A GitHub Action that builds and publishes Docker images to registries using Git branches as tags.
Publish-Docker-Github-Action is a GitHub Action that automates building and publishing Docker images to container registries as part of CI/CD pipelines. It solves the problem of manually managing Docker image builds and pushes by integrating directly into GitHub workflows, using Git branches for automatic tagging and supporting various registries and advanced build options.
Developers and DevOps engineers using GitHub Actions for CI/CD who need to automate Docker image builds and publications to registries like Docker Hub, GitHub Container Registry, or custom registries.
Developers choose this action for its simplicity, flexibility, and deep integration with GitHub Actions. It reduces pipeline complexity with automatic branch-based tagging, supports advanced features like multi-platform builds and caching, and is widely trusted in the community with extensive configuration options for production use.
A Github Action used to build and publish Docker images
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Automatically uses Git branch names for Docker tags, with the master branch published as 'latest', simplifying CI/CD setup and reducing manual configuration.
Supports publishing to Docker Hub, GitHub Container Registry, and custom registries with easy authentication via secrets, as shown in the README examples.
Offers options for custom tags, semantic versioning tags, and snapshot tags with timestamps, enabling robust and automated versioning strategies.
Allows specifying Dockerfile, build context, working directory, build arguments, and build options, catering to complex image build requirements.
The caching feature requires careful handling to avoid stale packages, with the README warning about periodic rebuilds and potential non-reproducible builds.
Using tag_names or tag_semver can lead to images being overridden by branches with the same name, with no restoration method, as cautioned in the README.
Multi-platform builds necessitate prior setup of docker/setup-buildx-action, adding an extra step and potential integration overhead.
