It handles Kubernetes control-plane operations while users deploy workloads. The article explains that Fly's design uses K3s and Virtual Kubelet, transforms containers into Firecracker microVMs, and connects pods through an internal WireGuard mesh. ### Source excerpt Eons ago, we announced we were working on Fly Kubernetes. It drummed up enough excitement to prove we were heading in the right direction. So, we got hard to work to get from barebones "early access" to a beta release. We'll be onboarding customers to the closed beta over the next few weeks. Email us at sales@fly.io and we'll hook you up. Fly Kubernetes is the "blessed path"™ to using Kubernetes backed by Fly.io infrastructure. Or, in simpler terms, it is our managed Kubernetes service. We take care of the complexity of operating the Kubernetes control plane, leaving you with the unfettered joy of deploying your Kubernetes workloads. If you love Fly.io and K8s, this product is for you. What even is a Kubernete? So how did this all come to be--and what even is a Kubernete? You can see more fun details in Introducing Fly Kubernetes. If you wade through all the YAML and CNCF projects, what's left is an API for declaring workloads and how it should be accessed. But that's not what people usually talk / groan about. It's everything else that comes along with adopting Kubernetes: a container runtime (CRI), networking between workloads (CNI) which leads to DNS (CoreDNS). Then you layer on Prometheus for metrics and whatever the logging daemon du jour is at the time. Now you get to debate which Ingress--strike that--Gateway API to deploy and if the next thing is anything to do with a Service Mess, then as they like to say where I live, "bless your heart". Finally, there's capacity planning. You've got to pick and choose where, how and what the Nodes will look like in order to configure and run the workloads. When we began thinking about what a Fly Kubernetes Service could look like, we started from first principles, as we do with most everything here. The best way we can describe it is the scene from Iron Man 2 when Tony Stark discovers a new element. As he's looking at the knowledge left behind by those that came before, he starts to imagine something entirely different and ## Fully Automated K3S etcd High Availability Install DevFeed: [Fully Automated K3S etcd High Availability Install]() Original publisher: [Read original article]() Author: Techno Tim Published: 2022-03-26T15:00:00Z Content type: tutorial Language: en Sources: [Techno Tim]() Topics: [k3s](), [Ansible](), [Kubernetes](), [Availability](), [Deployment]() Tags: [ansible](), [deployment](), [high-availability](), [k3s](), [kubernetes](), [provisioning]() ### AI overview A tutorial for automating the setup of a highly available k3s cluster using etcd, MetalLB, kube-vip, and Ansible.

It focuses on adding kernel settings, including IPVLAN, needed for networking with Docker Swarm, Kubernetes, and k3s, and covers preparing the build environment and downloading the kernel sources. ### Source excerpt Despite the fact that the NVIDIA Jetson Nano DevKit comes with Docker Engine preinstalled and you can run containers just out-of-the-box on this great AI and Robotics enabled board, there are still some important kernel settings missing to run Docker Swarm mode, Kubernetes or k3s correctly. So, let's try to fix this... Analyzing the Linux Kernel In my last blogpost Verify your Linux Kernel for Container Compatibility, I already shared all the details how you can easily verify the Linux kernel for all Container related kernel settings. So, this first part of analyzing the capabilities of the stock Linux kernel 4.9.x provided by NVIDIA is already done and documented. And this was an easy task as well, so everyone who's interested in these details can repeat the task at his/her own device. Let's recap what we did found. Especially there is one important setting which will be used for networking. This feature called "IPVLAN", is required for Docker Swarm mode and it's also used for networking in Kubernetes and k3s. Building your own Linux Kernel Anyway, even when we'd like to include or change only a single kernel setting, we have to customize the kernel configuration and have to compile and build our own Linux kernel. This is typically a common task for a desktop Linux system, but can be pretty ugly and cumbersome if you have to build the kernel for an Embedded Device. When we look back to all the other NVIDIA Jetson boards, like the TK1, TX1 and TX2, this requires a second Linux machine, running Ubuntu 14.04 or 16.04 on an Intel CPU. Then setting up a complete build system for cross-compiling and all these stuff. Honestly, this is a well-known approach for an Embedded Developer, but the good thing now for the Jetson Nano DevKit this is not required any more. Here the good news: you can customize and build your own Linux kernel directly on the Jetson Nano DevKit! You only need an internet connection and some time to perform all steps on your own. BTW, and this is another
