Git auto-updating container

Image: corfr/git-autoupdate

This image:

• takes a GIT_URL, that it clones and expose as a volume (/git)
• polls from the git remote periodically

Arguments:

• GIT_URL: provided as this to git clone
• POLLING_FREQ: polling frequency as given to cron, something like "*/5 * * * *", default to 5 minutes
• SSH_KEY: can be used to provide an SSH key to authenticate against remote repository
• VOLUME_PATH: if you're not happy with the default volume /git

Warning:

• SSH_KEY expect as base64'd string
• In case URL is ssh (ssh:// or git@), the image will automatically accept the remote key.

For instance you can deploy this as a systemd unit to serve an always up-to-date repository to other services.

Sample usages:

• HTTP repository:

docker run \
            --rm \
            --name legato-docs
            -e GIT_URL=https://github.com/legatoproject/legato-docs.git \
            corfr/git-autoupdate

• SSH repository:

docker run \
            --rm \
            --name legato-docs
            -e [email protected]:legatoproject/legato-docs.git \
            -e SSH_KEY="$(cat ~/.ssh/id_rsa | base64)" \
            corfr/git-autoupdate

• Expose repository as another name:

docker run \
            --rm \
            --name legato-docs
            -e GIT_URL=https://github.com/legatoproject/legato-docs.git \
            -e VOLUME_PATH=/legato-docs \
            -v /legato-docs \
