Publishing Helm Charts to GitHub Container Registry

So you have a local Helm chart that you want to share with others?

In this quick tutorial, I’ll walk you through the process of publishing Helm charts to your very own Helm repository using GitHub Container Registry and GitHub Pages using GitHub Actions.

Before you begin, make sure you have the following prerequisites:

• A GitHub account
• A GitHub repository with your Helm chart
• GitHub CLI installed on your local machine
• Bash shell

GitHub Pages Setup

We will use GitHub Pages to host the Helm repository. So you will need to create a new branch called gh-pages. This branch will contain the Helm chart binaries and a README.md file with instructions on how to use the helm repo and install its charts.

Publishing Container Images to GitHub Container Registry

Do you have a container image that you want to share with the world? GitHub Container Registry (GHCR) is a great place to store and share your container images. In this tutorial, we’ll show you how to publish container images to GHCR using GitHub Actions.

Start by creating a new repository on GitHub or cloning an existing one. Then make sure you have a Dockerfile in the root of your repository.

Adding a GitHub Codespace button to your README

GitHub Codespaces is a great way to make it easier for people to contribute to your project.

With one line of markdown in your README, you can add a button that looks like this…
