Setting up a highly available Kubernetes cluster with

For anyone that wants to experiment with a highly available kubernetes cluster without shelling out a significant amount of money to a cloud provider, there's no better way to get started than K3s. This small kubernetes distro is meant for resource-constrained devices, making it the perfect fit for a Pi. I was able to successfully run a K3s cluster on 3 x Raspberry Pi 4s with 4GB of RAM each We will use mysql to setup HA. On each master node, execute below command to setup k3s cluster. curl -sfL https://get.k3s.io | sh -s - server --datastore-endpoint=mysql://username:password@tcp ( Once the installation is completed, execute below command to see the status of the k3s service Multi-master / HA k3s for my Raspberry Pi cluster. k3sup join --user pi --ip --server-ip \. k3sup join --user pi --ip --server-ip \. arkade install openfaas-ingress --ingress-class traefik --email alex@kubecon.k3sup.dev --domain kubecon.k3sup.dev. faas-cli store deploy --platform armhf.

Why would you use K3s on a Raspberry Pi and not plain Kubernetes? The short answer is that Kubernetes was not developed with your small Raspberry Pi processor and memory in mind. The longer answer is that K3s has everything you need for your Raspberry Pi from Kubernetes. It was developed for small servers without all of the unnecessary extras that Kubernetes has. This allows the memory footprint to be smaller on your Raspberry Pi and uses less than 40mb of space on your SD card so. Installing MariaDB HA Cluster on K3S Cluster installed on Raspberry Pi (arm64 arch That's all, so with the above command you can have a two-node cluster up and running, whether that's using VMs on-premises, using Raspberry Pis, 64-bit ARM or even cloud VMs on EC2. Create a multi-master (HA) setup. As of k3s 1.0, a HA multi-master configuration is available through sqlite. A quorum of masters will be required, which means having at least three nodes This topology requires twice the number of hosts as the stacked HA topology. A minimum of three hosts for control plane nodes and three hosts for etcd nodes are required for an HA cluster with this topology. For more information on bootstrapping a cluster, refer to the official Kubernetes documentation. K3s in a Highly Available Mod Result: You can now use kubectl to manage your K3s cluster. If you have more than one kubeconfig file, you can specify which one you want to use by passing in the path to the file when using kubectl:. kubectl --kubeconfig ~/.kube/config/k3s.yaml get pods --all-namespace

  1. You just specify the country code and then SSID and password of your Wi-Fi network. That is all. Now we can start preparing the SD cards for the k3s Kubernetes cluster by calling the script with our parameters like this. ./installRaspbian.sh k3s-master- /mnt/raspbian 'ssh-rsa REDACTED' Europe/Berlin
  2. utes to complete. I'm excited by how easy this is compared to several years ago. Within a short period of time this should also be workable for your Raspberry Pi cluster too. If k3s is new to you, I'd recommend watching Darren Shepherd's KubeCon session
  3. You will need at least one Raspberry Pi 4 with 2GB RAM or more. I would recommend that you buy three if you wish to run a HA cluster, that can tolerate a node failure. Managing costs. Let me put this in bold: you do not need to spend a fortune to build a cluster. 4x RPi 4 including taxes in the UK runs to about 33 GBP per unit ~ about 130 GBP total. If you just want the experience of self-hosting, and to learn about Kubernetes without having to spend too much, you could buy a.
  4. The Raspbernetes project started with a goal to automate the setup and management of a Kubernetes cluster on Raspberry Pis. It aims to be completely declarative and idempotent.

The k3os project was recently announced and I finally got a chance to test it out. k3os greatly simplifies the steps needed to create a Kubernetes cluster along with its counterpart, k3s, to reduce the overhead of running Kubernetes clusters. Paired with Rancher for the UI, all of these components make for an even better option. You can even run Rancher in your (arm64) k3os cluster via th Most importantly for our Raspberry Pi cluster is that K3S works great on ARM processors! One of the differences in k3s is that Rancher replaced the etcd Kubernetes database with SQLite, allowing packaging of k3s as a single binary. It also allows you to run in HA (high availability) mode with a single master node using an external SQLite database cluster. K8s can't do that. You can also. Build your very own self-hosting platform with Raspberry Pi and Kubernetes. (1/8) Build your very own self-hosting platform with Raspberry Pi and Kubernetes - Introduction.

The cluster will serve real workloads — we will deal with exposing it to the internet, IP assignments in home network, reasonable security, distributed storage and monitoring. It is aimed at a home.

Multi-master HA Kubernetes in < 5 minute

Note: Each node on a MicroK8s cluster requires its own environment to work in, whether that is a separate VM or container on a single machine or a different machine on the same network. Note that, as with almost all networked services, it is also important that these instances have the correct time (e.g. updated from an ntp server) for inter-node communication to work Load Balancing a Kubernetes Cluster (Control-Plane) Note: The most common deployment currently for HA Kubernetes clusters w/kube-vip involved kubeadm, however recently we've worked to bring a method of bringing kube-vip to other types of Kubernetes cluster. Typically this deployment method makes use of a daemonset that is usually brought up during the cluster instantiation. This looked really promising, given that setting up, maintaining and grasping the inner workings of a cluster created by kubeadm would probably take us countless of hours or even days. K3s is packaged as a single, static binary with no more than 40MB in size which can even be run on SoCs like the Raspberry Pi Furthermore, K3S installation and cluster deployment are very easy. And you can create clusters with multi masters.
