The `kubectl cordon` command is used to mark a node as unschedulable. This command is aimed at nodes and will not allow anything to be scheduled on a node that has been cordoned. After cordoning the status will be "Ready,SchedulingDisabled"

The `kubectl uncordon` will allow pods to be rescheduled back on node after it was cordoned

The `kubectl drain` command, drains a node of its resources

The `kubectl cluster-info` to get information on the cluster and debug information

The `kubectl taint` command, taints a node so that you can control what resources attach to it, primarily by using tolerations

The `kubectl logs` command is used to print the logs from a container in a pod.

The `kubectl attach` command is a convenient way to attach to a running container. It allows you to attach to the standard input, tty, and error streams of a running container.

The kubectl exec command is used to run commands on a container within a pod.

The `kubectl auth` can-i command is used to determine if a user can perform a certain action.

The `kubectl auth reconcile` command is used to reconcile rules for RBAC role, role binding, cluster role, and cluster role binding objects. This is prefered over merge because of the extra rules on merging that are provided.

The kubectl auth whoami command is used to get the current user and the groups that the user is part of.
