| # This workflow builds multiplatform Nosey Parker Docker images for both the Debian and | |
| # Alpine varieties. | |
| # | |
| # For each variety, it uses a native-hardware runner to build the individual | |
| # Docker images, and then merges them into a multiplatform image. | |
| # | |
| # This approach is taken instead of using QEMU, since a QEMU build of Nosey | |
| # Parker takes several hours. Using native runners instead takes a few minutes. | |
| # | |
| # This was adapted from the Docker documentation site: | |
| # https://docs.docker.com/build/ci/github-actions/multi-platform/#distribute-build-across-multiple-runners | |
