Overview
========
The OpenStack git repositories are hosted on this server and served up via
https using cgit and via git:// by git-daemon.
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.
Apache is running on a CentOS 6 system with the EPEL repository that includes
the cgit package. SELinux is enabled and requires restorecon to be run against
/var/lib/git to set the appropriate SELinux security context, this is handled
by puppet.
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 from the Gerrit server.
