apply to standard Coder deployments
+
+### When Discussing Multi-Region
+
+1. **Latency-based routing provides:**
+ - Automatic performance optimization
+ - Built-in failover
+ - No user action required
+
+2. **Region-specific URLs allow:**
+ - Manual region override
+ - Demo flexibility
+ - Testing and troubleshooting
+
+3. **Shared database is critical:**
+ - Users need unified accounts across regions
+ - Workspace state must be accessible everywhere
+ - Consider RDS read replicas for performance
+
+### When Discussing LiteLLM
+
+1. **Separate subdomain approach:**
+ - Keeps architecture simple
+ - No ALB needed
+ - Independent scaling
+ - Clear separation of concerns
+
+2. **Automatic key rotation:**
+ - Security best practice
+ - No manual key management
+ - Zero downtime rotation
+ - AWS Secrets Manager integration
+
+3. **Internal-only option available:**
+ - Maximum security
+ - No external exposure
+ - Simpler architecture
+ - Recommended if no external access needed
+
+### When Discussing Infrastructure as Code
+
+1. **`upgrade_install = true` is critical:**
+ - Enables idempotent Terraform applies
+ - Required for CI/CD pipelines
+ - Prevents deployment failures
+ - Standard best practice
+
+2. **Terraform module structure:**
+ - Reusable across regions
+ - Consistent configuration
+ - Easy to add new regions
+ - Clear separation of concerns

+# Multi-Region Deployment Progress
+
+**Date:** 2025-12-02
+**Status:** Pending Enterprise License
+
+## Overview
+
+This document tracks the progress of deploying multi-region Coder infrastructure to enable:
+
+- **A) Automatic routing** to the nearest region based on user latency
+- **B) Manual region selection** in the Coder UI for users to choose their preferred region
+
+## Current Status
+
+### β
Completed Today
+
+#### 1. Cost Optimization - Aurora Serverless v2
+
+- **Problem:** RDS Aurora Serverless v2 costing $130/month for both writer and reader instances
+- **Solution:** Removed reader instance from `infra/aws/us-east-2/rds/main.tf`
+- **Result:** Reduced cost by ~$44/month to ~$86/month (1.0 ACU total)
+- **File:** `infra/aws/us-east-2/rds/main.tf`
+
+#### 2. Cross-Region Replica Communication
+
+- **Problem:** Coder replicas in us-east-2 and us-west-2 could detect each other but couldn't communicate (timeout errors)
+- **Root Cause:** Security groups blocking port 8080 traffic between VPCs
+- **Solution:**
+ - Added security group rules to allow TCP port 8080 between VPC CIDRs
+ - Codified rules in Terraform for reproducibility
+- **Files:**
+ - `infra/aws/us-east-2/vpc-peering/main.tf`
+ - `infra/aws/us-east-2/vpc-peering/terraform.tfvars`
+
+```terraform
+# Security group rule to allow Coder replica communication from us-west-2 to us-east-2
+resource "aws_security_group_rule" "use2_allow_coder_from_usw2" {
+ provider = aws.use2
+ type = "ingress"
+ from_port = 8080
+ to_port = 8080
+ protocol = "tcp"
+ cidr_blocks = [var.accepter_vpc_cidr]
+ security_group_id = var.requester_node_security_group_id
+ description = "Allow Coder replica communication from us-west-2"
+}
+```
+
+#### 3. DERP Server Configuration
+
+- **Problem:** `/derp/latency-check` endpoint timing out, replicas couldn't sync properly
+- **Root Cause:** `CODER_DERP_SERVER_ENABLE` environment variable not set
+- **Solution:** Added `CODER_DERP_SERVER_ENABLE = "true"` to both regions' Coder deployments
+- **Result:** Replicas now communicate successfully, no more timeout errors
+- **Files:**
+ - `infra/aws/us-east-2/k8s/coder-server/main.tf`
+ - `infra/aws/us-west-2/k8s/coder-server/main.tf`
+
+```terraform
+env_vars = {
+ CODER_REDIRECT_TO_ACCESS_URL = "false"
+ CODER_TLS_ENABLE = "false"
+ CODER_SECURE_AUTH_COOKIE = "true"
+ # Enable DERP server for multi-region replica communication
+ CODER_DERP_SERVER_ENABLE = "true"
+}
+```
+
+#### 4. Latency Improvement
+
+- **Before:** 111ms
+- **After:** 34ms
+- Achieved through proper VPC peering, security group rules, and DERP server configuration
+
+#### 5. Workspace Proxy Configuration (Ready for Deployment)
+
+- Created complete Terraform configuration for us-west-2 workspace proxy
+- **Files:**
+ - `infra/aws/us-west-2/k8s/coder-proxy/main.tf`
+ - `infra/aws/us-west-2/k8s/coder-proxy/terraform.tfvars`
+ - `infra/aws/us-west-2/k8s/coder-proxy/backend.hcl`
+
+### βΈοΈ Blocked - Awaiting Enterprise License
+
+#### Workspace Proxy Deployment
+
+- **Problem:** "Your license is not entitled to create workspace proxies."
