Unable to deploy Minio in kubernetes cluster using Helm - kubernetes

Question

I am trying to deploy minio in kubernetes using helm stable charts,
and when I try to check the status of the release
helm status minio
the pod desired capacity is 4, but current is 0
I tried to look the journalctl logs for any logs from kubelet, but found none
I have attached all helm charts can some one please point out what wrong am I doing?

Answer 1

I suspect you are not getting the physical volume. Check your kube-controller-manager logs on your active master. This will vary depending on the cloud you are using: AWS, GCP, Azure, Openstack, etc. The kube-controller-manager is usually running on a docker container on the master. So you can do something like:
docker logs <kube-controller-manager-container>
Also, check:
kubectl get pvc
kubectl get pv
Hope it helps.

Answer 2

bit more digging gave me the answer, statefulset was deployed but pods were not created
kubectl describe statefulset -n <namespace> minio
the log said it was looking for mount path which was "" (in previous versions of charts), changing it solved my issue.
