heluxup makes it easy to upgrade HelmRelease objects in a flux control respository.

Project description

heluxup

By using the flux helm operator it is possible to manage helm charts in a git repository and flux takes care of the deployment.

heluxup is able to parse the flux control repository for HelmReleases and checks if updates of the charts are available. If updates are available heluxup updates the yaml files in the flux control respositroy accordingly. (It is possible to pass --dry-run to check the changes without modifying any files.)

Installation

Simply install heluxup with pip

$ pip install heluxup

or clone the repository

$ git clone git@github.com:ekeih/heluxup.git
$ cd heluxup
$ pip install -e .

Usage

$ heluxup /home/max/repos/flux-control/
