    Kubernetes supports over 30 Admission Controllers. Subsequent to Authorization and Authentication, Admission Controllers are the final step in a 3-step process before Kubernetes persists the resource in etcd (a consistent and highly-available key value store used as Kubernetes’ backing store for all cluster data). Some relevant Admission Controllers to secure running containers are: PodSecurityPolicy: this option […]
