Helm charts

Usage

Helm must be installed to use the charts. Please refer to Helm's documentation to get started.

Once Helm is set up properly, add the repo as follows:

helm repo add vikaspogu https://vikaspogu.dev/helm-charts/

You can then run helm search repo vikaspogu to see the charts.

GitHub Actions

Chart Release Action

This repo uses chart-releaser Action to host helm charts on master branch

Setup

• A GitHub repo containing a directory with your Helm charts (eg: /charts)
• A GitHub branch called gh-pages to store the published charts

  git checkout --orphan gh-pages
  git rm -rf .
  git commit -m "Initial commit" --allow-empty
  git push

• Create a workflow .yml file in your .github/workflows directory
• Create a secret in your repository, CR_TOKEN, which contains a GitHub personal access token with repo scope

Example Workflow

Create a workflow (eg: .github/workflows/release.yml):

name: Release Charts

  push:
    branches:
