Using Helm with Tanzu Kubernetes Grid Integrated Edition
Note: As of v1.8, Enterprise PKS has been renamed to VMware Tanzu Kubernetes Grid Integrated Edition. Some screenshots in this documentation do not yet reflect the change.
Page last updated:
Helm 3 requires less configuration than Helm 2.
Helm 3 and Helm 2 include the following components:
||Client||Runs on your local workstation|
||Server||Runs inside your Kubernetes cluster|
Helm packages are called charts. For more information, see Charts in the Helm documentation.
Examples of charts:
For more charts, see the Helm Charts repository on GitHub.
To install and configure Helm 3, follow the Step 1: Install And Configure Helm instructions in the Bitnami TKGI documentation.
To use Helm 2 with Tanzu Kubernetes Grid Integrated Edition, you must first configure the Tiller component to give it access to the Kubernetes API. Tiller runs inside the Kubernetes cluster.
To grant API access to Tiller and install Helm 2:
Create a role-based access control (RBAC) configuration file named
rbac-config.yamlthat contains the following:
apiVersion: v1 kind: ServiceAccount metadata: name: tiller namespace: kube-system --- apiVersion: rbac.authorization.k8s.io/v1beta1 kind: ClusterRoleBinding metadata: name: tiller roleRef: apiGroup: rbac.authorization.k8s.io kind: ClusterRole name: cluster-admin subjects: - kind: ServiceAccount name: tiller namespace: kube-system
Create the service account and role by running the following command:
kubectl create -f rbac-config.yaml
Download and install the latest v2 patch release of the Helm CLI.
Deploy Helm 2 using the service account by running the following command:
helm init --service-account tiller
Verify that the permissions are configured by running the following command:
There should be no output from the above command.
To apply more granular permissions to the Tiller service account, see the Helm RBAC documentation.
