TL;DR — new GHCR packages are private and cannot be made public from CI. This adds a weekly job that lists the private ones and keeps a single issue up to date, so the manual flip is a known chore instead of invisible drift.

Why there is no automatic fix

I checked before writing this:

  • GitHub publishes every new container package as private. Documented, unavoidable.
  • The org package REST API has nine endpoints — list, get, delete, restore, and the same for versions. There is no PATCH/PUT for visibility. It is a web-UI action only, and it is one-way: public can never be made private again.
  • The org "Package creation" setting controls which visibilities are allowed, not a default.

So no workflow can flip these. This one only surfaces them.

Why it matters

artifact_oci_target_base is ghcr.io/armbian/os/ and the artifact name encodes family and branch (os/kernel-meson-s4t7-current), so every new board family or kernel branch mints a brand-new package — private. And oras pulls anonymously, so a private artifact is a cache miss for anyone building locally without ghcr credentials: they silently fall back to a full rebuild.

What it does

Weekly (and on demand): lists private container packages under WATCH_PREFIXES (os/ by default, so deliberately-internal namespaces like cache-kernel/* stay quiet), then creates / edits / closes one tracking issue. Empty list closes it.

It also shows each package's linked repository. Packages pushed with a PAT are not auto-linked — only GITHUB_TOKEN links them — and an unlinked package inherits no repository access permissions. Worth fixing separately by adding --annotation org.opencontainers.image.source=… to the oras push in the build framework.

Needs secrets.ACCESS_TOKEN (read:packages) to list; issue writes use the builtin GITHUB_TOKEN. Fails loudly if the PAT is missing rather than reporting a false all-clear. Guarded with github.repository_owner == 'armbian' so a fork never opens issues.

Verified

YAML parses; all three embedded scripts pass bash -n; the prefix filter and table rendering were exercised against the real package names (cache-kernel/* correctly excluded, os/* kept), and the empty-list path returns count=0 and takes the close branch.

Worth saying plainly

This manages the symptom. The permanent fix is to stop minting new package names — move family/branch out of the package name and into the tag (os/kernel:meson-s4t7-current-<ver> rather than os/kernel-meson-s4t7-current:<ver>). Armbian would then have ~8 packages total, each made public once, and no new package ever again. When that lands, delete this workflow.

GitHub publishes every new container package as private, and there is no
way to change that from CI -- the org package REST endpoints are
list/get/delete/restore only, so visibility is a web-UI action, and it is
one-way (public can never go back to private).

Armbian's artifact names encode family and branch
(os/kernel-meson-s4t7-current), so every new board family or kernel branch
mints a brand-new package that starts private. That is not cosmetic: oras
pulls anonymously, so a private artifact is a cache MISS for everyone
building locally without ghcr credentials, and they silently fall back to a
full rebuild.

This job cannot fix that. It makes the drift visible: weekly, it lists the
private packages under the watched prefixes (os/ by default, so internal
namespaces like cache-kernel/* stay quiet) and keeps ONE issue up to date,
closing it when the list empties.

It also reports each package's linked repository. Packages pushed with a
PAT are not auto-linked -- only GITHUB_TOKEN links them -- and an unlinked
package inherits no repository access permissions. Adding
org.opencontainers.image.source to the oras push in the build framework
fixes that half separately.

The permanent fix is to stop minting new package names by moving
family/branch out of the package name and into the tag, at which point this
workflow can be deleted.

Walkthrough

The new workflow runs weekly or through workflow_dispatch. It checks for ACCESS_TOKEN, lists private GHCR container packages with gh api, and filters packages by the os/ prefix. It uses GITHUB_TOKEN to open, update, or close a single tracking issue based on the number of matching packages.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to f4694

Overlapping scheduled or manually triggered runs could create duplicate tracking issues when both update the package report at the same time. The workflow remains mergeable, but adding concurrency protection should be followed up to avoid this bounded operational issue.

Comment thread .github/workflows/maintenance-private-packages.yml
The tracking issue is located by title and created when missing, so two
overlapping runs -- a manual dispatch landing on top of the scheduled one --
could both see "no issue" and both create one.

The duplicate would never be cleaned up: the update path picks the first
match and edits only that, so the second issue stays open forever and no
later run touches it.

cancel-in-progress: false rather than true, because killing a run mid-way
could leave an issue created but not filled in.
