Daniel P. Berrangé b157bf46c9 docs: list settings required in creating a new git repo 
The libvirt project has alot of git repositories, and they must all be
configured in the same way, more or less. This page documents the
settings changes that I have made in GitLab and GitHub when configuring
projects, both as a reminder for myself, and to help anyone else doing
the same in future. Also included is info about the repo mirroring on
the libvirt.org server.

In the master git repository create a file .github/lockdown.yml to restrict use of issue tracker and pull requests.

libvirt.org

The libvirt project server hosts read-only mirrors of all the libvirt Git repositories in the directory /data/git.

When creating a new repository the following steps are required:

  • Create repo with :

    $ sudo su -
# cd /data/git
# mkdir $repo.git
# cd $repo.git
# git init --bare
# touch export
# touch git-daemon-export-ok
# cd ..
# chown -R gitmirror.gitmirror $repo.git
# chmod -R g+w $repo.git
# find -type d $repo.git | xargs chmod g+s

  • Set the description and config files following other repos' example

  • Setup mirroring :

    $ sudo su - gitmirror
# ./newrepo.sh /data/git/$repo.git
# cd mirrors
# $HOME/sync-one.sh $repo.git
