Description
In kubelet v1.13.6 and v1.14.2, containers for pods that do not specify an explicit runAsUser attempt to run as uid 0 (root) on container restart, or if the image was previously pulled to the node. If the pod specified mustRunAsNonRoot: true, the kubelet will refuse to start the container as root. If the pod did not specify mustRunAsNonRoot: true, the kubelet will run the container as uid 0.

What to do
Workaround: Specify runAsUser directives in pods to control the uid a container runs as. Specify mustRunAsNonRoot:true directives in pods to prevent starting as root (note this means the attempt to start the container will fail on affected kubelet versions).
