Error while deploying Single-node Network Edge cluster

[amitinfo2k]

Hello,

I am trying to deploy a single-node Network Edge cluster (using command ./deploy_ne.sh -f minimal single). It's failing while waiting for Grafana pod.

TASK [telemetry/grafana : wait for Grafana pod to be ready] ****************************************************************************
task path: /home/centos/openness-experience-kits/roles/telemetry/grafana/tasks/main.yml:205
fatal: [controller]: FAILED! => {

        "--namespace=telemetry",
        "--for=condition=Ready",
        "pods",
        "--timeout=600s"
    ],

}

STDERR:

For Graphana pod I see following error:

Hi, Could you provide output from kubectl describe pod grafana_pod_name command?

[amitinfo2k]

I don't have the complete o/p now, but the snippet is below:

Normal   Created     30m (x2 over 32m)    kubelet, openness  Created container grafana-sc-datasources
Warning  Failed      28m (x2 over 30m)    kubelet, openness  Error: context deadline exceeded

Well, with this limited output there's not much we can do to help you. Maybe try deploy it one more time and check if error occurs again, if it does please provide output from following commands: kubectl describe po grafana-pod_name -n telemetry kubectl logs grafana-pod_name -n telemetry - c grafana-sc-datasources
