BASH script to clone all git repository in a Group on GitLab, or Organization on GitHub.
Introduction
Starting at a new employer always mean checking out various git repositories.
As the amount of repositories a company has grows, the time needed to clone all of those repositories also grows.
This script automates this task.
In order for this script to work, a personal access token
is needed.
To avoid unexpected behaviour, use Group's ID, rather than its key/name. Informations about Groups can be found in the API at
https://gitlab.example.com/api/v4/groups.
Usage
Call bash gitlab-clone-projects.sh <gitlab-domain> <group-name> <gitlab-token>
For full usage details gitlab-clone-projects --help is available:
Usage: gitlab-clone-projects.sh [-dh] <gitlab-domain> <group-id> <gitlab-token>
Where:
<gitlab-domain>is the domain where gitlab lives (for instance: 'gitlab.com')<group-id>is the ID of the group who's repos should be cloned<gitlab-token>is the API access token to make REST API calls with
Options:
- -d|--dry-run Only list the repositories, without actually cloning them
- -h|--help Print this help dialogue and exit
- -u|--user The given ID is a user, not a group
The repositories will be cloned into a sub-directory under the path from Where
this script has been called. The repository will be cloned into ./${group-id}/${repo-name}
The git executable can be overridden by setting the GIT environmental variable
before calling this script:
GIT=/usr/local/git-plus gitlab-clone-projects.sh <gitlab-domain> <group-id> <gitlab-token>
github-clone-projects.bash
