MacOS搭建k3s容器化开发环境 ​

k3s作为k8s的轻量化实现，在windows和macos平台上也是必须借助虚拟机来实现的。这里官方推荐使用的是multipass 这是canonical开发的只能用来创建ubuntu镜像的虚拟机的轻量化实现，类似wsl2之于windows。安装非常简单。

安装k3s虚拟机 ​

bash
brew install multipass --cask

创建并启动虚拟机实例 ​

bash
multipass launch --name k3s-server --cpus 2 --mem 4096 --disk 10G

删除已创建的虚拟机实例 ​

bash
multipass delete k3s-server
multipass purge

参考文档 ​

multipass官方文档
