The live deployment's `prepare-ca-bundle` init container hardcoded `busybox`, forcing an unauthenticated Docker Hub pull. This container only renders when a custom S3 CA is configured (`airgapped.enabled` with an S3 CA secret) -- so the one init container specific to air-gapped installs was itself unmirrorable. Add `services.live.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. `services.live_exporter` needs no equivalent -- it has no init containers.

- Line 730: The services.live.init_image documentation must state that custom
init images need /bin/sh, ls, cat, and touch available, since prepare-ca-bundle
invokes them. Update that key’s description while preserving its existing
purpose and configuration conditions.

What
Makes the
busyboximage used by the live deployment'sprepare-ca-bundleinit container configurable inplane-enterprise, via a newservices.live.init_imagevalue.Also adds the key to
values.yaml(defaulting tobusybox), the README settings table, andquestions.ymlfor the Rancher UI.Follows the
services.minio.init_imageconvention from #298 — same key name, same| default "busybox"fallback, same docs surfaces.Why
busyboxwas hardcoded, forcing an unauthenticated pull from Docker Hub — which breaks private-registry mirroring and is exposed to Docker Hub rate limits, surfacing asImagePullBackOffwith live stuck inInit:.The sharp edge here:
prepare-ca-bundlerenders only whenplane.s3CAEnabledis true — that is,airgapped.enabled=truewith an S3 CA secret configured. So the one init container that exists exclusively for air-gapped installs was itself the one image an air-gapped install couldn't mirror.Scope / behavior
No default behavior change.
values.yamlshipsinit_image: busybox, so rendered output is byte-identical unless overridden.| default "busybox"so an existing values file predating this key — or setting it empty — still rendersbusyboxrather than an emptyimage:field. Upgrades need no values-file change.services.live_exporterdeliberately gets no equivalent key. It shares themakeplane/live-commercialimage but has no init containers at all (verified: 0initContainersblocks), so aninit_imagethere would be dead config.Chart.yamlbumped3.5.2→3.5.3, matching the version-bump convention fix(plane-ce): configurable busybox image + mc alias set for MinIO #298 used.Testing

services.silo.init_image. Independent: different file, different values key. Both bumpChart.yamlto3.5.3, so whichever merges second needs a one-line version rebase.services.minio.init_image+mc alias set; this PR follows its naming and structure.With this and #305 merged, no hardcoded
busyboxremains in either chart.🤖 Generated with Claude Code
