Related to this, so pardon my pitch: We [Azure] literally just launched Azure Container Registry Build. [1]

With one command you can build your container in the cloud and have it stored in your registry. Either push the source code from local or have it use a remote git repository.

> $ az acr build --registry $ACR_NAME --image $IMAGE_NAME:$TAG_NAME --context .
