MicroK8s

The smallest, fastest Kubernetes

Single-package fully conformant lightweight Kubernetes that works on 42 flavours of Linux. Perfect for:

• Developer workstations
• IoT
• Edge
• CI/CD

Canonical might have assembled the easiest way to provision a single node Kubernetes cluster - Kelsey Hightower

Why MicroK8s?

• Small. Developers want the smallest K8s for laptop and workstation development. MicroK8s provides a standalone K8s compatible with Azure AKS, Amazon EKS, Google GKE when you run it on Ubuntu.

• Simple. Minimize administration and operations with a single-package install that has no moving parts for simplicity and certainty. All dependencies and batteries included.

• Secure. Updates are available for all security issues and can be applied immediately or scheduled to suit your maintenance cycle.

• Current. MicroK8s tracks upstream and releases beta, RC and final bits the same day as upstream K8s. You can track latest K8s or stick to any release version from 1.10 onwards.

• Comprehensive. MicroK8s includes a curated collection of manifests for common K8s capabilities and services:

  • Service Mesh: Istio, Linkerd
  • Serverless: Knative
  • Monitoring: Fluentd, Prometheus, Grafana, Metrics
  • Ingress, DNS, Dashboard, Clustering
  • Automatic updates to the latest Kubernetes version
  • GPGPU bindings for AI/ML

Quickstart

Install MicroK8s with:

snap install microk8s --classic

MicroK8s includes a microk8s kubectl command:

sudo microk8s kubectl get nodes
sudo microk8s kubectl get services

To use MicroK8s with your existing kubectl:

sudo microk8s kubectl config view --raw > $HOME/.kube/config

User access without sudo

The microk8s user group is created during the snap installation. Users in that group are granted access to microk8s commands. To add a user to that group:

sudo usermod -a -G microk8s <username>

Kubernetes add-ons

MicroK8s installs a barebones upstream Kubernetes. Additional services like dns and the Kubernetes dashboard can be enabled using the microk8s enable command.

sudo microk8s enable dns dashboard

Use microk8s status to see a list of enabled and available addons. You can find the addon manifests and/or scripts under ${SNAP}/actions/, with ${SNAP} pointing by default to /snap/microk8s/current.

Documentation

The official docs are maintained in the Kubernetes upstream Discourse.
