to ghcr.io (github). Images are now first build with '-build'
appended to the tag. E.g. ghcr.io/mailu/admin:master-build.
This is to prevent the image being available before automatic testing has completed.
In the deploy job, the final image is pushed (this still works the same).
Update setup & documentation for switch to ghcr.io
- Build images & build cache are pushed to ghcr.io.
- Tests will make use of the images pushed to ghcr.io.
- Deploy step only copies images from ghcr.io to docker.io.
- Resolves strange build errors tied to buildx+intermediate builds
- Results in quicker build times.
Build base image before the other images.
Change cache key to make it is re-used for all builds. This is not
dangerous. The docker build process can determine itself whether
a cache can be safely re-used or not.
The previous method of using gha cache via buildx proved to be
unreliable. Using local cache via actions/cache@v3 is much more
reliable.
The build job will re-use cache from previous workflow runs.
The total workflow time is still similar ~12 minutes.
- The main workflow file has been optimised and simplified.
- Images are built in parallel when building locally resulting in faster build times.
- The github action workflow is about 50% faster.
- Arm images are built as well. These images are not tested due to restrictions of github actions (no arm runners). The tags of the images have -arm appended to it.
- Arm images can also be built locally.
- Reusable workflow is introduced for building, testing and deploying the images.
This allows the workflow to be reused for other purposes in the future.
- Workflow can be manually triggered. This allows forked Mailu projects to also use the workflow for building images.
- Moved run to bottom of Dockerfile to allow using unmodified / cached states.
- Simplified bash code in deploy.sh.
- Improved the large bash one-liner in CI.yml. It could not handle >9 for 1.x.
Workflow file only triggers if it resides in the branch. If an old PR based on the mailu repo without CI.yml is tested, then the workflow run will not trigger. The merged commit on TESTING/STAGING branch does not contain the required CI.yml workflow file after all. In these cases simply run the workflow manually on the TESTING or STAGING branch,
