…rise (1.7.0)
The community chart had five whole-Secret hooks and nothing else, which left four values
with no way out of values.yaml: the registry password, the Postgres DSN, the live server
signing key, and the Cloudflare DNS token. Two of those had no hook at all, and the other
two could only be moved by taking over an entire Secret and owning its config keys too.
This ports the plane-enterprise contract so both charts present one surface to whatever
supplies the Secrets:
- serviceAccount.{create,name,annotations,podLabels,cloudIdentity} across all 12
workloads, so the pods can carry a cloud identity or run as a ServiceAccount managed
outside the chart. The default name is unchanged, so the default render is untouched.
- dockerRegistry.existingSecret, which did not exist — the imagePullSecret name was
hardcoded, so a shared registry token could not be supplied at all.
- external_secrets.ssl_token_existingSecret for the cert-manager DNS-01 token.
- external_secrets.app_keys_existingSecret for SECRET_KEY and LIVE_SERVER_SECRET_KEY.
LIVE_SERVER_SECRET_KEY is rendered into both the app and live Secrets and the two must
agree, so one Secret makes that structural rather than something to remember.
- external_secrets.storage for an S3-compatible backend with no workload identity.
- env.requireExplicitSecrets, to fail the render rather than fall back to this chart's
published example keys.
The AWS keys in the remote-storage branch are now omitted when unset instead of rendered
empty. Both halves of that matter and for different reasons: an empty AWS_ACCESS_KEY_ID
is found first in the SDK credential chain and used, so it beats an attached pod identity
and fails every request; and an empty AWS_REGION is *present*, so a code-side default
never applies and a signed request goes out with no region at all.
The app-keys Secret is mounted only on Plane's own services — api, worker, beat-worker,
live and the migrator. The bundled MinIO, Postgres and RabbitMQ are the datastores
themselves and take only their own credentials; the first pass over-applied it to all
three, and MinIO's bucket-init job additionally uses a different indent depth, which the
render caught.
Rotation caveat, stated plainly rather than implied: the community image configures its
database with a DSN, so there is no discrete-parts path and a managed rotation cannot
reach it. The database/redis/broker credential mirrors are deliberately not added here —
shipping a values surface the image cannot consume would be worse than the gap. That
needs upstream app support first.
Verified with hack/: the resolved environment of every container is byte-identical on the
default render; eight configurations render valid YAML including all hooks at once and
the legacy groups; with app_keys set neither signing key remains in any rendered Secret;
in the keyless case the AWS keys and region are absent rather than empty; and
requireExplicitSecrets catches a blanked key.

🌐 Web query:
Kubernetes Pod API envFrom duplicate environment variable precedence order later source
💡 Result:
In Kubernetes, when environment variables are defined using both env and envFrom, or multiple envFrom sources, the following precedence rules apply: 1. Inline env entries have the highest precedence and will override any values defined via envFrom if the keys are identical [1][2][3]. 2. For multiple envFrom sources, if a key exists in more than one source, the value from the last source defined in the list takes precedence [1][4][3]. In summary, environment variables are processed such that values defined later in the configuration hierarchy override those defined earlier, with explicit env definitions acting as the final override layer [1][3]. Note that while inline env variables can override envFrom values, they cannot use the $(VAR_NAME) syntax to reference variables loaded from envFrom [3].

Move plane.appKeysSecretRef after all other envFrom sources.
The helper is first in all five CE workloads that use it. A later app_env_existingSecret or live_env_existingSecret can override SECRET_KEY or LIVE_SERVER_SECRET_KEY, causing services to use different signing keys. Apply the new order to api.deployment.yaml, beat-worker.deployment.yaml, live.deployment.yaml, migrator.job.yaml, and worker.deployment.yaml.

