cilium VS multus-cni

They would have had to add a few externals to get to Graduated but it's definitely a minority:

Next-gen networking thanks to Cilium

Hello there, I recently have the need to proxy my pod traffic through WireGuard. I initially have my eyes on https://github.com/angelnu/pod-gateway but I just couldn't get it working. It turns out that Cilium made a CVE patch couple years ago that basically nuked ability to do inter-pod encapsulated traffic (https://github.com/cilium/cilium/issues/15991). I wonder if there is any other way that can let me do this without switching out of Cilium? Thank you guys in advance :)

I have used Cilium as CNI and installing it with helm.

I'm using the default RaspiOS Lite 64bits and as highlighted in this issue, the RaspiOS kernel does not support CONFIG_ARM64_VA_BITS_48, which makes cilium-envoy to fail building. As solution, I was told to use either Ubuntu as base OS or Traefik Ingress Controller, which is not configured in K3s.

Working on integrating cilium and loxilb as a hobby k8s project. Both are eBPF based and will be interesting to see what will be the final outcome.

Particularly in Cilium, Gateway API is very proof-of-concept. So much so that you can't even change the type of the underlying service (or anything else about the generated object) yet.

Authentication using mTLS was later merged into cilium (https://github.com/cilium/cilium/pull/24263). It uses mTLS between cilium agents to authorize flows, but do note that the mTLS auth is de-coupled from the datapath transport (i.e. you need to configure cilium to use ipsec or wireguard, as otherwise traffic won't be encrypted). As a consequence, there are some gaps in the implementation right now, like packet drops. see https://github.com/cilium/cilium/issues/23808

network plugin to be used, based on the documentation. (Project Calico ,Flannel, Cilium )

I have to plan the migration of our software we are running on a single node with docker-compose to K8, and i'm kinda lost in the plugins and the basic settings. One of our MS has to use static MAC address in order to run fine, bcs it's using a certificate. Is it possible to run a pod with static MAC address, or do you suggest to use multus-cni or something like this?

I opened a PR to add support for CNI v1.0.0 to Multus (https://github.com/k8snetworkplumbingwg/multus-cni/pull/879) but it was closed in July because 4.0 was "pretty near". Of course now it's almost February and we haven't seen so much as an Alpha of 4.0 since October. Sure wish they'd get their act together.

Multus

One thing I will note is that in the end only one process can listen at a certain endpoint (let's say 80 or 443) at the end of the day without some other complexity, AFAIK there isn't an Multus-like project for Ingress Controllers... A 2 tier setup would work but that just feels like overkill (especially for me).
