## Create Pod that uses the container runtime default seccomp profile
Most container runtimes provide a sane set of default syscalls that are allowed
or not. You can adopt these defaults for your workload by setting the seccomp
type in the security context of a pod or container to `RuntimeDefault`.
{{< note >}}
If you have the `SeccompDefault` [feature gate](/docs/reference/command-line-tools-reference/feature-gates/) enabled, then Pods use the `RuntimeDefault` seccomp profile whenever
no other seccomp profile is specified. Otherwise, the default is `Unconfined`.
{{< /note >}}
Here's a manifest for a Pod that requests the `RuntimeDefault` seccomp profile
for all its containers:
{{< codenew file="pods/security/seccomp/ga/default-pod.yaml" >}}
Create that Pod:
```shell
kubectl apply -f https://k8s.io/examples/pods/security/seccomp/ga/default-pod.yaml
```
```shell
kubectl get pod default-pod
```
The Pod should be showing as having started successfully:
```
NAME READY STATUS RESTARTS AGE
default-pod 1/1 Running 0 20s
```
Finally, now that you saw that work OK, clean up:
```shell
kubectl delete pod default-pod --wait --now
```
