Bitbucket Pipeline makes available the environment variable `BITBUCKET_COMMIT` which contains the commit hash of a commit that kicked off the build. My build requires additional metadata about this git commit, because we build a version string based off of this metadata like so
REVISION = "$(TZ=UTC git show -s --format=%cd --date=format-local:%Y%m%d-%H%M HEAD).$(git rev-parse --short HEAD)"
Is there a way to configure Bitbucket Pipeline to include this additional variable in the environment? I assume the `.git` directory is available in the build container, so if git were present in the build docker image, I could execute this command in the container - is that right?
