| # This workflow is for building and possibly pushing the docker image for | |
| # a commit tagged by a version number. It is triggered either manually or by | |
| # a tag event of type "v*.*.*", which is intended for new releases. Currently, | |
| # pushing to ghcr.io can happen only to commits tagged by a version number. This | |
| # is intended to associate every docker image with a version number. This means | |
| # that there is no option to push the image for the latest commit, even though | |
| # we can build the image for testing purposes. | |
| # | |
| # Manual trigger | |
| # In Actions, go to "Docker image build" and click | |
| # "Run workflow" and choose from the following options. | |
| # Options: | |
| # - 'Build latest commit': for testing for the latest commit | |
| # - 'Build existing version': for testing a particular version | |
| # - 'Build + push existing version': for publishing a particular version | |
| # | |
| # Tag event | |
| # In a tag event of type "v*.*.*", such as new release or retagging, this work | |
| # flow is triggered to build and publish the image for the tagged version | |
| # number. | |
| # | |
| # The image can be pulled by one of the following commands. | |
| # | |
| # docker pull ghcr.io/smithlabcode/dnmtools:latest | |
| # docker pull ghcr.io/smithlabcode/dnmtools:<7-DIGIT SHA> | |
| # docker pull ghcr.io/smithlabcode/dnmtools:v<VERSION NUMBER> (e.g. v1.3.0) | |
