K8s的可选发行版

k8s/MiniKube（开发环境）

minikube quickly sets up a local Kubernetes cluster on macOS, Linux, and Windows. We proudly focus on helping application developers and new Kubernetes users.

  • 基于 VM/Container 启动的 K8s 集群；
  • 支持多节点集群（在一个物理节点启动两个VM组成K8s），而不是多个物理节点组成K8s集群；

安装

https://minikube.sigs.k8s.io/docs/start/

https://github.com/kubernetes/minikube/releases/latest

Linux

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube && rm minikube-linux-amd64

Windows

安装 Hyper-V

【控制面板】->【程序】->【打开和关闭 windows 功能】-> 勾选 Hyper-V 的选项（包括所有子项）-> 重启电脑

启用 Hyper-V

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All

minikube start --driver=hyperv 
# To make hyperv the default driver:
minikube config set driver hyperv

使用

# minikube 会自动下载 kubectl
alias kubectl="minikube kubectl --"
# 启动 minikube，使用国内的镜像
minikube start --image-repository='registry.cn-hangzhou.aliyuncs.com/google_containers' --base-image=registry.cn-hangzhou.aliyuncs.com/google_containers/kicbase:v0.0.44

本地镜像使用

minikube推送镜像到本机

使用 docker driver，因为 docker daemon 存在，可以共享 docker sock；

podman driver 需要配合 cri-o 而非 docker ，因为 podman 不存在 daemon 进程。

Kind

Kubernetes IN Docker - local clusters for testing Kubernetes.

kind is a tool for running local Kubernetes clusters using Docker container "nodes". kind was primarily designed for testing Kubernetes itself, but may be used for local development or CI.
