    #   source_version:
    #     The source version as reported by the `bump_version.sh show` command.
    #   tags:
    #     A comma separated list of Docker tags to be applied to the images on
    #     Docker Hub.  The tags will vary depending on:
    #     - The event that triggered the build.
    #     - The branch the build is based upon.
    #     - The git tag the build is based upon.
    #
    #     When a build is based on a git tag of the form `v*.*.*` the image will
    #     be tagged on Docker Hub with multiple levels of version specificity.
    #     For example, a git tag of `v1.2.3+a` will generate Docker tags of
    #     `:1.2.3_a`, `:1.2.3`, `:1.2`, `:1`, and `:latest`.
    #
    #     Builds targeting the default branch will be tagged with `:edge`.
    #
    #     Builds from other branches will be tagged with the branch name. Solidi
    #     (`/` characters - commonly known as slashes) in branch names are
    #     replaced with hyphen-minuses (`-` characters) in the Docker tag.  For
    #     more information about the solidus see these links:
    #       * https://www.compart.com/en/unicode/U+002F
    #       * https://en.wikipedia.org/wiki/Slash_(punctuation)#Encoding
    #
    #     Builds triggered by a push event are tagged with a short hash in the
    #     form: sha-12345678
    #
    #     Builds triggered by a pull request are tagged with the pull request
    #     number in the form pr-123.
    #
    #     Builds triggered using the GitHub GUI (workflow_dispatch) are tagged
    #     with the value specified by the user.
    #
    #     Scheduled builds are tagged with `:nightly`.
