I'm trying to install in my Kubernetes cluster TimescaleDB, unfortunately following more tutorials I always fall in a similar error.

For example, I tried this tutorial but the pod 'timescale-db-timescaledb-data-1' has the error:

install: cannot change owner and permissions of ‘/var/lib/postgresql/pgdata’: No such file or directory
install: cannot create directory ‘/var/lib/postgresql/pgdata’: Permission denied

I also tried to install it from the Lens Charts repository, but nothing works.

PS: I need to have 3 nodes in my cluster (minikube on Linux)
