wsl minikube的简单应用

minikube

• minikube官网：https://minikube.sigs.k8s.io/docs/
• minikube是容器编排与管理的工具，本机事先已经安装了docker
• 进入minikube官网，点Get Started！长这熊样
  看一硬件要求
  • CPU 核心数 >= 2
  • 内存 2GB
  • 磁盘 20GB
  • 网络连接
  • 容器或虚拟机管理器，如：docker…
  • 此时下滑，看一下安装步骤

开始安装

1. 选择合适自己的安装包，我这里选Linux、ARM64、Stable、Binary
   然后捏，复制下边的curl指令，粘贴进命令行，安装即可

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-arm64
sudo install minikube-linux-arm64 /usr/local/bin/minikube
% Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 86.6M  100 86.6M    0     0    14.7M         0  0:00:05  0:00:05 --:--:-- 18.9M

2. minikube start

minikube start
  minikube v1.32.0 on Ubuntu 22.04 (arm64)
✨  Automatically selected the docker driver. Other choices: none, ssh
  The "docker" driver should not be used with root privileges. If you wish to continue as root, use --force.
  If you are running minikube within a VM, consider using --driver=none:
    https://minikube.sigs.k8s.io/docs/reference/drivers/none/

❌  Exiting due to DRV_AS_ROOT: The "docker" driver should not be used with root privileges.

出错了，它说不让在root权限下运行
此时exit出root用户，再次执行

minikube start
  minikube v1.32.0 on Ubuntu 22.04 (arm64)
  Unable to pick a default driver. Here is what was considered, in preference order:
     ▪ docker: Not healthy: "docker version --format {{.Server.Os}}-{{.Server.Version}}:{{.Server.Platform.Name}}" exit status 1: permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/version": dial unix /var/run/docker.sock: connect: permission denied
     ▪ docker: Suggestion: Add your user to the 'docker' group: 'sudo usermod -aG docker $USER && newgrp docker' <https://docs.docker.com/engine/install/linux-postinstall/>
  Alternatively you could install one of these drivers:
     ▪ kvm2: Not installed: exec: "virsh": executable file not found in $PATH
     ▪ qemu2: Not installed: exec: "qemu-system-aarch64": executable file not found in $PATH
     ▪ podman: Not installed: exec: "podman": executable file not found in $PATH
     ▪ virtualbox: Not installed: unable to find VBoxManage in $PATH

❌  Exiting due to DRV_NOT_HEALTHY: Found driver(s) but none were healthy. See above for suggestions how to fix installed drivers.

又出错了，它给出了docker安装的建议：
Add your user to the 'docker' group: 'sudo usermod -aG docker $USER && newgrp docker

执行它：sudo usermod -aG docker $USER && newgrp docker

然后再执行它：minikube start 此时发现minikube启动成功了

3. 执行 kubectl get po -A，发现如下错误

Command 'kubectl' not found, but can be installed with:
sudo snap install kubectl

那就先安kubectl：https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/

执行： curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/arm64/kubectl"，拉取二进制文件

执行：kubectl version，查看是否安装成功

Client Version: v1.29.0
Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3
Server Version: v1.28.3

执行：minikube dashboard
打开在浏览器中打开控制面板查看minikube信息

此时看一下windows内存剩余，wsl占用还是可以接受的

使用：minikube stop 关闭minikube
