This is a pair of git hooks that I use on my gitolite server that facilitate a few interesting things:
You can embed little scripts inside the config, specific to each repo. Each script will be invoked once for every branch with an optional regex filter. For example:
repo testing
config hooks.pre = "some_pre_command.sh"
config hooks.pre.filter = "master$"
config hooks.post = "some_post_command.sh"
config hooks.post.filter = "master$"
Gitolite has a sophisticated mirroring system built in for mirroring between muliple gitolite instances. This
doesn't really help when you want to push to Github or S3. To set up a mirror, create a config key for that
repo named mirror.<name> with the value set to the remote URL.
repo testing
config mirrors.github = "git@github.com:example/testing.git"
config mirrors.s3 = "amazon-s3://.jgit@bugsplat-git-repos/testing.git"
config mirrors.other = "user@example.com:example/testing.git"
To push to S3 you'll need to create a bucket on S3 and create a file in the gitolite user's home directory that contains your access key and secret key in this format:
accesskey: YOUR-AWS-ACCESS-KEY
secretkey: YOUR-AWS-SECRET-KEY
Your mirror URL will then be in the format amazon-s3://<filename>@<s3-bucket-name>/<repo_name>.git.
In the example above, the key file is at $GITOLITE_HOME/.jgit.
Sometimes it's really useful to have a local clone of a particular repository. These hooks let you do that
by setting a config entry named hooks.clone.path to the path where the clone should exist. Note that any
changes made to this clone will be erased the next time you push.
repo testing
config hooks.clone.path = "/var/repos/testing"
Copy pre-receive and post-receive to $GITOLITE_HOME/.gitolite/hooks/common and make sure they're executable.
Copy jgit to $GITOLITE_HOME/bin/jgit. Customize the constant REPO_BASE at the top of post-receive to point
the correct location for your system.