+- **Requirement:** Coder Enterprise license required for Workspace Proxy feature
+- **Impact:** Manual region selection (requirement B) cannot be completed without Enterprise license
+
+**Error from Terraform:**
+
+```
+Error: Feature not enabled
+
+ with module.coder-proxy.coderd_workspace_proxy.this,
+ on ../../../../../modules/k8s/bootstrap/coder-proxy/main.tf line 259, in resource "coderd_workspace_proxy" "this":
+ 259: resource "coderd_workspace_proxy" "this" {
+
+Your license is not entitled to create workspace proxies.
+```
+
+**Error from API:**
+
+```json
+{
+ "message": "Workspace Proxy is a Premium feature. Contact sales!"
+}
+```
+
+## Key Technical Concepts
+
+### Coder Replicas vs Workspace Proxies
+
+#### Replicas (Currently Deployed)
+
+- **Purpose:** High availability and automatic failover
+- **Behavior:** Multiple Coder instances share same database, automatic failover if one fails
+- **User Experience:** Users see single "default" region, automatic routing based on DNS
+- **License:** Available in all Coder editions
+- **Status:** β
Deployed and working in us-east-2 and us-west-2
+
+#### Workspace Proxies (Blocked by License)
+
+- **Purpose:** User-selectable regions for manual region switching
+- **Behavior:** Users can see and manually switch between regions in Coder UI
+- **User Experience:** "Region" tab in UI with latency display and manual selection
+- **License:** β οΈ Requires Coder Enterprise license
+- **Status:** β Configuration ready but deployment blocked
+

+
+## Next Steps - Once Enterprise License is Obtained
+
+### 1. Apply Enterprise License to Coder Deployment
+
+The license needs to be applied to the primary Coder deployment at https://coderdemo.io. This is typically done through the Coder admin UI or by setting the `CODER_LICENSE` environment variable.
+
+### 2. Deploy Workspace Proxy to us-west-2
+
+Run from `infra/aws/us-west-2/k8s/coder-proxy`:
+
+```bash
+terraform apply -var-file=terraform.tfvars -auto-approve
+```
+
+This will:
+
+1. Create the workspace proxy "Oregon" in Coder API
+2. Deploy proxy pods to us-west-2 EKS cluster
+3. Create namespace and secrets
+4. Configure NLB with ACM certificate
+5. Enable manual region selection in Coder UI
+
+### 3. Verify Workspace Proxy Registration
+
+Check that the proxy appears in Coder:
+
+```bash
+curl -H "Coder-Session-Token: " https://coderdemo.io/api/v2/workspaceproxies
+```
+
+Expected response:
+
+```json
+{
+ "proxies": [
+ {
+ "id": "...",
+ "name": "us-west-2",
+ "display_name": "Oregon",
+ "icon": "/emojis/1f1fa-1f1f8.png",
+ "url": "https://us-west-2.coderdemo.io",
+ "healthy": true
+ }
+ ]
+}
+```
+
+### 4. Configure Route53 (If Not Already Done)
+
+Ensure latency-based routing is configured for automatic region selection:
+
+- A record for `coderdemo.io` β us-east-2 NLB (latency-based)
+- A record for `coderdemo.io` β us-west-2 NLB (latency-based)
+- CNAME for `*.coderdemo.io` β coderdemo.io
+- A record for `us-west-2.coderdemo.io` β us-west-2 NLB (simple routing)
+
+### 5. Test User Experience
+
+1. Navigate to https://coderdemo.io
+2. Verify latency-based routing connects to nearest region
+3. Look for "Region" selector in Coder UI
+4. Click "Refresh latency" to see both regions
+5. Manually select "Oregon" region
+6. Verify connection switches to us-west-2
+

+
+## Important Notes
+
+1. **Token Security:** The Coder API token is stored in terraform.tfvars. Consider using AWS Secrets Manager for production.
