/var/lib/postgresql/data exists but is not empty


% kubectl logs db
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.utf8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

Data page checksums are disabled.

initdb: directory "/var/lib/postgresql/data" exists but is not empty
It contains a lost+found directory, perhaps due to it being a mount point.
Using a mount point directly as the data directory is not recommended.
Create a subdirectory under the mount point.

# db-pod.yaml
        - mountPath: /var/lib/postgresql/data
          name: db-data
          subPath: postgres #Add subPath


% kubectl delete pod db
% kubectl get pod
% kubectl create -f db-pod.yaml #Don't use kubectl apply -f db-pod.yaml 

#postgresql (5) #subpath (1) #kubectl (6) #k8s-troubleshooting (2) #k8s (10)
