Port Forwarding

Port forwarding lets developers securely access processes on their Coder workspace from a local machine. A common use case is testing web applications in a browser.

There are two ways to forward ports in Coder:

• The coder port-forward command
• SSH

The coder port-forward command is generally more performant.

coder port-forward

Forward the remote TCP port 8080 to local port 8000 like so:

coder port-forward myworkspace --tcp 8000:8080

For more examples, see coder port-forward --help.

SSH

First, configure SSH on your local machine. Then, use ssh to forward like so:

ssh -L 8080:localhost:8000 coder.myworkspace
