Mac 安裝 Kubernetes 曲折的經歷

Mac 安裝 Kubernetes 曲折的經歷

 

正常情況下，一般是這樣安裝，進入Docker Desktop 配置界面，勾選 "Enable Kubernetes" 然後單擊“Apply & Restart”

但是你會發現 kubernetes 一直處於 starting 狀態，這是因爲谷歌的 https://gcr.io/ 域名無法訪問。

網上很多解決方案是從鏡像下載，操作有點複雜。我的做法是科學上網，但是最近手上沒有資源可用，無法科學上網。

於是卸載了 Docker Desktop，抱着試試的心態安裝了 minikube 

iMac:~ neo$ brew install minikube

然後啓動 minikube 提示需要 virtualbox 我是iMac 2011的系統是 High Sierra，下載安裝virtualbox 發線最新 6.1 提示出錯，卸載了6.1 安裝 5.x 

啓動 minikube 後 virtualbox 可以彈出，但是運行鏡像出錯。

查看 --driver 參數後，發現可以支持 docker 

iMac:~ neo$ minikube start --help | grep driver=''
      --cache-images=true: If true, cache docker images for the current bootstrapper and load them into the machine. Always false with --driver=none.
      --driver='': Driver is one of: virtualbox, parallels, vmwarefusion, hyperkit, vmware, docker, podman (experimental) (defaults to auto-detect)
      --vm-driver='': DEPRECATED, use `driver` instead.

卸載 virtualbox 後，再重新安裝回 Docker Desktop，你懂 minikube 竟然安裝成功了

iMac:~ neo$ minikube start 

查看運行狀態

iMac:~ neo$ minikube status

查看配置 

iMac:~ neo$ kubectl config view

啓動儀表板

在 Docker Desktop 中查看 Kubernetes 

 

上面的電腦是 iMac，下面我們在MacBook Pro 上再試一次，操作系統已經升級到最新的 macOS Big Sur

Docker 是 Stable 穩定版，上面試 Edge 版本。

安裝 minikube

neo@MacBook-Pro-Neo ~ % brew install minikube

調整一下資源，分配內存4G
