Hi all, i am using rancher desktop, I post here as I tried mainly everything I think about, maybe you will have a response... I would like to use postgres, but I have "access issues / Permission denied" when I enable storage... it works fine without it I tried 2 different images (alpine, bulleyes), 2 different StorageClasses (local-path, openESB), with or without securityContext option (maybe I do not find the right one) and my mount point is set (as recommended) to "/var/lib/postgresql/data" and the "PGDATA" variable is set to "/var/lib/postgresql/data/db/" Full configuration files set is available here : https://github.com/sorriso/kube-postgres-dockerhub is someone who knows how to make it working with local-path StorageClasses ? best regards

Hi, I just tried to install postgres over helm chart where you can directly define used StorageClass without any further configuration and it seems to work (created pv and pvc are Bound)

Copy code

$ helm repo add bitnami <https://charts.bitnami.com/bitnami>
$ helm install postgres bitnami/postgresql --set global.storageClass=local-path
$ kubectl get sc,pv,pvc
NAME                                               PROVISIONER             RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE

the final objective is to build a postgres image from source on an UBI-minimal base image... there is stil some work to do :)
