I am simply trying to deploy this Grafana app as-is, no changes to the YAML have been made: https://grafana.com/docs/grafana/latest/setup-grafana/installation/kubernetes/
VMs are Ubuntu 20.04 LTS. The Kubernetes cluster is made up of the Control-Plane/Mstr & 3x Worker nodes:
root@k8s-master:~# kubectl get nodes
NAME STATUS ROLES AGE VERSION
k8s-master Ready control-plane 35d v1.24.2
k8s-worker1 Ready worker 4h24m v1.24.2
k8s-worker2 Ready worker 4h24m v1.24.2
k8s-worker3 Ready worker 4h24m v1.24.2v
Other K8s Pods such as NGINX run without issue.
However, the Grafana pod cannot start and is stuck in a Pending state:
root@k8s-master:~# kubectl create -f grafana.yaml
persistentvolumeclaim/grafana-pvc created
deployment.apps/grafana created
service/grafana created
# time passed here...
root@k8s-master:~# kubectl get pods
NAME READY STATUS RESTARTS AGE
grafana-9bd5bbd6b-k7ljz 0/1 Pending 0 3h39m
Troubleshooting this, I found there is an issue with the storage PersistentVolumeClaim (the pvc):
root@k8s-master:~# kubectl get pvc
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
grafana-pvc Pending 2m22s
root@k8s-master:~#
