Descriptions

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.

En kubelet v1.13.6 y v1.14.2, los contenedores para pods que no especifican un intento runAsUser explícito de ejecutarse como uid 0 (raíz) en el reinicio del contenedor, o si la imagen se extrajo previamente en el nodo. Si el pod especificado mustRunAsNonRoot: true, el kubelet se negará a iniciar el contenedor como root. Si el pod no especificó mustRunAsNonRoot: true, el kubelet ejecutará el contenedor como uid 0.
