Purpose

Allow the Backstage image workflows to publish to OCI registries other than GHCR.

Goals

Keep the current GHCR behavior as the default while allowing repository-level registry configuration.

Approach

Use OCI_REGISTRY_HOST and IMAGE_NAME repository variables. Non-GHCR registries use OCI_REGISTRY_USERNAME and OCI_REGISTRY_PASSWORD secrets; the GitHub actor and token fallback is limited to ghcr.io.

User stories

N/A. CI configuration only.

Release note

Container image publishing can be configured for other OCI registries.

Documentation

N/A. No user-facing behavior changes.

📝 Walkthrough

Walkthrough

The GitHub Actions build and release workflows now support configurable OCI registry hosts, repository prefixes, credentials, image tags, and existence checks. A new empty changeset file was added.

Changes

OCI image publishing

Layer / File(s) Summary
Build workflow publishing
.github/workflows/build-and-test.yml, .changeset/configurable-image-publishing.md
The build workflow uses configurable registry and repository settings, conditional credentials, and the repository prefix for image tags and existence checks.
Release workflow publishing
.github/workflows/release.yml
The release workflow uses configurable registry credentials and repository prefixes for image inspection and retagging.

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

Merge Risk: ⚪ Minimal · up to ae656

Image publishing can now target configurable OCI registries while retaining GHCR defaults and credential fallbacks. No current merge-blocking risk remains.
