无法从github存储库分支构建docker映像

Question

I have a private GitHub repository containing 2 branches: master and stage . Repository contains a Dockerfile and other files necessary to build a container image. According to the documentation I can specify the branch when calling docker build command.

However, I am able to run:

sudo docker build -t="superimage" https://github.com/organization/repo.git

After this I am asked for my GitHub login and password.

But when I try to run:

https://github.com/organization/repo.git#stage

I am getting:

Error: Got HTTP status code >= 400: 404 Not Found

What am I doing wrong?

According to the changelog ( https://github.com/docker/docker/blob/master/CHANGELOG.md#170-2015-06-16 ) the building of specific git branches appears to be a feature introduced in 1.7. You'll need to upgrade to 1.7+ to get this functionality.
