Container With A hostPath Mount Created

Title: Container With A hostPath Mount Created
Status: test
Description:Detects creation of a container with a hostPath mount. A hostPath volume mounts a directory or a file from the node to the container. Attackers who have permissions to create a new pod in the cluster may create one with a writable hostPath volume and chroot to escape to the underlying node.
