feat(plane-enterprise): make silo init container image configurable#305KajdeMunter wants to merge 2 commits into
Conversation
The silo deployment's two init containers (`wait-for-rabbitmq` and the S3-CA-gated `prepare-ca-bundle`) hardcoded `busybox`, forcing an unauthenticated Docker Hub pull. That blocks air-gapped installs and private-registry mirroring, and is exposed to Docker Hub rate limits. Add `services.silo.init_image`, following the `services.minio.init_image` convention from makeplane#298, and document it in the README table and questions.yml. Defaults to `busybox`, so rendered output is unchanged unless overridden. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

In `@charts/plane-enterprise/README.md`:
- Line 833: Update the services.silo.init_image documentation to state that
custom init images must be BusyBox-compatible or provide /bin/sh, grep,
nslookup, sleep, ls, cat, and touch, since missing utilities prevent Silo
initialization.

Address CodeRabbit review on makeplane#305: a custom init image must provide the utilities the init scripts invoke (/bin/sh, grep, nslookup, sleep for wait-for-rabbitmq; /bin/sh, ls, cat, touch for prepare-ca-bundle), otherwise the affected init container fails and silo never starts.

What
Makes the
busyboximage used by the silo deployment's init containers configurable inplane-enterprise, via a newservices.silo.init_imagevalue.Both of silo's init containers are covered:
wait-for-rabbitmqprepare-ca-bundleplane.s3CAEnabled— i.e.airgapped.enabled=trueand an S3 CA secret is configuredAlso adds the key to
values.yaml(defaulting tobusybox), the README settings table, andquestions.ymlfor the Rancher UI.Follows the
services.minio.init_imageconvention established in #298 — same key name, same| default "busybox"fallback, same docs surfaces.Why
busyboxwas hardcoded, forcing an unauthenticated pull from Docker Hub. That breaks:prepare-ca-bundlecontainer, which only renders whenairgapped.enabled=true— so the one init container specific to air-gapped deployments was itself unmirrorable.ImagePullBackOffon the init container, leaving silo stuck inInit:and never starting.#298 fixed this for
services.minioin both charts. Silo was the remaining gap inplane-enterprise.Scope / behavior
No default behavior change.
