Any idea what I am doing wrong?

[asifiqbal]

I see the service type is ClusterIP. Do I need to change it to NodePort? I am using DigitalOcean for my control plane since I have no credit for Linode.

k8s-manifests % kubectl get svc -n drupal mariadb
NAME      TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)    AGE
mariadb   ClusterIP   10.245.122.64   <none>        3306/TCP   23m
