Rewrite Cobbler's clogger.py module to be a wrapper for the Python stdlib logging.Logger class while keeping almost the same behavior. Add in a format that provides more traceback information. Note line #39 should be super(Logger, self).__init__(__name__, level) but I was getting a weird exception I did not want to dig into.

Python standard logging doesn't super-intelligent and won't expose filehandles,
which we want. So we're not using it.

This gist has files that are used to automate chef repository submodules used for roles, data bags, cookbooks and environments, ultimately uploading the maintained chef repository to chef via knife using Jenkins and Github.

The files in this gist are for having Jenkins automatically manage a chef repository using git submodules. This allows for clean, clutter free management of individual cookbooks, and individual respositories for roles, environments and data bags in our chef-repo.

The process relies on using Github (we use Github Enterprise) and Jenkins in combination with the Jenkins Github plugin to notify Jenkins when a repository has changed.

Our chef-repo directory looks something like:

chef-repo
    - cookbooks
          - Each cookbook is a git submodule managed by Jenkins
    - data_bags (git submodule managed by Jenkins)
