Multus with Contiv

[networkop]

Hi, I was wondering, since you've mentioned Contiv as one of the CNI plugins you support, has anyone done any real work integrating the two? I'm struggling to understand how to pass network names to contiv through CNI configuration in NetworkAttachmentDefinition, since by default they try to read them from pod labels.

@networkop Could you please explain the details. FYI https://github.com/contiv/vpp/tree/master/cmd/contiv-cni

Hi @rkamudhan , sure.
I'm trying to get contiv working with multus. Specifically, I want to attach a pod to a specific network inside contiv. So normally, without multus, I do that by specifying labels inside pod's metadata, e.g. if i want to attach my pod to contiv-net:

apiVersion: v1
kind: Pod
metadata:
  labels:
    io.contiv.network: contiv-net

What I want is to use multus to attach a pod to multiple contiv networks, which would have been possible if I could specify io.contiv.network inside a NetworkAttachmentDefinition.

But now I've had a closer look at the contiv cni plugin and it looks like they're taking those label values by quering api server directly and not from a cni configuration file, so doesn't look like it's possible.

I have the same question: how to integrate Multus with Contiv correctly?
Did @networkop solve it successfully, so closed this issue?
Would you share the way you get it works, thank you!

I'm interested in integrating contiv with multus as well. @networkop didn't solved it as it didn't seem possible at the time. But that was in 2018. Maybe things changed since then.