+
+2. **S3 Backend:** All Terraform state is stored in S3 bucket in us-east-2. See backend.hcl files for configuration.
+
+3. **Replica Communication:** Replicas use DERP protocol on port 8080 for coordination. Ensure security groups allow this traffic.
+
+4. **DNS Propagation:** After deploying workspace proxy, DNS changes may take 5-60 minutes to propagate globally.
+
+5. **Certificate Management:** ACM certificates are managed separately. Ensure `*.us-west-2.coderdemo.io` certificate is issued in us-west-2.
+
+## Troubleshooting
+
+### If Workspace Proxy Deployment Fails
+
+1. Verify Enterprise license is applied: Check Coder admin UI β Deployment β License
+2. Check Coder API token has admin permissions
+3. Verify network connectivity from us-west-2 to primary deployment
+4. Check pod logs: `kubectl logs -n coder-proxy -l app.kubernetes.io/name=coder`
+
+### If Users Don't See Region Selector
+
+1. Ensure workspace proxy status is "healthy" in API
+2. Hard refresh browser (Cmd+Shift+R / Ctrl+Shift+F5)
+3. Verify user has permission to see workspace proxies
+4. Check Coder version supports workspace proxies (v2.0+)
+
+## Summary
+
+**What Works Now:**
+
+- β
Multi-region Coder replicas (us-east-2, us-west-2)
+- β
Automatic failover between replicas
+- β
Cross-region communication via DERP
+- β
34ms inter-region latency
+- β
Cost-optimized Aurora database
+
+**What's Pending:**
+
+- βΈοΈ Manual region selection in UI (blocked by Enterprise license)
+- βΈοΈ Workspace proxy deployment (configuration ready)
+
+**Action Required:**
+
+1. Obtain Coder Enterprise license
+2. Apply license to deployment
+3. Run `terraform apply` for workspace proxy
+4. Verify region selector appears in UI

+# Cost Optimization Strategy for Coder Demo
+
+## Mixed Capacity Approach
+
+### Node Group Strategy
+
+**System Nodes (ON_DEMAND)**
+
+- **Purpose**: Run critical Kubernetes infrastructure
+- **Workloads**: CoreDNS, kube-proxy, metrics-server, cert-manager, AWS LB Controller
+- **Size**: t4g.medium (ARM Graviton)
+- **Count**: 1-2 nodes minimum
+- **Cost**: ~$24/month (1 node) to $48/month (2 nodes)
+
+**Application Nodes (MIXED: 20% On-Demand, 80% Spot via Karpenter)**
+
+- **Purpose**: Run Coder server and workspaces
+- **Spot Savings**: 70-90% cost reduction
+- **Interruption Risk**: Mitigated by:
+ - Multiple instance types (diversified Spot pools)
+ - Karpenter auto-rebalancing
+ - Pod Disruption Budgets
+
+### Karpenter NodePool Configuration
+
+#### 1. Coder Server NodePool (ON_DEMAND Priority)
+
+```yaml
+capacity_type: ["on-demand", "spot"] # Prefer On-Demand, fallback to Spot
+weight:
+ on-demand: 100 # Higher priority
+ spot: 10
+```
+
+#### 2. Coder Workspace NodePool (SPOT Priority)
+
+```yaml
+capacity_type: ["spot", "on-demand"] # Prefer Spot, fallback to On-Demand
+weight:
+ spot: 100 # Higher priority
+ on-demand: 10
+```
+
+### Risk Mitigation
+
+**Spot Interruption Handling:**
+
+1. **2-minute warning** β Karpenter automatically provisions replacement
+2. **Multiple instance types** β 15+ types reduces interruption rate to <1%
+3. **Pod Disruption Budgets** β Ensures minimum replicas always running
+4. **Karpenter Consolidation** β Automatically moves pods before termination
+
+**Example Instance Type Diversity:**
+
+```
+Spot Pool: t4g.medium, t4g.large, t3a.medium, t3a.large,
+ m6g.medium, m6g.large, m6a.medium, m6a.large
+```
+
+### Cost Breakdown
+
+| Component | Instance Type | Capacity | Monthly Cost |
+| ------------------ | ------------- | --------- | ------------- |
+| System Nodes (2) | t4g.medium | ON_DEMAND | $48 |
+| Coder Server (2) | t4g.large | 80% SPOT | $28 (vs $140) |
