安裝kubectl 這個是kubernetes的客戶端 可以使用類似docker run容器語法管理操作
cat <<EOF > /etc/yum.repos.d/kubernetes.repo [kubernetes] name=Kubernetes baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64 enabled=1 gpgcheck=1 repo_gpgcheck=1 gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg EOF yum install -y kubectl
安裝minikube
curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube && sudo cp minikube /usr/local/bin/ && rm minikube
啟動minikube
minikube start
如果報錯 如以下訊息
因為minikube預設需要虛擬機來初始化kubernetes環境，但Linux例外 可以使用--vm-driver=none 參數來使用自已的環境
# linux 下獨有，不依賴虛扯機啟動 sudo minikube start --vm-driver=none # 如果是Mac or Windows，安裝VirtualBox後再重新start即可 sudo minikube start
啟動成功訊息如下
