In official docs we can see:
# docker build github.com/creack/docker-firefox
It just works fine to me. docker-firefox is a repository and has Dockerfile within root dir.
Then I want to buid redis image and exact version 2.8.10 :
# docker build github.com/docker-library/redis/tree/99c172e82ed81af441e13dd48dda2729e19493bc/2.8.10
2014/11/05 16:20:32 Error trying to use git: exit status 128 (Initialized empty Git repository in /tmp/docker-build-git067001920/.git/
error: The requested URL returned error: 403 while accessing https://github.com/docker-library/redis/tree/99c172e82ed81af441e13dd48dda2729e19493bc/2.8.10/info/refs
fatal: HTTP request failed
)
I got error above. What's the right format with build docker image from github repos?
docker build uri#ref:dir
Git URLs accept context configuration in their fragment section, separated by a colon :. The first part represents the reference that Git will check out, this can be either a branch, a tag, or a commit SHA. The second part represents a subdirectory inside the repository that will be used as a build context.
For example, run this command to use a directory called docker in the branch container:
docker build https://github.com/docker/rootfs.git#container:docker
