Lens: Deploying Prometheus with Lens reports errors

[bhechinger]

Describe the bug
I've clicked on the Install button for metrics to have Lens deploy Prometheus. It does seem to be working as I do get metrics data in Lens now, however the StatefulSet for Prometheus is in a constant state of alarm with the following error:

create Pod prometheus-0 in StatefulSet prometheus failed error: pods "prometheus-0" is forbidden: error looking up service account lens-metrics/prometheus: serviceaccount "prometheus" not found

To Reproduce
Steps to reproduce the behavior:

1. Go to settings
2. Click on Install for Metrics
3. Go to StatefulSets
4. See error

Expected behavior
Prometheus to deploy without errors.

Environment (please complete the following information):

• Lens Version: 2.1.2
• OS: Ubuntu Studio 19.10
• Installation method: snap
• Kubernetes Cluster: 1.15.3 Digital Ocean Hosted

Kubeconfig:

I checked in on it this morning and the error has gone away?

hmm, makes me think that the StatefullSet might have gotten deployed before the related ServiceAccount. Essentially the deployment happens as kubectl apply -f bunch-of-yamls/ under the hood. This is quite common and as you saw, k8s eventually manages to get everything running. Although usually it should take only max few minutes as all the objects are created within seconds.

Please re-open... the ServiceAccount is there but still shows this error.

had same issue, but waiting 2-5 minutes (during the time found this 😅) resolves the issue for me
