In most clusters today, by default, all resources (e.g. `Deployments` and `ReplicatSets`)

have permissions to create pods.
Kubernetes however provides a more fine-grained authorization policy called

[Pod Security Policy (PSP)](https://kubernetes.io/docs/concepts/policy/pod-security-policy/).
PSP allows the cluster owner to define the permission of each object, for example creating a pod.

you will need to provide the `Deployment` with the permissions to create pods.

Before applying any objects, first apply the PSP permissions by running:
```console
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/docs/examples/psp/psp.yaml

Note: PSP permissions must be granted before the creation of the `Deployment` and the `ReplicaSet`.
