How do I find out the IP address of my Crostini container?

Question

I'm running a Node.js server on Crostini, and trying to access it from and Android browser running on the same Chrome OS device via localhost:8080 doesn't work.

I've tried penguin.linux.test:8080, but that didn't work either. Looks like the Android container didn't get the right DNS settings.

So how do I get the IP address of the Linux container? ifconfig is not installed and apt install fails to get it.

Answer 1

Even easier is just to use hostname -I. This will output the ip address and nothing else

Answer 2

ifconfig is deprecated. Use instead:

ip addr show
