PureStorage Helm Charts

Installation

Adding the pure repo

helm repo add pure https://purestorage.github.io/helm-charts
helm repo update

Helm Setup

Please ensure you have a correct service account with cluster-admin role in K8s/Openshift for Helm.

Install the helm by following the official documents:

  1. For Kubernetes https://docs.helm.sh/using_helm#install-helm

  2. For Openshift https://blog.openshift.com/getting-started-helm-openshift/

In order to enable helm tiller to install any type of services across the entire cluster, it's required to grant helm tiller with cluster admin role.

After helm installation, configure the cluster admin role for the service account of the helm tiller. You need to figure out the correct service account.

# For K8s, for exmaple of a service account {TILLER_NAMESPACE}:default
kubectl create clusterrolebinding add-on-cluster-admin --clusterrole=cluster-admin --serviceaccount=${TILLER_NAMESPACE}:default

# For Openshift:
oc adm policy add-cluster-role-to-user cluster-admin system:serviceaccount:${TILLER_NAMESPACE}:tiller

For more details, please see https://docs.helm.sh/using_helm/

Updating Charts

We serve charts using a github page with its root at ./docs when the helm source is updated we need to do something like:

helm package ./$CHART_NAME
cp $CHART_NAME.tgz ./docs
helm repo index docs --url https://purestorage.github.io/helm-charts

Luckily there is a helper script to make this easy:

./update.sh

You can then commit the changes and have them become available once merged.
