How to use Port Forwarding

This how-to demonstrates how to use port forwarding to access a running application.

Port forwarding can be started with the port-forward command:

epinio app port-forward samplejava 34506:8080

This will forward the traffic coming from localhost:34506 to the remote :8080. Note that specification of the local port is optional. When none is provided a random port will be selected.

Point to a specific instance

Port forwarding can be directed to a specific instance of your app. To do this list all the instances of the application, pick the desired ID, and then use the --instance flag to direct the port forwarding to that instance:

-> % epinio app show samplejava
