dynamically configure an HTCondor node from a git repository
Project description
Hook to dynamically configure an HTCondor node from a git repository.
Hook Overview
The hook is integrated into a Condor config file to perform the following workflow:
Fetch a git repository to a local cache
Use patterns to select configuration files
Dynamically include configuration in condor
To integrate the hook, use the include command syntax in any HTCondor config file:
include command : condor-git-config https://git.mydomain.com/condor-repos/condor-configs.gitUsage Notes
The hook requires at least Python 3.3 to run.
Installation
Installation provides the condor-git-config executable. All other dependencies are installed automatically.
Stable release version
pip3 install condor_git_configCurrent development version
git clone https://github.com/maxfischer2781/condor-git-config.git
./condor-git-config/setup.py installArgument Files
The condor-git-config executable can use the @ [prefix character](https://docs.python.org/3/library/argparse.html#fromfile-prefix-chars) to read arguments from files. This allows you to prepare options externally
echo $(hostname -d) >> /etc/mycloud/domainand have them used dynamically to adjust configuration
include command : condor-git-config --branch @/etc/mycloud/domain -- https://git.mydomain.com/condor-repos/condor-configs.gitConfiguration Recursion
By default, condor-git-config will not recurse into sub-directories. This allows you to have additional configuration, which is conditionally integrated. For example, consider the following git repository tree:
|- commong.cfg
|- security.cfg
|- aaaron-cloud.cfg
|- aaaron-cloud/
| |- overwrites.cfg
| |- proxy.cfg
|- beebee-cloud.cfgThe aaaron-cloud folder will be ignored by default. You can conditionally include the *-cloud.cfg files like this:
--blacklist '.-cloud\.cfg' --whitelist @/etc/mycloud/flavourThis allows you to further include the files in aaaron-cloud by using include in aaaron-cloud.cfg:
# aaaron-cloud.cfg
include : $(GIT_CONFIG_CACHE_PATH)/overwrites.cfg
include : $(GIT_CONFIG_CACHE_PATH)/proxy.cfgRelease history Release notifications | RSS feed
