I have tied different solutions online, none worked.

helm install --name realtesting stable/postgresql --debug

The expect result is a deployed postgresql on my kubernetes cluster

Please help!

It seems that you have not initialized helm with a service account.

In rbac-config.yaml:

apiVersion: v1
kind: ServiceAccount
metadata:
  name: tiller
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: tiller
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
  - kind: ServiceAccount
    name: tiller
    namespace: kube-system

Step 1: kubectl apply -f rbac-config.yaml

Step 2: helm init --service-account tiller --history-max 200

Step 3: Test the setup with heml ls. There would not be any output from running this command and that is expected. Now, you can run helm install --name realtesting stable/postgresql

you need to deploy the tiller server.

then follow the below steps

master $ kubectl get po -n kube-system |grep tiller
tiller-deploy-5bcf6f5c7c-km8hn   1/1       Running   0          18s

master $ helm install --name realtesting stable/postgresql --debug
