| # Builds and pushes the full DocOps Box image matrix to Docker Hub. | |
| # | |
| # The build logic lives in scripts/build-matrix.sh; this workflow is a thin | |
| # harness that sets up the multi-platform build environment and invokes it. | |
| # | |
| # Triggers: | |
| # - Push to `latest` branch (auto-build on merge) | |
| # - Manual dispatch with optional dry-run flag | |
| # | |
| # Required repository secrets: | |
| # DOCKERHUB_USERNAME — Docker Hub username | |
| # DOCKERHUB_PASSWORD — Docker Hub access token (not your password) | |
| # | |
| # To add a new image to the matrix, edit scripts/build-matrix.sh only. | |
