Helm Charts

For deployment on Kubernetes OpenG2P provides Helm charts for all its components. Instructions to install a module/component using Helm are provided in the respective deployment guides.

Source code

Charts may be found here:

Published repository

All charts are published to this public website: https://openg2p.github.io/openg2p-helm. This website is automatically created by Github with contents on gh-pages branch of openg2p-helm repository. Charts are automatically published via Github action given here. The publishing process involves the following steps:

  1. Create Helm packaged zip files.

  2. Check-in the packaged zip in gh-pages branch of openg2p-helm repository.

Charts may be published manually with the procedure given below:

  1. Create Helm packaged zip files by executing the following command in the folder that contains your charts source code.

helm package charts/<chart name>
  1. You will see packaged .tgz files created in the current directory.

  2. Clone https://github.com/OpenG2P/openg2p-helm repo and switch to gh-pages branch. Copy the above .tgz files to root folder of the repo (where you will see several .tgz files).

  3. Make sure you have direct check-in permissions to the openg2p-helm repo.

  4. Run


Publish Helm charts as Rancher apps

To have your charts available in Rancher Apps and be able to install from Rancher UI follow guide given here. See example of Helm chart configured for Rancher.

To publish a chart on Rancher Apps in step 3 above, copy the chart zip to /rancher folder of the repo. Run ./index.sh.This will generate and index.yaml file in the folder. This file will be read by Rancher to display in the catalogue (refer Installation using Rancher UI on how to add this repository).

If in annotations for the chart fixed name and namespace of the Helm chart is specified, then only one instance of the application will be installed and further attempts to install will only update the application. Example, Monitoring app on Rancher.

Helm chart versions

The chart version is mentioned as version attribute in the Chart.yaml file (see example). For version numbers we adhere to Semantic Versioning 2.0 with "Simple 1-1 versioning" convention as described here. Here, chart version is kept same as docker version (app version).

Same as chart version




Since chart version matches docker version (app version) it is recommended that appVersion attribute is removed from Chart.yaml as it is redundant.
