Kubernetes added the official `securityContext.seccompProfile` support in Kubernetes 1.19.
Seccomp is still disabled by default.
The legacy `container.seccomp.security.alpha.kubernetes.io/<PODNAME>` annotation has been deprecated and will be unsupported in Kubernetes 1.25.

A test cluster can be created with the following minikube command:
```
minikube start --feature-gates SeccompDefault=true --extra-config kubelet.seccomp-default=true
```
