feat(plane-ce): externalize the credentials that had no way out of values.yaml - #285
Merged

Conversation
…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.

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.

…ions in Rancher Two review findings, both real. plane.appKeysSecretRef was FIRST in envFrom on all five workloads that use it. envFrom is later-source-wins, so an operator setting app_keys_existingSecret alongside app_env_existingSecret or live_env_existingSecret would have the latter override SECRET_KEY and LIVE_SERVER_SECRET_KEY. That defeats the hook's only purpose: those two keys are rendered into both the app and live Secrets and must agree, and an override landing on one workload but not the other breaks live-server auth with no error anywhere. Moved last on api, worker, beat-worker, live and the migrator, with the reason recorded at each call site so it does not drift back. questions.yml declared serviceAccount.annotations as type: string. Rancher sends that as a scalar and the template toYaml's it straight into metadata.annotations, which Kubernetes requires to be a map -- so a non-empty answer produced an invalid ServiceAccount. No Rancher question type yields a map, so the field cannot be offered there safely; the question is removed and values.yaml now says the field is Helm-only. Helm users are unaffected either way, and the "" default meant this only ever broke through the UI. values.yaml also now states what the shared account implies: every workload uses it, datastores included, so an annotation binding a cloud role grants that role to postgres, redis, rabbitmq and minio as well. serviceAccount.name is the way out. Verified: app-keys is last in all five envFrom chains with both hooks set; default render is still 0 lines different from master; a sentinel credential appears 0 times with the hook set; lint clean, 32 documents.

Four credentials in this chart had no way out of
values.yaml. The community chart shipped five whole-Secret hooks and nothing else, so anything not covered by them had to be committed:dockerRegistry.passwordssl.tokenenv.live_server_secret_keyapp_env_existingSecret/live_env_existingSecret, config keys and allenv.pgdb_remote_urlThis ports the plane-enterprise contract so both public charts present one surface to whatever supplies the Secrets — External Secrets Operator, sealed-secrets, or a human.
Decide before merging: the version collides
Master is already at
version: 1.7.0, and this PR does not bump it. Nothing is broken today — published newest is 1.6.3 — but 1.7.0 currently describes two different charts: master's without this contract, and this branch's with it.So either merge this before 1.7.0 is released, or bump it to 1.7.1.
This matters because the failure is silent. A hook set on a chart that does not implement it is simply ignored: the credential renders from
values.yamlexactly as before. An operator would see a green deployment and believe the credential had moved.What this adds
serviceAccount.{create,name,annotations,podLabels,cloudIdentity}across all 12 workloads, so pods can carry a cloud identity (IRSA, EKS Pod Identity, GKE, Azure Workload Identity) or run as a ServiceAccount managed outside the chart. Default name unchanged.dockerRegistry.existingSecret— the chart skips rendering its own registry Secret when set.external_secrets.ssl_token_existingSecretfor the DNS-01 token, with the issuer refs repointed.external_secrets.app_keys_existingSecretforSECRET_KEY+LIVE_SERVER_SECRET_KEY. The latter is rendered into both the app and live Secrets and the two must agree, so one Secret makes that agreement structural rather than 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, not 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.A limit, 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 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.Verification
Additive invariant. The resolved environment of every container —
envFromin list order, then explicitenvon top — is byte-identical on the default render. Re-checked after merging master: 0 differing lines against master's plane-ce.Eight configurations render valid YAML: defaults,
app_keys, registryexistingSecret, external SSL token, storage mirror, ServiceAccount override, the legacy groups, and all of it at once.helm lintclean, 32 documents.app_keys_existingSecretset, neither signing key remains in any rendered Secret, and a sentinel value inenv.secret_keyappears 0 times.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.
Note on the merge
This branch has master merged in to clear conflicts from #300 (Traefik TLS /
WEB_URLscheme) and #298 (configurable busybox +mc alias set). Those two are master's changes, not this PR's — any auto-generated release notes above that credit TLS/Traefik entrypoints or the MinIO init image to this PR are attributing them wrongly.The only real conflict was
_helpers.tpl, where both sides added different helpers at the same point; both are kept and all 16 defines are present. Master's fixes are verified intact after the merge.
