使用 minikube 安装迷你版 Kubernetes

Kubernetes minikube 大约 11878 字

说明

本文基于Windows平台和Hyper-V虚拟机。

官方文档

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

choco 方式安装

choco install minikube

exe 方式安装

https://storage.googleapis.com/minikube/releases/latest/minikube-installer.exe

下载安装后

启动 minikube

默认不带参数启动

minikube start --vm-driver="hyperv" --memory=4096 --hyperv-virtual-switch="Default Switch"

添加镜像等参数

minikube start --vm-driver="hyperv" --memory=4096 --hyperv-virtual-switch="Default Switch" --image-mirror-country="cn" --registry-mirror=https://docker.mirrors.ustc.edu.cn --image-repository=registry.cn-hangzhou.aliyuncs.com/google_containers
  • --vm-driver:如果不写会自动检测,可选值virtualboxvmwarefusionhypervvmware
  • --memory:设置虚机内存大小。
  • --hyperv-virtual-switch:设置Hyper-v网卡。
  • --image-mirror-country:需要使用的镜像镜像的国家/地区代码。留空以使用全球代码。对于中国大陆用户,请将其设置为cn
  • --registry-mirrorDocker Registry的镜像源,集群安装后拉取镜像加速用,可以使用其它加速器地址。这里使用中科大镜像。
  • --image-repository:用来拉取Kubernetes集群所需镜像的仓库。

kubectl

Linux下可以使用alias

alias kubectl="minikube kubectl --"

Windows下可以使用doskey起别名,但比较麻烦,可以直接下载exe二进制文件,加入到环境变量中即可使用kubectl
