Infrastructure git repository


This repository is a private git repo setup for maintaining server configurations. This also gives us a quick way to rollback changes.

In the future there may be other services that supersede this need, but for now this is a lightweight solution to the problem.


  1. Make the config folder symlink: cd /root/git/ ln -s /path/to/foo-project/config/ ovirt-infra-foo

  2. Change in to the config folder via the symlink, then initiate a git repo: cd ovirt-infra-foo git init

  3. Add one or more files and directories to the repository, then commit the changes: git add * ## Or a specific file or directory git commit -m “Initial commit message.”

  4. Change to the local git root and make a directory for the new git repo: cd /usr/local/git_root/ mkdir ovirt-infra-foo.git

  5. Change to the new directory and initiate the bare repository: cd ovirt-infra-foo.git/ git –bare init

  6. These configurations make sure everything is kept group read/write; merges are disallowed on push; and directory permissions are set: git config core.sharedrepository 1 git config receive.denyNonFastforwards true find objects -type d -exec chmod 02770 {} \;

  7. Change back to the original directory, set the new origin location for tracking, and push up the initial commit: cd /root/git/ovirt-infra-foo git remote add origin /usr/local/git_root/ovirt-infra-foo.git git push origin master

  8. Create local “master” branch that is tracking “origin/master”, switch to the new branch: git checkout origin/master git branch -f master origin/master git checkout master

Note: checking out 'origin/master'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b new_branch_name

HEAD is now at 93777d4... Mailman git only needs the single config file, afaict.
[root@linode01 ovirt-infra-mailman]# git branch -f master origin/master
Branch master set up to track remote branch master from origin.
[root@linode01 ovirt-infra-mailman]# git checkout master
Switched to branch 'master'
