symm-mh.clab.yml: ifreload isn't triggered on server nodes

[dteslya]

Hi!

I try to deploy symm-mh.clab.yml topology and all hosts do not get their interfaces configured. After some digging, I found out that the entrypoint script waits for 3 more interfaces to come up aside from eth0. But according to the topology each server has only 2 uplinks to the leaf switches. Changing cmd: 3 to cmd: 2 under the server definition in the topology file seems to fix this issue.

Hi, I think @networkop who is the author of this can comment on that I remember something like that was fixed for another lab

hey @dteslya can you check if the hosts have CLAB_ENV_INTFS env variable configured inside their shell? Containerlab will automatically inject this env var and make it equal to the expected number of interfaces and hosts image should pick it up automatically.

I think cmd field may need to be removed completely to make it work? can you try that?

[dteslya]

Yes, removing the cmd field also worked. And the CLAB_INTFS env variable is injected.

$ docker exec clab-citc-server01 bash -c 'echo "$CLAB_INTFS"'

ok, thanks. I'll do a PR to remove cmd shortly.

[dteslya]

Thank you! Btw, symm-mh.clab.yml has the same issue. Removing cmd also helps there.

The pr has been merged #9

[networkop]

thanks. closing the issue.

[networkop]
