unikraft instances tunnel

Forward a local port to an unexposed instance through an intermediate TLS tunnel service.

When you need to access an instance on Unikraft Cloud which is not publicly exposed to the internet, you can use the unikraft instance tunnel subcommand to forward from a local port to a port which the instance listens on.

Code
unikraft instances tunnel <target> ... [flags]

Examples

Forward local port 8080 to instance "nginx" port 8080:

Code
unikraft instance tunnel nginx:8080

Forward local port 8333 to instance "nginx" port 8080:

Code
unikraft instance tunnel 8333:nginx:8080

Forward multiple ports from multiple instances:

Code
unikraft instance tunnel 8080:my-instance1:8080/tcp 8443:my-instance2:8080/tcp

Forward local port 8080 to instance "my-instance1" port 8080 on fra metro using TCP:

Code
unikraft instance tunnel 8080:fra/my-instance1:8080/tcp

Use a custom relay port to avoid collisions:

Code
unikraft instance tunnel -p 5500 my-instance:8080
