6 kubectl port-forward - Forward one or more local ports to a pod
7
11 kubectl port-forward [OPTIONS]
12
16 Forward one or more local ports to a pod. This command requires the
17 node to have 'socat' installed.
18 Use resource type/name such as deployment/mydeployment to select a pod.
21 Resource type defaults to 'pod' if omitted.
22 If there are multiple pods matching the criteria, a pod will be
25 selected automatically. The forwarding session ends when the selected
26 pod terminates, and rerun of the command is needed to resume forward‐
27 ing.
