Daffodil release artifacts are built using GitHub actions. This container can be used to build those same artifacts for testing or verifying reproducibility. This can be used for all Daffodil projects, including the Daffodil VS Code Extension and the SBT plugin.
To build or update the build release container image:
podman build -t daffodil-build-release containers/build-release/
To use the container image to build a release, run the following from the root of the project git repository, replacing <REPO_DIR> with the path to the git repository of the project to build and <ARTIFACT_DIR> with the directory where you want the artifacts saved:
podman run -it --rm \ --hostname daffodil.build \ --volume <REPO_DIR>:/project:O \ --volume <ARTIFACT_DIR>:/artifacts \ daffodil-build-release
Note that the <REPO_DIR> volume uses the :O suffix so that changes to the repository inside the container do not affect the repository outside the container.
When run, the container will ask for an optional pre-release label (e.g. rc1) and the project to build. The resulting artifacts will be written to the <ARTIFACT_DIR>/release/ directory.
