| # 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. | |
