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

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.
