| # 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. | |
