Using Helm charts

How to use Helm charts with your Release instances

Using Helm charts on your instances

Helm is a package manager for Kubernetes. Helm charts are used to describe related collections of Kubernetes resources. You can use Helm with Release.

You can configure Helm by adding a values.yaml file to your project repository. As an example, you can see our Helm Ingress repository on GitHub, which configures a Helm chart for generating an ingress for your application.

Viewing the instances deployed by Helm

One Helm chart might deploy several instances. You can see these in the same way that you view other instances in an environment. Visit your environment and scroll down on the "Details" page to see all your running instances, including those deployed by Helm.

Viewing Helm charts directly on your Release cluster

If you want to view the Helm charts that are deployed to your Release cluster, download and configure Kubectl on your local machine. This will give you access to the helm command, which you can use to see your deployed charts, for example:

helm list

and

helm get all jenkins -n jenkins

Injecting Release environment variables into your Helm charts

You can inject any environment variables defined in your Release configuration into your Helm values.yaml file. Here's an example:

web:
  image:
    repository: ${RELEASE_REGISTRY_PATH}
    name: web@sha256
    tag: ${WEB_REGISTRY_IMAGE_SHA}
  hostname: ${WEB_INGRESS_HOST}
  url: "jdbc:postgresql://${WEB_RDS_DB_POOL_HOST}:5432/web"
