Hello

I have tried installing drone server on k8s using latest helm chart(2.5.1) with drone image 1.6.1.  
Following chart’s readme on _github\*com/helm/charts/tree/master/stable/drone_, i use some helm values :

```auto
sourceControl.provider=github 
sourceControl.github.clientID=xxxxxxxxx
sourceControl.secret=drone-gh-secrets 
server.host=xxxxx.webrelay.io

```

Current k8s version is on v1.16.3 and installed on private cluster. So to get public access of drone-server i use [https://webhookrelay.com/](https://webhookrelay.com/) service using its tunnel feature.  
Based on similiar topic about [Drone exec runner fails with “not implemented”](http://discuss.harness.io/t/drone-exec-runner-fails-with-not-implemented/6055), that clarify “not implemented” error is possible to occur when there is reverse proxy or load balancer that could be interfering and redirect POST becomes a GET request in agent and server communication.

So I try run drone runner directly on k8s using kubernetes-drone-runner after experiencing issue on docker runner and exec runner, so i can connect to the server just using k8s service (without additional reverse proxy or loadbalancer).  
Here is my kubernetes runner configuration :

### kubernetes drone runner deployment:

```auto
apiVersion: apps/v1
kind: Deployment
metadata:
  name: drone-runner
  namespace: drone-system
spec:
  ...
        env:
        - name: DRONE_DEBUG
          value: "true"
        - name: DRONE_TRACE
          value: "true"
        - name: DRONE_RPC_HOST
          value: drone-drone.drone-system.svc.cluster.local
        - name: DRONE_RPC_PROTO
          value: http
        - name: DRONE_RPC_SECRET
          valueFrom:
            secretKeyRef:
              name: drone-server-secrets
              key: clientSecret
        - name: DRONE_RPC_DUMP_HTTP
          value: "true"
        - name: DRONE_RPC_DUMP_HTTP_BODY
          value: "true"

```

But its still give same errors :

### drone-runner log

The charts in Helm stable are broken and are not an officially supported installation method. We recommend using [gtaylor/drone-charts](https://github.com/gtaylor/drone-charts) instead, which we plan to adopt as our official charts in the coming weeks.

Ohh, thanks for the information. I think the one on the stable helm chart is official one 🙂

Thanks @ashwilliams1 for the clarification. It works using your suggested chart. Thank you very much.

In my case i am using github source directly to install the charts. As the @ashwilliams1 stated that the chart will be adopted as the official one in coming weeks, so I think `helm repo add drone https://drone.github.io/charts` will fail until its officialy adopted. Maybe you can also try using `helm install drone https://github.com/gtaylor/drone-charts/releases/download/drone-0.1.3/drone-0.1.3.tgz`
