安装minikube

1、本地下载kubectl

# 1 配置k8s的yum ,将kubernetes.repo添加到/etc/yum.repos.d中 [kubernetes] name=Kubernetes baseurl=http://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64 enabled=1 gpgcheck=1 repo_gpgcheck=1 gpgkey=http://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg http://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg # 2 安装kubectl yum clean all yum makecache yum install -y kubectl

# 2 安装kubectl

12

yum clean all

13

yum makecache

14

yum install -y kubectl

2、本地下载阿里的minikube

curl -Lo minikube http://kubernetes.oss-cn-hangzhou.aliyuncs.com/minikube/releases/v1.2.0/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

 

 

 

 

 

 

 

 

 

 

 

1

curl -Lo minikube http://kubernetes.oss-cn-hangzhou.aliyuncs.com/minikube/releases/v1.2.0/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

2

 

 

3、安装非最新版的docker-ce

yum install -y yum-utils device-mapper-persistent-data lvm2 yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo yum list docker-ce --showduplicates | sort -r yum install docker-ce-17.12.0.ce

 

 

 

 

 

 

 

 

 

 

 

1

yum install -y yum-utils device-mapper-persistent-data lvm2

2

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

3

yum list docker-ce --showduplicates | sort -r

4

yum install docker-ce-17.12.0.ce 

 

 

4、启动minikube

minikube start --vm-driver=none --registry-mirror=https://registry.docker-cn.com

 

 

 

 

 

 

 

 

 

 

 

1

minikube start --vm-driver=none --registry-mirror=https://registry.docker-cn.com

2

 

 

[root@alluer ~]# minikube start --vm-driver=none --registry-mirror=https://registry.docker-cn.com * minikube v1.2.0 on linux (amd64) * using image repository registry.cn-hangzhou.aliyuncs.com/google_containers * Creating none VM (CPUs=2, Memory=2048MB, Disk=20000MB) ... * Configuring environment for Kubernetes v1.15.0 on Docker 17.12.0-ce * Downloading kubeadm v1.15.0 * Downloading kubelet v1.15.0 * Pulling images ... * Launching Kubernetes ... * Configuring local host environment ... ! The ‘none‘ driver provides limited isolation and may reduce system security and reliability. ! For more information, see: - https://github.com/kubernetes/minikube/blob/master/docs/vmdriver-none.md ! kubectl and minikube configuration will be stored in /root ! To use kubectl or minikube commands as your own user, you may ! need to relocate them. For example, to overwrite your own settings: - sudo mv /root/.kube /root/.minikube $HOME - sudo chown -R $USER $HOME/.kube $HOME/.minikube * This can also be done automatically by setting the env var CHANGE_MINIKUBE_NONE_USER=true * Verifying: apiserver proxy etcd scheduler controller dns * Done! kubectl is now configured to use "minikube"

  - sudo mv /root/.kube /root/.minikube $HOME

  - sudo chown -R $USER $HOME/.kube $HOME/.minikube
