docker build -t ${package}:${GIT_COMMIT}
docker tag ${package}:${GIT_COMMIT} ${package}:unstable
During the first docker build
docker tag ${package}:${GIT_COMMIT} ${package}:stable
docker push ${package}:${GIT_COMMIT} docker push ${package}:stable
After the tests pass
docker tag ${package}:${GIT_COMMIT} ${package}:live
docker push ${package}:live
After deployment succeeds
