Automatic Builds with GitHub Actions#
GitHub will build Docker containers for you. The resulting built container is available on GitHub’s public repository, which simplifies deployments.

Actions are enabled when you place YAML files in the
.github/workflows directory in the repository. Follow the instructions in GitHub’s Publishing images to GitHub Packages documentation.

Dockerfile from the last lab. Commit it in the root of your CIS-92 repository and push the commit.

$ docker run -it --rm -p 8080:8080 ghcr.io/your-name/repo-name:latest
