If enjoy, please consider buying me a coffee.

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

This feature was added on 23th May 2021.

1. Version v2.30.2 and 1.0.30 are manually pushed by me with multi-arch image supported
2. Older version will be not updated as multi-arch images
3. Newer vesions from now on will be multi-arch images (--platform linux/amd64,linux/arm/v7,linux/arm64/v8,linux/arm/v6,linux/ppc64le,linux/s390x,linux/386)
4. I don't support other architectures, except amd64, because I have no other environment to do that. If you have any issues with other arch, you need raise PR to fix it.
5. There would be no difference for docker pull , docker run command with other arch, you can run it as normal. For example, if you need pull image from arm (such as new Mac M1 chip), you can run docker pull alpine/git:v2.30.2 to get the image directly.

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.

alias git='docker run -ti --rm -u$(id -u):$(id -g) -e HOME=${HOME} -v /etc/passwd:/etc/passwd -v /etc/group:/etc/group -v ${HOME}:${HOME} -v $(pwd):/git alpine/git'

• set uid:gid and provide passwd and group from host
• run git as the current user instead of root for proper ownership of files
• can be used at any directory as evaluation of $(pwd) is defered until alias is used

$ cd application
$ alias git="docker run -ti --rm -v $(pwd):/git -v $HOME/.ssh:/root/.ssh alpine/git"
$ git clone git@github.com: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.

Set CI to run builds every month.

• build latest alpine image locally
• Get the git version from the image
• use the git's version as image tag as well (v${GIT_VERSION})
• update latest tag for this image
