A useful simple git container running in alpine Linux, especially for tiny Linux distro, such as RancherOS, which doesn't have a package manager.

https://travis-ci.org/alpine-docker/git

https://hub.docker.com/r/alpine/git/tags/

Notes:

New tags with non-root user in image has been created.

alpine/git:<version>-user
alpine/git:user

Its uid and gid in container are 1000

$ docker run -ti --rm --entrypoint=id alpine/git:user
uid=1000(git-user) gid=1000(git-user)

Docker build from feature branch feature/non-root

docker run -ti --rm -v ${HOME}:/root -v $(pwd):/git alpine/git <git_command>

For example, if you need clone this repository, you can run

docker run -ti --rm -v ${HOME}:/root -v $(pwd):/git alpine/git clone https://github.com/alpine-docker/git.git

To save your type, add this fuction to ~/.bashrc or ~/.profile

$ cat ~/.profile

...

function git () {
    (docker run -ti --rm -v ${HOME}:/root -v $(pwd):/git alpine/git "$@")
}

...

$ source ~/.profile

for example, if you need clone this repository, with the function you just set, you can run it as local command

git clone https://github.com/alpine-docker/git.git

alias git="docker run -ti --rm -v $(pwd):/git -v $HOME/.ssh:/root/.ssh alpine/git"

• You need redefine (re-run) the alias, when you switch between different repositories
• You need run above alias command only under git repository's root directory.

$ cd application
$ alias git="docker run -ti --rm -v $(pwd):/git -v $HOME/.ssh:/root/.ssh alpine/git"
$ git clone [email protected]:YOUR_ACCOUNT/YOUR_REPO.git
$ cd YOUR_REPO
$ alias git="docker run -ti --rm -v $(pwd):/git -v $HOME/.ssh:/root/.ssh alpine/git"
# edit several files
$ git add . 
$ git status
$ git commit -m "test"
$ git push -u origin master

Supports git, http/https and ssh protocols.