Use a separate cloud-identity ServiceAccount.
When serviceAccount.annotations binds a cloud role, every workload that uses this shared account receives that role. This includes PostgreSQL, RabbitMQ, MinIO, and frontend pods that do not require object-storage access.
A compromise of any such pod can access resources allowed by the cloud role. Provide a dedicated identity-bearing ServiceAccount for only the workloads that require cloud storage access. Keep infrastructure workloads on a separate least-privilege account.

Same gap as plane-enterprise: the hooks existed only in values.yaml, so the Rancher UI offered no way to reach them. Adds live_env_existingSecret (already in values but never surfaced), the two shared key groups, the storage credential Secret, the registry pull secret, the ServiceAccount block and env.requireExplicitSecrets. The SECRET_KEY description spells out the consequence rather than the mechanism: it derives the key that encrypts the instance-configuration rows, so changing it makes the stored SMTP password and OAuth client secrets undecryptable, and it fails silently.

Description
The community chart had five whole-Secret hooks and nothing else, which left four committed values with no way out of
values.yaml:dockerRegistry.passwordssl.tokenenv.live_server_secret_keyapp_env_existingSecret/live_env_existingSecret, i.e. take over an entire Secret and own its config keys tooenv.pgdb_remote_urlThis ports the plane-enterprise contract so both public charts present one surface to whatever supplies the Secrets.
What's added
serviceAccount.{create,name,annotations,podLabels,cloudIdentity}across all 12 workloads, so pods can carry a cloud identity (IRSA / EKS Pod Identity / GKE / Azure WI) or run as a ServiceAccount managed outside the chart. Default name unchanged.dockerRegistry.existingSecret, and the chart's own registry Secret is skipped when it is set.external_secrets.ssl_token_existingSecretfor the DNS-01 token, with the issuer refs pointed at the supplied name.external_secrets.app_keys_existingSecretforSECRET_KEY+LIVE_SERVER_SECRET_KEY.LIVE_SERVER_SECRET_KEYis rendered into both the app and live Secrets and the two must agree, so one Secret makes that structural instead of something to remember.external_secrets.storage.{secretName,accessKeyIdKey,secretAccessKeyKey}for an S3-compatible backend with no workload identity.env.requireExplicitSecretsto fail the render rather than fall back to this chart's published example keys.The empty-vs-absent fix
The AWS keys in the remote-storage branch are now omitted when unset instead of rendered
"". Both halves matter, for different reasons:AWS_ACCESS_KEY_IDis found first in the SDK credential chain and used, so it beats an attached pod identity and fails every request with a misleadingHeadBucket 400.AWS_REGIONis present, so a code-sideget(..., "us-east-1")default never applies, and a signed request goes out with no region.Rotation caveat, stated rather than implied
The community image configures its database with a DSN, so there is no discrete-parts path and a managed rotation cannot reach it — the password is baked into a string that something outside the app would have to recompose.
The
database/redis/rabbitmqcredential mirrors that plane-enterprise has are therefore deliberately not added here. Shipping a values surface the image cannot consume would be worse than the gap. That needs upstreammakeplane/planesupport first, and is the natural 1.8.0.Type of Change
Test Scenarios
Additive invariant: the resolved environment of every container —
envFromin list order, then explicitenvon top — is byte-identical on the default render.Eight configurations render valid YAML: defaults,
app_keys, registryexistingSecret, external SSL token, storage mirror, ServiceAccount override, the legacy groups, and everything at once.helm lintclean.app_keys_existingSecretset, neither signing key remains in any rendered Secret.AWS_ACCESS_KEY_ID,AWS_SECRET_ACCESS_KEYandAWS_REGIONare absent from every container, not empty.requireExplicitSecrets: truewith a blanked key fails the render with a message naming the value.One thing the render caught: the first pass mounted the app-keys Secret on the bundled MinIO, Postgres and RabbitMQ. Those are the datastores themselves, not Plane services — they take only their own credentials — and MinIO's bucket-init job uses a different indent depth, so it produced invalid YAML. It is now mounted only on api, worker, beat-worker, live and the migrator.
Not covered: no live cluster apply.
