Hi @ceastman-ibm,

Currently, IBM Cloud Kubernetes Service has some limitations regarding non-root containers and persistent storage permissions.

You can read more about the issues and the possible workarounds here:

I'm getting the same error on minikube using the instructions at https://github.com/Senzing/kubernetes-demo/blob/master/docs/helm-kafka-postgresql/README.md. Specifically, it fails on this step: https://github.com/Senzing/kubernetes-demo/blob/master/docs/helm-kafka-postgresql/README.md#install-postgresql-helm-chart

The instructions worked about 2 weeks ago, so I'm suspecting a recent change.

Note: I also experienced a similar error with bitnami/rabbitmq Helm chart yesterday. Again, that chart worked 2 weeks ago.

I opened bitnami/charts#1210

[tompizmor]

@docktermj I don't think the issue is the same. By default, the postgressql chart should work in Minikube so better to handle your case in the issue you opened in the Bitnami repo.
