How to try

How to experiment with k8s locally

Minikube

• Why

  • running on all OS

  • beginner friendly tool

• What

  • Kubernetes SIGs project

  • approach of spawning a VM that is essentially a single node K8s cluster

  • minikube’s addon system that helps you integrating things like, Helm, Nvidia GPUs and an image registry with your cluster.

• How

  • minikube start

  • minikube dashboard

    • opens a dashboard in the browser to deploy apps through UI

kind

• Why

  • significantly faster startup speed compared to spawning VM

• What

  • Kubernetes SIGs project

  • it moves the cluster into Docker containers

  • ability to load my local images directly into the cluster

k3s

• What

  • minified version of Kubernetes developed by Rancher Labs
  • a single binary with a size of around 60 MB

    • by removing dispensable features (legacy, alpha, non-default, in-tree plugins) and using lightweight components (e.g. sqlite3 instead of etcd3)
