Red Hat OpenShift Container Platform

Use port forwarding

You can use the OpenShift CLI (oc) to port-forward one or more local ports to a pod.

Procedure

Use a command similar to the following to listen on the specified port in a pod:
```
$ oc port-forward <pod> [<local_port>:]<remote_port> [...[<local_port_n>:]<remote_port_n>]
```
For example, use the following command to listen on ports 5000 and 6000 locally and forward data to and from ports 5000 and 6000 in the pod:
```
$ oc port-forward <pod> 5000 6000
```
Example output
```
Forwarding from 127.0.0.1:5000 -> 5000
Forwarding from [::1]:5000 -> 5000
Forwarding from 127.0.0.1:6000 -> 6000
Forwarding from [::1]:6000 -> 6000
```
For example, use the following command to listen on port 8888 locally and forward to 5000 in the pod:
```
$ oc port-forward <pod> 8888:5000
```
Example output
```
Forwarding from 127.0.0.1:8888 -> 5000
Forwarding from [::1]:8888 -> 5000
```
For example, use the following command to listen on a free port locally and forward to 5000 in the pod:
```
$ oc port-forward <pod> :5000
```
Example output
```
Forwarding from 127.0.0.1:42390 -> 5000
Forwarding from [::1]:42390 -> 5000
```
Alternatively, use the following command to listen on a free port locally and forward to 5000 in the pod:
```
$ oc port-forward <pod> 0:5000
```
