cilium VS aws-load-balancer-controller

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

I thought at the beginning that such certificate would then expire, but I have seen cert-manager is within ALB code https://github.com/kubernetes-sigs/aws-load-balancer-controller/blob/main/config/certmanager/certificate.yaml so that makes me hesitate about it.

Detailed behavior changes can be found in the release notes for version 2.6.0 of the AWS Load Balancer Controller. https://github.com/kubernetes-sigs/aws-load-balancer-controller/releases The key points include:

If you are using Kubernetes, you can enable security groups on your NLB by using AWS Load Balancer controller version 2.6.0 or later. Enabling NLB security groups using the controller enhances the nodes' security, as inbound rules can be simplified by referencing the NLB security groups. It also provides scaling improvements, as the controller keeps a constant number of security group rules per cluster.

I use the AWS Load Balancer Controller: https://github.com/kubernetes-sigs/aws-load-balancer-controller.

You can install the AWS Load Balancer Controller, and then create an "Ingress" when you install your Nginx Ingress controller, possible with some necessary annotations.

aws-load-balancer-controller

Yes. Google's ingress controller talks to the GCP API and spins up an HTTP LB for you. The AWS LB Controller handles provisioning ALB's for you. And ... I guess other clouds exist too but these are the ones I am familiar with.

NLB don't support weighted target groups and for some reason are extremely slow when adding instances o removing them from target groups, which makes deployments a bit meh (old instances and new instances can be receiving traffic at the same time for up to 2 mins)
