ci: mirror PHP images to ghcr.io alongside Docker Hub#107
Merged
Conversation
Push every built image (base, fpm, unit, unit-dev) to both skilldlabs/php (Docker Hub) and ghcr.io/skilld-labs/php in a single build-push-action step, so both registries get the same multi-arch digest with no rebuild or re-pull. - Add GHCR_REGISTRY env and ghcr.io login (github.actor/GITHUB_TOKEN) to all jobs in the reusable build-php.yml - Append ghcr tags to base/fpm/unit/unit-dev pushes (incl. :version) - Grant packages: write in build-php.yml and in the 8.3/8.4/8.5 callers (caller governs GITHUB_TOKEN scope for workflow_call) - Document the dual registry in CLAUDE.md Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Code Review
This pull request updates the CLAUDE.md documentation to reflect that PHP Docker images are now published to both Docker Hub and GitHub Container Registry (GHCR) from a single build. It adds a new 'Container Registries' section detailing the registry configurations, authentication, permissions, and tagging strategies. There are no review comments, so I have no feedback to provide.
