 ## Choosing container runtime
 Prior to 5.3 release, the user has to specify the correct container runtime type and its socket path. In 5.3.0 release, the enforcer is able to automatically detect the container runtime at its default socket location. The settings of docker/containerd/crio/k8s/bottlerocket become deprecated. If the container runtime socket is not at the default location, please specify it using 'runtimePath' field. In the meantime, the controller does not require the runtime socket to be mounted any more.
