gVisor CNI tutorial is not working as expected

[milantracy]

Description

I followed https://gvisor.dev/docs/tutorials/cni/ set up networking for a gVisor sandbox using CNI

For the last step, the server doesn't return anything, which is unexpected, I might misconfigure something, otherwise, the CNI tutorial is broken.

$ curl http://${POD_IP}:8000/
curl: (52) Empty reply from server
$ sudo /tmp/runsc/runsc list
ID                PID         STATUS      BUNDLE                   CREATED                          OWNER

I am encountering the same issue when using --ignore-cgroups together with --network=host.
