Fly Kubernetes
Seems like Fly.io Machines are trying reimplement Kata Containers with the Firecracker backend [0].
Kata has a guest image and guest agent to run multiple isolated containers [1].

Kata Containers: Virtual Machines (VMs) that feel and perform like containers
> Last time I looked (a few months ago), the documentation was pretty sparse or outdated.
It still is, though it works somewhat seamlessly when installing with https://github.com/kata-containers/kata-containers/blob/main...
Though only one of the hypervisors works well.

Container security best practices: Ultimate guide
My home k8s cluster is now "locked down" using micro-vms (kata-containers[0]), pod level firewalling (cilium[1]), permission-limited container users, and mostly immutable environments. Given how quickly I rolled this out; the tools to enhance cluster environment security seem more accessible now than my previous research a few years ago.
I know it's not exactly a production setup, but I really do feel that it's the most secure runtime environment I've ever had accessible at home. Probably more so than my desktops, which you could argue undermines most of my effort, but I like to think I'm pretty careful.
In the beginning I was very skeptical, but being able to just build a docker/OCI image and then manage its relationships with other services with "one pane of glass" that I can commit to git is so much simpler to me than my previous workflows. My previous setup involved messing with a bunch of tools like packer, cloud-init, terraform, ansible, libvirt, whatever firewall frontend was on the OS, and occasionally sshing in for anything not covered.

Docker Without Docker
I'm really impressed by fly.io, and the candidness with which they share some of their really awesome technology. Being container-first is the next step for PaaS IMO and they are ahead of the pack.
I aim to build a platform like theirs someday (probably not any time soon) but I don't think I'd do any of what they're doing -- it feels unnecessary. Bear with me as I recently learned that they use nomad[0] and some of these suggestions are kubernetes projects but I'd love to hear why the following technologies were decided against (if they were):
- kata-containers[1] (it does the whole container -> VM flow for you, automatically, nemu, firecracker) with multiple VMM options[2]
- linuxkit[3] (let's say you didn't go with kata-containers, this is another container->VM path)
- firecracker-containerd[4] (very minimal keep-your-container-but-run-it-as-a-VM)
- kubevirt[5] (if you just want to actually run VMs, regardless of how you built them)
- Ceph[6] for storage -- make LVM pools and just give them to Ceph, you'll get blocks, distributed filesystems (CephFS), and object gateways (S3/Swift) out of it (in the k8s space Rook manages this)
As an aside to all this, there's also LXD, which supports running "system" (user namespace isolated) containers, VMs (somewhat recent[7][8]), live migration via criu[9], management/migration of underlying filesystems, runs on LVM or zfs[10], it's basically all-in-one, but does fall behind in terms of ecosystem since everyone else is aboard the "cloud native"/"works-with-kubernetes" train.
I've basically how I plan to run a service like fly.io if I ever did -- so maybe my secret is out, but I sure would like to know just how much of this fly.io got built on (if any of it), and/or what was turned down.

Route Pod-Traffic Through WireGuard w/ 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 :)

Need advice on K3s cluster setup
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.
- MetalLB or Cilium?

Ask r/kubernetes: What are you working on this week?
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.

Saying Goodbye to Ingress: Embracing the Future of Kubernetes Traffic Management with Gateway API and Cilium
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.

Isn't Istio Ambient mesh a fantastic step to simplify operating istio? Here's a video explaining the architecture!
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
