## Create a namespace

Create a new namespace called `example`:

```shell
kubectl create ns example
```

The output is similar to this:

```
namespace/example created
```

## Enable Pod Security Standards checking for that namespace

1. Enable Pod Security Standards on this namespace using labels supported by
   built-in Pod Security Admission. In this step you will configure a check to
   warn on Pods that don't meet the latest version of the _baseline_ pod
   security standard.

   ```shell
   kubectl label --overwrite ns example \
      pod-security.kubernetes.io/warn=baseline \
      pod-security.kubernetes.io/warn-version=latest
   ```

2. You can configure multiple pod security standard checks on any namespace, using labels.
   The following command will `enforce` the `baseline` Pod Security Standard, but
   `warn` and `audit` for `restricted` Pod Security Standards as per the latest
   version (default value)

   ```shell
   kubectl label --overwrite ns example \
     pod-security.kubernetes.io/enforce=baseline \
     pod-security.kubernetes.io/enforce-version=latest \
     pod-security.kubernetes.io/warn=restricted \
     pod-security.kubernetes.io/warn-version=latest \
     pod-security.kubernetes.io/audit=restricted \
     pod-security.kubernetes.io/audit-version=latest
   ```

## Verify the Pod Security Standard enforcement

1. Create a baseline Pod in the `example` namespace:

   ```shell
   kubectl apply -n example -f https://k8s.io/examples/security/example-baseline-pod.yaml
   ```
   The Pod does start OK; the output includes a warning. For example:

   ```
   Warning: would violate PodSecurity "restricted:latest": allowPrivilegeEscalation != false (container "nginx" must set securityContext.allowPrivilegeEscalation=false), unrestricted capabilities (container "nginx" must set securityContext.capabilities.drop=["ALL"]), runAsNonRoot != true (pod or container "nginx" must set securityContext.runAsNonRoot=true), seccompProfile (pod or container "nginx" must set securityContext.seccompProfile.type to "RuntimeDefault" or "Localhost")
   pod/nginx created
   ```

1. Create a baseline Pod in the `default` namespace:

   ```shell
   kubectl apply -n default -f https://k8s.io/examples/security/example-baseline-pod.yaml
   ```
   Output is similar to this:

   ```
   pod/nginx created
   ```

The Pod Security Standards enforcement and warning settings were applied only
to the `example` namespace. You could create the same Pod in the `default`
namespace with no warnings.

## Clean up

Now delete the cluster which you created above by running the following command:

```shell
kind delete cluster --name psa-ns-level
```

## {{% heading "whatsnext" %}}

- Run a
  [shell script](/examples/security/kind-with-namespace-level-baseline-pod-security.sh)
  to perform all the preceding steps all at once.

  1. Create kind cluster
  2. Create new namespace
  3. Apply `baseline` Pod Security Standard in `enforce` mode while applying
     `restricted` Pod Security Standard also in `warn` and `audit` mode.
  4. Create a new pod with the following pod security standards applied
