CNI integration

[richardcase]

Integrate CNI into flintlock so that the network interfaces on the host are created/configured via CNI. We need to expose this via the API and also provide a default config.

Yeah there are a few plugins. With #13 we need to look at what plugins there are for macvtap and come up with a recommendation.

When i looked back in April there was a difference in functionality and activity in the plugins i found.

[richardcase]

This is still needed.

Still valid.

I'm Interested. I'll do some research to understand how networking is done now. Is there any documentation about what is intended with this integration?

@pablochacin - we currently use netlink directly to create the interfaces (tap or macvtap). We also support attaching to a bridge.

The Firecracker Go SDK support using CNI. However, thats good for Firecracker but won't cover Cloud Hypervisor. So we probably need to integrate with CNI directly in Flintlock.

Hi @richardcase Thanks for the update.

@richardcase I'm revisiting this issue.

I noticed #856

Does it affect the scope of this issue? My guess is that not, but wanted to check your thought about this.

[richardcase]

I don't think it affects the scope of the issue. We are going to remove macvtap from the firecracker side as we can't keep using our own fork of Firecracker.

Let me know if i can help with anything.

[pablochacin]

@richardcase can please assign it to me?

Thanks @yitsushi , all yours @pablochacin