+| Workspaces (avg 5) | t4g.xlarge | 90% SPOT | $75 (vs $750) |
+| **Total** | | **Mixed** | **$151/mo** |
+
+**vs All On-Demand:** $938/month β **84% savings**
+
+### Dynamic Scaling
+
+**Low Usage (nights/weekends):**
+
+- Scale to zero workspaces
+- Keep 1 system node + 1 Coder server node
+- Cost: ~$48/month during idle
+
+**High Usage (business hours):**
+
+- Auto-scale workspaces on Spot
+- Karpenter provisions nodes in <60 seconds
+- Cost: ~$150-200/month during peak
+
+### Monitoring & Alerts
+
+**CloudWatch Alarms:**
+
+- Spot interruption rate > 5%
+- Available On-Demand capacity < 20%
+- Karpenter provisioning failures
+
+**Response:**
+
+- Automatic fallback to On-Demand
+- Email alerts to ops team
+- Karpenter adjusts instance type mix
+
+## Implementation Timeline
+
+1. β
Deploy EKS with ON_DEMAND system nodes
+2. β³ Deploy Karpenter
+3. β³ Configure mixed-capacity NodePools
+4. β³ Deploy Coder with node affinity rules
+5. β³ Test Spot interruption handling
+6. β³ Enable auto-scaling policies
+
+## Fallback Plan
+
+If Spot becomes unreliable (rare):
+
+1. Update Karpenter NodePool to 100% On-Demand
+2. `kubectl apply -f nodepool-ondemand.yaml`
+3. Karpenter gracefully migrates pods
+4. Takes ~5 minutes, zero downtime
+
+## Best Practices
+
+β
**DO:**
+
+- Use multiple Spot instance types (10+)
+- Set Pod Disruption Budgets
+- Monitor Spot interruption rates
+- Test failover regularly
+
+β **DON'T:**
+
+- Run databases on Spot (use RDS)
+- Use Spot for single-replica critical services
+- Rely on single instance type for Spot

+# Terraform Backend Configuration
+
+## Security Notice
+
+This directory uses remote S3 backend for state management, but **backend configuration files are gitignored** to prevent leaking AWS account IDs and other sensitive information.
+
+## Local Setup
+
+1. **Get backend configuration from teammate** or **retrieve from AWS**:
+
+ ```bash
+ # Get S3 bucket name (it contains the account ID)
+ aws s3 ls | grep terraform-state
+
+ # Get DynamoDB table name
+ aws dynamodb list-tables --query 'TableNames[?contains(@, `terraform-lock`)]'
+ ```
+
+2. **Create backend configuration** for each module:
+
+ Each Terraform module needs a `backend.tf` file (this file is gitignored). Create it manually:
+
+ ```bash
+ cd infra/aws/us-east-2/vpc # or any other module
+ ```
+
+ Create `backend.tf`:
+
+ ```hcl
+ terraform {
+ backend "s3" {
+ bucket = "YOUR-BUCKET-NAME-HERE"
+ key = "us-east-2/vpc/terraform.tfstate" # Update path per module
+ region = "us-east-2"
+ dynamodb_table = "YOUR-TABLE-NAME-HERE"
+ encrypt = true
+ }
+ }
+ ```
+
+ **Important**: Update the `key` path for each module:
+ - VPC: `us-east-2/vpc/terraform.tfstate`
+ - EKS: `us-east-2/eks/terraform.tfstate`
+ - ACM: `us-east-2/acm/terraform.tfstate`
+ - etc.
+
+3. **Initialize Terraform**:
+ ```bash
+ terraform init
+ ```
+
+## GitHub Actions Setup
+
+GitHub Actions uses secrets to configure the backend securely. Required secrets:
+
+1. `TF_STATE_BUCKET` - S3 bucket name
+2. `TF_STATE_LOCK_TABLE` - DynamoDB table name
+3. `AWS_ROLE_ARN` - IAM role ARN for OIDC authentication
+
+These are configured in: Repository Settings > Secrets and variables > Actions
+
+## Alternative: Using Backend Config File
+
+Instead of creating backend.tf, you can use a config file:
+
+1. Create `backend.conf` (gitignored):
+
+ ```
+ bucket = "YOUR-BUCKET-NAME"
+ dynamodb_table = "YOUR-TABLE-NAME"
+ region = "us-east-2"
+ encrypt = true
+ ```
+
+2. Initialize with:
+ ```bash
+ terraform init -backend-config=backend.conf -backend-config="key=us-east-2/vpc/terraform.tfstate"
+ ```
+
+## Why This Approach?
