Building and Pushing Docker Images with Taskcluster-Github

Because we're going to be building Docker images it makes sense to use Taskcluster's image_builder Docker image as well as enabling the docker-in-docker feature. Because of this, any Tasks created for as a result of pushes to that branch in that repository and branch may assign the scopes that Role has - like we did above in the "scopes" section of the Task. docker tag mozilla/balrog:${branch_tag} "mozilla/balrog:${date_tag}" docker login -e $dockerhub_email -u $dockerhub_username -p $dockerhub_password docker push mozilla/balrog:${branch_tag} docker push mozilla/balrog:${date_tag}
