The web frontend cgit is running on


The OpenStack git repositories are hosted on a pool of CentOS servers with the EPEL repository that includes the cgit package. They are served up via https using cgit and via git:// by git-daemon behind HAProxy which handles load balancing across the nodes.

SELinux is enabled on these nodes and requires restorecon to be run against /var/lib/git to set the appropriate SELinux security context. SELinux rules are also in place to allow for Apache to run on a non-standard port so it can sit behind HAProxy. This is all handled by puppet.

In order to mitigate potential problems with HTTP(S) responses, HAProxy is configured using the source balance method so that every request from a single host will be served by one backend node unless nodes are added or removed.

The jeepyb script create-cgitrepos runs against projects.yaml to generate the /etc/cgitrepos file listing all the git repositories. The git repositories are synced to all the nodes from the Gerrit server.
