DevOps Bash Toolkit

🚀 A collection of script templates and configurations for DevOps tasks

---

👋 About

Hello! 👋 I'm learning DevOps practices and building this collection of script templates as part of my learning journey. Here you'll find ready-to-use templates for automating various DevOps tasks: monitoring, health checks, backups, deployments, and more.

🔄 Project Status

Project is actively developing and constantly updated with new scripts, configurations and examples as I learn DevOps tools.

• ✨ New templates are regularly added
• 🔧 Existing scripts are improved
• 📚 Documentation is expanded
• 🐛 Found issues are fixed

📚 Sources

Scripts are collected from various sources while learning DevOps:

• 📖 Official documentation - Docker, Kubernetes, Terraform, GitHub Actions, etc.
• ✨ Best Practices - commonly accepted DevOps community practices
• 🎓 Learning materials - courses, tutorials and guides
• 💬 Community - Stack Overflow, GitHub, blogs and forums
• 🔧 Personal experience - adaptation and combination of approaches

🛠️ Technologies

• 🐧 Bash - automation and monitoring scripts
• 🐍 Python - analysis scripts and API work
• 🐳 Docker - containerization and image management
• ☸️ Kubernetes - container orchestration
• 🏗️ Terraform - Infrastructure as Code (IaC)
• 🔄 CI/CD - GitHub Actions, GitLab CI
• 📦 Ansible - configuration automation
• 🌐 Nginx - web server and proxy
• 🔒 SSL/TLS - certificate management

⚠️ Important: All scripts are templates created for educational purposes. They require adaptation to your environment and testing before use in production.
