Docker image for Google Copybara. Uses upstream weekly snapshot releases and keeps the default Docker workflow simple.

docker run --rm -it \
  -v "$(pwd)":/usr/src/app \
  dockette/copybara:latest

This runs the default command:

copybara migrate copy.bara.sky

Java 21, Copybara, git, Mercurial, Quilt, OpenSSH client, buildifier, buildozer.

Run Copybara directly with your own arguments:

docker run --rm -it \
  -v "$(pwd)":/usr/src/app \
  dockette/copybara:latest validate copy.bara.sky

The image supports the same COPYBARA_* environment variables as the upstream Docker wrapper.

docker run --rm -it \
  -e COPYBARA_SUBCOMMAND=validate \
  -e COPYBARA_CONFIG=copy.bara.sky \
  -e COPYBARA_WORKFLOW=default \
  -v "$(pwd)":/usr/src/app \
  dockette/copybara:latest

Supported variables:

• COPYBARA_SUBCOMMAND
• COPYBARA_CONFIG
• COPYBARA_WORKFLOW
• COPYBARA_SOURCEREF
• COPYBARA_OPTIONS

If your origin or destination uses SSH, mount your git config, SSH directory, and SSH agent socket:

docker run --rm -it \
  -v ~/.gitconfig:/root/.gitconfig:ro \
  -v ~/.ssh:/root/.ssh \
  -v ${SSH_AUTH_SOCK}:${SSH_AUTH_SOCK} \
  -e SSH_AUTH_SOCK=${SSH_AUTH_SOCK} \
  -v "$(pwd)":/usr/src/app \
  dockette/copybara:latest

• The image follows upstream guidance and ships the prebuilt weekly snapshot jar.
• Copybara expects your config file, such as copy.bara.sky, to be available inside /usr/src/app.
• Snapshot versions can be updated by changing COPYBARA_VERSION and COPYBARA_SHA256 in latest/Dockerfile.
