A direct bridge to remote container services
PortRelay handles host verification, authentication, container discovery, local binding, and SSH forwarding from one native menu bar app.
Native SSH tunnel
Traffic travels through SwiftNIO SSH. PortRelay never launches a shell script or the system SSH client.
Remote container
The app discovers the container IP on the selected Docker network and forwards traffic to its service port.
PortRelay is an SSH tunnel manager designed for administrators of remote containers. It is an independent project and is not affiliated with Docker, Inc.
