+```bash
+kubectl apply -f .\kube\02-databases\01-postgres\01-secret.yaml
+```

+
+#### Config Map
+
+```bash
+kubectl apply -f .\kube\02-databases\01-postgres\02-configmap.yaml
+```
+
+Set values:

+
+#### Stateful Set
+
+This is the specifications for postgres.
+
+```bash
+kubectl apply -f .\kube\02-databases\01-postgres\03-statefulset.yaml
+```
+
+Set storage size for permanent storage
+
+#### Service
+
+this exposes port and ip.
+
+```bash
+kubectl apply -f .\kube\02-databases\01-postgres\04-service.yaml
+```
