-# Pod Security Policy (PSP)
-
-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.
-If you have PSP enabled on the cluster, and you deploy ingress-nginx,
-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`.
