Dagger's approach to building CI/CD pipelines is unique, allowing developers to develop their pipelines as code in a programming language they already know, and then execute those pipelines as standard OCI containers. This approach offers portability, consistency, and compatibility with the existing Docker ecosystem. It can be particularly beneficial for teams that need to replace monolithic CI dependency images, share data between CI pipelines and application code, or refactor legacy Dockerfiles. A comprehensive guide is available on replacing a Dockerfile with a Dagger pipeline, covering common tasks such as creating a Dagger client in Go, configuring a container, downloading and building source code, setting the entrypoint, publishing to Docker Hub, and testing locally.
