• Clone the repo.

• Build the image:

    docker build -t swiftpm-docker .
  

• Create a shared volume to keep swiftpm builds:

    docker create -v /build --name spm-build swiftpm-docker /bin/true
  

• Build (and test) SwiftPM inside the shared volume:

    docker run -itv $(pwd):/swiftpm --volumes-from spm-build swiftpm-docker /swiftpm/Utilities/bootstrap test --build /build
  

• Run any other package using previously built SwiftPM:

    docker run -itv $(pwd):/pkg --volumes-from spm-build swiftpm-docker /build/debug/swift-build -C /pkg
  

• Delete all containers:

    docker rm $(docker ps -a -q)
  

• List images:

    docker images
  

• Delete images:

    docker rmi <id>
  

Note: Add -d to demonize a container, --rm to remove the container on exit.
