CentOS 7安装Minikube v1.17.0
CentOS 7安装minikube
一、简介
Minikube是单机版的Kubernetes集群，能够在我们本地的个人电脑（包含Windows、macOS、Linux系统）运行Kubernetes集群，让我们进行日常的开发工作
官方地址：https://kubernetes.io/docs/tasks/tools/install-minikube/
二、安装步骤
1、检查是否开启虚拟化，运行以下命令验证输出是否为非空
grep -E --color 'vmx|svm' /proc/cpuinfo
2、安装docker （可以参考之前博客）
3、安装kubectl
$ cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF
$ yum install kubectl
4、安装minikube
下载地址：https://github.com/kubernetes/minikube/tags
mv minikube /usr/local/bin
chmod +x minikube
5、启动minikube
minikube start --driver=none --memory=8192 --cpus=4 --kubernetes-version=v1.17.0 --image-repository=registry.aliyuncs.com/google_containers
* minikube v1.12.1 on Centos 7.6.1810 (kvm/amd64)
* Kubernetes 1.18.3 is now available. If you would like to upgrade, specify: --kubernetes-version=v1.18.3
* Using the none driver based on existing profile
! The 'none' driver does not respect the --cpus flag
! The 'none' driver does not respect the --memory flag
! The 'none' driver does not respect the --cpus flag
! The 'none' driver does not respect the --memory flag
* Starting control plane node minikube in cluster minikube
* Restarting existing none bare metal machine for "minikube" ...
* OS release is CentOS Linux 7 (Core)
* Preparing Kubernetes v1.17.0 on Docker 19.03.12 ...
* Configuring local host environment ...
*
! The 'none' driver is designed for experts who need to integrate with an existing VM
* Most users should use the newer 'docker' driver instead, which does not require root!
* For more information, see: https://minikube.sigs.k8s.io/docs/reference/drivers/none/
*
! 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, run:
*
- 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 Kubernetes components...
* Enabled addons: default-storageclass, storage-provisioner
* Done! kubectl is now configured to use "minikube"

三、其他操作
1、启动、停止、删除集群
$ minikube start --driver=none --memory=8192 --cpus=4 --kubernetes-version=v1.17.0 --image-repository=registry.aliyuncs.com/google_containers
$ minikube stop
$ minikube delete
2、列出当前支持的插件

3、启用指定插件，比如efk
minikube addons enable efk
4、禁用指定插件，比如efk
minikube addons disable efk
5、运行一个实例应用并暴露服务
kubectl create deployment my-nginx --image=nginx
kubectl expose deployment my-nginx --type=NodePort --port=8080
