首先要安装docker这个环境是需要自己安装的。相关步骤如下：

1

3
4
5

9
10
11
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
安装docker
yum list docker-ce --showduplicates | sort -r 查看docker相关版本
#yum install docker-ce #由于repo中默认只开启stable仓库，故这里安装的是最新稳定版。
#yum install <FQPN> # 例如：yum install docker-ce-18.06.0.ce -y
#以下是验证过的版本，建议安装
yum install docker-ce-18.06.0.ce -y
systemctl start docker
systemctl enable docker
docker version（因为安装的是1.13.4版本的k8s,建议安装docker18.06）

然后使用阿里云修改好的minikube进行安装，否则在初始化minikube的时候会卡在墙上下不来

1
2
3
curl -Lo minikube http://kubernetes.oss-cn-hangzhou.aliyuncs.com/minikube/releases/v0.35.0/minikube-linux-amd64
chmod +x minikube
mv minikube /usr/bin/minikube
注意一点要关掉swap：关闭命令swapoff -a

加载阿里云k8s的官方源并且安装相关命令组件

1

cd /etc/yum.repos.d/
cat>>kubernetes.repo<<EOF

yum install kubectl kubelet kubeadm -y
systemctl start kubelet && systemctl enable kubelet

使用缺省VirtualBox驱动来创建Kubernetes本地环境

minikube start --registry-mirror=https://registry.docker-cn.com

出现如下字样

- Verifying component health .....
+ kubectl is now configured to use "minikube"
= Done! Thank you for using minikube!

则本地的minikube安装完成。当然这个不能访问外网，单独装ingress或者端口转发即可

  type: NodePort
status:
  loadBalancer:
    ingress:
    - ip: 39.108.26.119（此处更改成自己本机ip）

以上yaml创建pod的命令是：

kubectl apply -f xxxx.yaml

业务镜像可以拉取gitlab的，这里没做cofigmap，需要自己配。生成业务编排需自己编写yaml

以下是简单安装脚本。

#!/bin/bash

#安装docker相关，用以拉取本地所需镜像,版本采用docker-ce .06版，支持1.13版kubernetes

#检测网卡是否是固定ip

grep -rE "dhcp" /etc/sysconfig/network-scripts/ifcfg-*

if [ $? -eq  ];

then

    echo "网卡为DHCP模式请更改为规定ip"

    exit

else

    echo "网卡正常。"

fi

yum clean all && yum repolist

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

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

yum install docker-ce-18.06..ce -y

systemctl start docker

systemctl enable docker

VERSION=`docker version`

if [ $? -eq  ];

then

    echo "输出docker版本信息：$VERSION"

else

    echo "docker安装出错，请检查错误日志"

    exit

fi

echo "" >/proc/sys/net/bridge/bridge-nf-call-iptables #此步是保证iptables正确转发获取镜像，否则会报dns解析错误