+
+- **Security**: Account IDs and resource names aren't committed to Git
+- **Flexibility**: Each developer/environment can use different backends
+- **Compliance**: Prevents accidental exposure of infrastructure details
+- **Best Practice**: Follows AWS security recommendations
+
+## Secret Scanning Protection
+
+This repository has automated secret scanning to prevent accidental exposure of credentials:
+
+### GitHub Actions (Automated)
+
+- **Gitleaks** - Scans every PR and push for secrets
+- **TruffleHog** - Additional verification layer
+- **Custom Pattern Matching** - Catches common secret patterns
+- **Auto-Revert** - Automatically reverts commits to main with secrets
+
+### Pre-commit Hooks (Local)
+
+Catch secrets before they reach GitHub:
+
+```bash
+# Install pre-commit
+pip install pre-commit
+
+# Install git hooks
+pre-commit install
+
+# Test on all files
+pre-commit run --all-files
+```
+
+### What Gets Detected
+
+- AWS Access Keys (AKIA...)
+- API Keys and Tokens
+- Private Keys (RSA, SSH, etc.)
+- Database connection strings with passwords
+- GitHub Personal Access Tokens
+- Stripe API keys
+- High-entropy strings (likely secrets)
+
+### If Secrets Are Detected
+
+1. **PR is blocked** - Cannot merge until secrets are removed
+2. **Automatic notification** - PR comment explains the issue
+3. **Required actions**:
+ - Remove the secret from code
+ - Use GitHub Secrets or environment variables
+ - Rotate/invalidate the exposed credential
+
+## Migrating Existing State
+
+If you have local state to migrate:
+
+```bash
+terraform init -migrate-state
+```
+
+Terraform will prompt to copy existing state to the remote backend.

+# Route 53 Latency-Based Routing for Coder
+
+This Terraform configuration sets up Route 53 latency-based routing for the Coder deployment in us-east-2.
+
+## Overview
+
+Latency-based routing automatically directs users to the AWS region that provides the lowest latency, improving the user experience by connecting them to the nearest deployment.
+
+## Features
+
+- **Latency-based routing**: Routes users to the closest region automatically
+- **Health checks**: Monitors endpoint health and routes around failures
+- **Wildcard DNS**: Supports workspace application subdomains
+- **Automatic NLB discovery**: Retrieves NLB hostname from Kubernetes service
+
+## Prerequisites
+
+1. Hosted Zone ID for coderdemo.io (already configured: Z080884039133KJPAGA3S)
+2. Running EKS cluster with Coder deployed
+3. Network Load Balancer created via Kubernetes service
+
+## Deployment
+
+1. Create terraform.tfvars from the example:
+
+```bash
+cp terraform.tfvars.example terraform.tfvars
+```
+
+2. Update terraform.tfvars with your cluster name:
+
+```hcl
+cluster_name = "your-cluster-name"
+```
+
+3. Initialize and apply:
+
+```bash
+terraform init
+terraform plan
+terraform apply
+```
+
+## How It Works
+
+1. The configuration queries the Kubernetes service to get the NLB hostname
+2. Creates Route 53 A records with latency-based routing policy
+3. Sets up health checks to monitor endpoint availability
+4. Configures both main domain and wildcard records
+
+## Health Checks
+
+Health checks monitor the `/api/v2/buildinfo` endpoint on port 443 (HTTPS):
+
+- **Interval**: 30 seconds
+- **Failure threshold**: 3 consecutive failures
+- **Latency measurement**: Enabled for monitoring
+
+## Records Created
+
+- `coderdemo.io` - Main domain with latency routing
+- `*.coderdemo.io` - Wildcard for workspace applications
+
+## Important Notes
+
+- Deploy this configuration in **both** us-east-2 and us-west-2 with different set_identifiers
+- Each region's configuration points to its local NLB
+- Route 53 automatically routes based on measured latency
+- Health checks ensure failover if one region becomes unhealthy
