Setting up and using port forwarding

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

You start port forwarding with the port-forward command:

epinio app port-forward samplejava 34506:8080

This forwards the traffic coming from localhost:34506 to the remote :8080. Specification of the local port is optional. When none is provided a random port is selected.

Point to a specific instance

You can direct port forwarding to a specific instance of your application.

To do this:

  • list all the instances of the application
  • pick the desired ID
  • use the --instance flag to direct the port forwarding to that instance
-> % epinio app show samplejava
