Build stuck in pending status using Drone with kubernetes

I’m using the stable/drone to host Drone on a kubernetes cluster, when I’m triggering a build the job pod is well created but the build is stuck in Pending status, the job pod seems ok from the describe command

Events:
  Type    Reason     Age    From                        Message

  Normal  Created    3m35s  kubelet, srv-1  Created container drone-controller
  Normal  Started    3m34s  kubelet, srv-1  Started container drone-controller

But I have nothing in the pod logs, how can I activate them to debug further?

EDIT
The logs from the job pod after enabling them are stuck with this:

{
  "arch": "amd64",
  "level": "debug",
  "machine": "srv-1",
  "msg": "runner: get stage details from server",
  "os": "linux",
  "stage-id": 1,
  "time": "2019-06-24T09:56:12Z"
}

Thank you

Same issue here - upgraded issue happened after upgrading to the latest drone:1.2.1 tag. Rolling back didn’t fix it.

Any suggestions?

@zfilali take a look at this PR from the upstream charts repo

After upgrading to 1.2.1 I was missing both the DRONE_RPC_PROTO env and the port on the DRONE_RPC_HOST
