Kubeadm #

kubernetes/kubeadm

Kubeadm is a tool built to provide best-practice “fast paths” for creating Kubernetes clusters. It performs the actions necessary to get a minimum viable, secure cluster up and running in a user friendly way. Kubeadm’s scope is limited to the local node filesystem and the Kubernetes API, and it is intended to be a composable building block of higher level tools.

• 用于快速搭建 kubernetes 集群，目前应该是比较方便和推荐的，简单易用
• kubeadm 是 Kubernetes 1.4 开始新增的特性
• kubeadm init 以及 kubeadm join 这两个命令可以快速创建 kubernetes 集群

MicroK8s #

ubuntu/microk8s

MicroK8s is a small, fast, single-package Kubernetes for developers, IoT and edge.

https://microk8s.io

• Pros:
  • Very easy to install, upgrade, remove
  • Completely isolated from other tools in your machine
  • Does not need a VM, all services run locally
• Cons:
  • Only available for Snap supported Linux Distributions
  • Relatively new, possible unstable
  • Minikube can also run directly on Linux (vmdriver=none), so MicroK8s value proposition is diminished

• Local Kubernetes for Linux – MiniKube vs MicroK8s
