We've been using Docker for Guacamole's Jenkins builds, as well,
autogenerating a Dockerfile which performs the actual build within a
pristine environment.
Not sure how different things would need to be with docker-compose, but we
use a combination of the "trap" command (to ensure cleanup happens
regardless of build result) and the "--no-cache" and "--rm" flags:
# Remove image regardless of build result
export TAG="guac-${BUILD_TAG}"
trap "docker rmi --force $TAG || true" EXIT
# Perform build
docker build --no-cache=true --rm --tag "$TAG" .
