feat(plane-ce): make busybox image configurable for plane-ce

[KajdeMunter]

What

Makes the busybox image used by the MinIO bucket job's init container configurable in plane-ce, via a new minio.image_busybox value.

# charts/plane-ce/templates/workloads/minio.stateful.yaml
       initContainers:
         - name: init
-          image: busybox
+          image: {{ .Values.minio.image_busybox | default "busybox" }}

Also adds the key to values.yaml (defaulting to busybox), the README settings table, and questions.yml for the Rancher UI.

Why

busybox was the only hardcoded image left in the plane-ce chart — every other image (minio.image, minio.image_mc, and the app images) is already overridable. That hardcoded reference forces an unauthenticated pull from Docker Hub, which breaks:

• Air-gapped / private-registry installs, where all images must be mirrored to an internal registry.
• Docker Hub rate limits, which surface as ImagePullBackOff on the init container and leave the bucket job stuck before MinIO is ever provisioned.

This applies the same approach as #178 (plane-enterprise) to plane-ce.

Scope / behavior

No default behavior change. values.yaml ships image_busybox: busybox, so the rendered output is byte-identical unless an operator overrides it.

• Only renders when minio.local_setup=true — the whole template is wrapped in {{- if .Values.minio.local_setup }}. Installs using external S3 are unaffected.
• The template uses | default "busybox" rather than a bare value reference, so an existing values file that predates this key (or sets it empty) still renders busybox instead of an empty image: field. Upgrades need no values-file change.
• Nothing else is touched — no other chart, template, or image reference changes.

Testing

helm lint charts/plane-ce → passes, 0 charts failed.

helm template across the relevant value combinations:

Values	Rendered image:
defaults (local_setup=true)	busybox
image_busybox=my.registry/busybox:1.36	my.registry/busybox:1.36
image_busybox="" (simulates a pre-existing values file)	busybox
local_setup=false	template not rendered

Not deployed to a live cluster — the change is a template-only substitution and the rendered manifests above cover it.

Walkthrough

The chart adds minio.image_busybox, defaults it to busybox, exposes it when local MinIO setup is enabled, uses it for the MinIO client job init container, and documents the setting.

Changes

MinIO BusyBox image configuration

Layer / File(s)	Summary
Configure and wire the MinIO BusyBox image charts/plane-ce/values.yaml, charts/plane-ce/questions.yml, charts/plane-ce/templates/workloads/minio.stateful.yaml, charts/plane-ce/README.md	The chart defines minio.image_busybox with a busybox default, exposes the setting for local MinIO setup, uses it in the init container with a fallback, and documents its purpose.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to ca154

This change makes the MinIO init-container image configurable while preserving the existing default behavior and limiting the effect to local MinIO setup. No actionable merge-blocking risk remains after normal checks and review.

Poem

A rabbit sets the image with care,
BusyBox hops through MinIO air.
A value guides the waiting job,
The chart now greets each DNS hop.
“Configurable!” the bunny sings.
