This repository holds the index file for the Gruntwork Helm Repository, served using GitHub pages. The index file serves to hold the list of available helm charts distributed by Gruntwork, including the associated metadata that describes the charts. You can read more about the repository index file from the official documentation.

This repository does not contain any of the charts; only references to the charts that are stored in other GitHub repositories. You can find the list of repositories in the Charts section of this document. For information on the reasoning behind this setup, you can refer to the Why are the charts in a different repository? section.

You can access these charts by adding the Gruntwork Helm Repo to your client:

$ helm repo add gruntwork https://helmcharts.gruntwork.io

Then, you can access any of the charts under the gruntwork name. For example, you can find all the Gruntwork charts by searching for gruntwork:

$ helm search gruntwork

In general, each of the charts document the required and optional input values in the corresponding values.yaml file. You can access the values.yaml of a Chart either by inspecting this repository, or using the helm inspect command. For example, to see the values of the k8s-service chart, you can run:

$ helm inspect values gruntwork/k8s-service

Once you know what values the chart requires, you can install the chart by defining your own values.yaml file with the required values defined. Then, you can install the chart to your Kubernetes cluster using helm install:

$ helm install -f values.yaml gruntwork/k8s-service

See the helm install help text for more configuration options.

These charts help you package your applications for deployment into Kubernetes. The code for the charts are available in the gruntwork-io/helm-kubernetes-services github repository.

• k8s-service

The source code for the charts are managed in separate repositories. By storing the charts in separate repositories, we are able to:

• Release and version the charts using GitHub releases. By doing so, we can setup a CI/CD pipeline that automatically generates the chart package with a related index file.
• Make testing easier. By having repositories that only manage a small number of charts, we are able to better test the charts by having faster CI cycles.
• Have examples and documentation that integrates multiple charts together. By having groups of charts under different themed repositories, we are able to provide better examples that require combining multiple charts together.

The index file is automatically deployed from the master branch.

Currently construction of the index file is a manual process. Eventually, this will be enhanced to automatically generate the index file when there is a new release in the source repositories.

To add new charts:

• Release a new version on the source repository containing the helm chart.
• Wait for the CI build to append the index file and chart packages.
• Download the generated index file.
• Merge the index file with the existing one in this repo:
  • If an entry already exists append the list entry to the existing one.
  • For new entries, add to the entries map under the same heading.
