sysctl Error With Network-Mode: Host

[infinitydon]

Hi,

Currently trying to bring an SRL in host network mode using the following manifest:

name: srl-lab

topology:
  kinds:
    srl:
      type: ixrd3
      image: ghcr.io/nokia/srlinux:23.10.1-218
  nodes:
    edge-01:
      kind: srl
      network-mode: host
  links:

But I am getting the following error when I try to deploy:

ubuntu@srlinux-23:~/containerlab$ sudo containerlab deploy

I followed the example config here https://containerlab.dev/manual/nodes/#host-mode

Any idea what could be wrong?

Thanks

SR Linux container does not support host network mode
