mgmt network not working with macvlan

[benbgg]

Hi
I have this macvlan network defined:
[
{
"Name": "newnet",
"Id": "bd967f83ad36ebfc5a6d28bc507975c43e921cff25c004caf31f445f355e56d2",
"Created": "2024-06-08T10:44:32.170746307+01:00",
"Scope": "local",
"Driver": "macvlan",
"EnableIPv6": false,
"IPAM": {
"Driver": "default",
"Options": {},
"Config": [
{
"Subnet": "192.168.37.0/24",
"Gateway": "192.168.37.1"
}
]
},
"Internal": false,
"Attachable": false,
"Ingress": false,
"ConfigFrom": {
"Network": ""
},
"ConfigOnly": false,
"Containers": {},
"Options": {
"parent": "enp6s18"
},
"Labels": {}
}
]
And this is my lab definition:
name: crpdlab01
mgmt:
network: newnet
topology:
nodes:
crpd01:
kind: juniper_crpd
image: crpd-custom:latest
crpd02:
kind: juniper_crpd
image: crpd-custom:latest
crpd03:
kind: juniper_crpd
image: crpd-custom:latest
links:
- endpoints: ["crpd01:eth2", "crpd02:eth1"]
- endpoints: ["crpd02:eth2", "crpd03:eth1"]
- endpoints: ["crpd03:eth2", "crpd01:eth1"]
but "sudo -E deploy" gives:
INFO[0000] Containerlab v0.54.2 started
INFO[0000] Parsing & checking topology file: crpdlan01.clab.yml
WARN[0000] failed gleaning v4 and/or v6 addresses from bridge via netlink, falling back to docker network inspect data
Error: failed to lookup link "br-bd967f83ad36": Link not found
Any suggestions?

Thanks in advance

Hi

My first suggestion would be to format your code with triple backticks to make sure you formatting is properly rendered.

But in general, macvlan mgmt networks are not currently supported.

[benbgg]

Oh dear - guess I'll have to work around it.
#1651 gave me the impression it was - kind of.
Apologies for the formatting:
Thanks for the prompt answer

mgmt:
  network: newnet
topology:
  nodes:
    crpd01:
      kind: juniper_crpd
      image: crpd-custom:latest
    crpd02:
      kind: juniper_crpd
      image: crpd-custom:latest
    crpd03:
      kind: juniper_crpd
      image: crpd-custom:latest
  links:
    - endpoints: ["crpd01:eth2", "crpd02:eth1"]
    - endpoints: ["crpd02:eth2", "crpd03:eth1"]
    - endpoints: ["crpd03:eth2", "crpd01:eth1"]

If I remember correctly the macvlan network could still work, we will just emit a bunch of errors. Having said that, that issue is still worth fixing.

Maybe @pdumais can share how they worked around this

[pdumais]

Yes, I had the same issue I don't remember the full details. But basically, these errors don't prevent you from running the lab right?
It would be nice to have official support for macvlans

[benbgg]

No, I just work around it - just would be handy to go straight in from other machines.
