# Custom Git Hooks
|
|
|
|
|
|
|
|
|
|
**Note: Custom git hooks must be configured on the filesystem of the GitLab
|
|
|
|
|
server. Only GitLab server administrators will be able to complete these tasks.
|
|
|
|
|
Please explore webhooks as an option if you do not have filesystem access.**
|
|
|
|
|
|
|
|
|
|
Git natively supports hooks that are executed on different actions.
|
|
|
|
|
Examples of server-side git hooks include pre-receive, post-receive, and update.
|
|
|
|
|

for more information about each hook type.

|
|
|
|
|
|
As of gitlab-shell version 2.2.0 (which requires GitLab 7.5+), GitLab
|
|
|
|
|
administrators can add custom git hooks to any GitLab project.
|
|
|
|
|
|
|
|
|
|
## Setup
|
|
|
|
|
|
|
|
|
|
Normally, git hooks are placed in the repository or project's `hooks` directory.
|
|
|
|
|
GitLab creates a symlink from each project's `hooks` directory to the
|
|
|
|
|
gitlab-shell `hooks` directory for ease of maintenance between gitlab-shell
|
|
|
|
|
upgrades. As such, custom hooks are implemented a little differently. Behavior
|
|
|
|
|
is exactly the same once the hook is created, though. Follow these steps to
|
|
|
|
|
set up a custom hook.
|
|
|
|
|
|
|
|
|
|
1. Pick a project that needs a custom git hook.
|
|
|
|
|
1. On the GitLab server, navigate to the project's repository directory.

For an installation from source the path is usually
|
2014-11-07 13:18:00 -05:00
|
|
|
`/home/git/repositories/<group>/<project>.git`. For Omnibus installs the path is
|
|
|
|
|
usually `/var/opt/gitlab/git-data/repositories/<group>/<project>.git`.
|
|
|
|
|
1. Create a new directory in this location called `custom_hooks`.
|
|
|
|
|
1. Inside the new `custom_hooks` directory, create a file with a name matching
|
|
|
|
|
the hook type. For a pre-receive hook the file name should be `pre-receive` with
|
|
|
|
|
no extension.
|
|
|
|
|
1. Make the hook file executable and make sure it's owned by git.
|
|
|
|
|
1. Write the code to make the git hook function as expected. Hooks can be
|
|
|
|
|
in any language. Ensure the 'shebang' at the top properly reflects the language
|
|
|
|
|
type. For example, if the script is in Ruby the shebang will probably be
|
|
|
|
|
`#!/usr/bin/env ruby`.
|
|
|
|
|
|
|
|
|
|
That's it! Assuming the hook code is properly implemented the hook will fire
|
|
|
|
|
as appropriate.
