# This step uses [docker/metadata-action](https://github.com/docker/metadata-action#about) to extract tags and
# labels that will be applied to the specified image. The `id` "meta" allows the output of this step to be
# referenced in a subsequent step. The `images` value provides the base name for the tags and labels.

# This step uses the `docker/build-push-action` action to build the image, based on your repository's
# `Dockerfile`. If the build succeeds, it pushes the image to GitHub Packages.
# It uses the `context` parameter to define the build's context as the set of files located in the specified path.
# For more information, see "[Usage](https://github.com/docker/build-push-action#usage)" in the README of the
# `docker/build-push-action` repository.
# It uses the `tags` and `labels` parameters to tag and label the image with the output from the "meta" step.
