They also have some interesting HA patterns because every node is in the control plane, which is cool but really only useful for particular use cases. Whatever you choose, the most important thing is getting started. Want to update to a newer k3s release? Gitops change. While you can use a full blown etcd cluster Dqlite is much smaller which fits better into small edge-machines. K3s' design has nothing help with edge or RPi scenarios as its advertisement and there's no any outstanding effort regarding to resource footprint optimization. どういう機能があるかについてもリストアップしてみます。 ※注：このリストは最初に述べたとおり、そもそもk3sとMicroK8sの用途が違うものをリストアップしているので なのが良くないということではなく、それぞれに向き不向きがあり、どの分野に適しているかということを示して The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives. maintain and role new versions, also helm and k8s Self-Hosting Guide. sudo microk8s enable dns sudo microk8s enable dashboard Use microk8s status to see a list of enabled and available addons.

An intro to MicroK8s; K8s at the edge: easy as “Pi” Embedded Kubernetes for secure IoT Edge; MicroK8s on IBM Z — minimal footprint meets zero downtime; Self-healing Kubernetes at the edge: MicroK8s, Raspberry Pis and Portainer; Simplifying Kubernetes across the Clouds: MicroK8s on NVIDIA Tech Stack MicroShift is a project that optimizes OpenShift Kubernetes for small form factor and edge computing. I picked the Raspberry Pi 4 with 4GB of RAM since it would give a good memory to CPU ratio: 1x1. Edit: some were asking hardware specs: I’m running 3 raspberry Pi 4-8gb and 3 raspberry Pi 3b as worker nodes. Unlike k3s, it also brings cloud-specific components along. rook. These Pi's are really not powerful enough to run the Control Plane components, so I've ended up setting them up as worker nodes and running a single master node on a VM on my Mac. Lightweight Kubernetes on Raspberry Pi. Would probably still use minikube for single node work though. Just the kernel, not userspace. I contacted Canonical to ask their advice about the above, and was told that by default, MicroK8s installs the Calico network driver and uses dqlite rather then etcd, which is not needed for single-node deployments. It is an optimized Kubernetes distribution that can run on ARM architecture, x86, and IoT devices to name a few. 04LTS on amd64. Raspberry pi’s are pretty easy and cheap to setup.
