How to build docker image from github repository
docker build url#ref:dir
Git URLs accept context configuration in their fragment section,separated by a colon :. The first part represents the reference thatGit will check out, this can be either a branch, a tag, or a commitSHA. The second part represents a subdirectory inside the repositorythat will be used as a build context.
For example, run this command to use a directory called docker in thebranch container:
docker build https://github.com/docker/rootfs.git#container:docker
The thing you specified as repo URL is not a valid git repository. You will get error when you will try
git clone github.com/docker-library/redis/tree/99c172e82ed81af441e13dd48dda2729e19493bc/2.8.10
Valid URL for this repo is github.com/docker-library/redis
. So you may want to try following:
docker build github.com/docker-library/redis
But this will not work too. To build from github, docker requires Dockerfile
in repository root, howerer, this repo doesn't provide this one. So, I suggest, you only have to clone this repo and build image using local Dockerfile.
