当DevOps遇上Kubernets 01 Linux环境配置

前言 电脑配置

如果是在个人电脑上学习安装，建议CPU 4核以上，内存：16G，磁盘空间40G以上，如果配置不够跑起来需要较强的等待耐心！

一 Linux 更换软件安装源

配置国内软件安装源

由于国外的Linux软件包源速度比较慢，建议切换成国内的安装源，可以大大提高软件安装的速度。

Ubuntu 18.04 配置

mv /etc/apt/sources.list  /etc/apt/source.backup
cat >>/etc/apt/sources.list<<EOF
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
EOF

apt update

CentOS7 配置

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

yum makecache

yum update

二 Docker 安装

Ubuntu 18.04 安装 Docker

sudo apt-get remove docker \
               docker-engine \
               docker.io

1 安装apt-get系统工具

sudo apt-get update

2 安装允许apt通过HTTPS使用存储库

sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common

3 安装GPG证书

curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

4 写入软件源信息

sudo add-apt-repository "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"

5 更新并安装Docker-CE

sudo apt-get -y update
sudo apt-get -y install docker-ce

CentoOS 7 安装Docker

1. 卸载旧版本

   sudo yum remove docker \
                     docker-client \
                     docker-client-latest \
                     docker-common \
                     docker-latest \
                     docker-latest-logrotate \
                     docker-logrotate \
                     docker-engine
   

2. 安装依赖包

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

3. Docker 安装源

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

   4.安装Docker

   安装最新版

   yum install -y docker-ce docker-ce-cli containerd.io
   

   安装指定版

   yum install -y docker-ce-18.09.0 docker-ce-cli-18.09.0 containerd.io
   

   启动 docker

    #开机启动
   systemctl  enable  docker
   systemctl start docker
   

三 配置Docker国内镜像源

cat >>/etc/docker/daemon.json<<EOF
{
 "registry-mirrors": ["https://yecrg48y.mirror.aliyuncs.com","https://registry.docker-cn.com","http://hub-mirror.c.163.com","https://docker.mirrors.ustc.edu.cn/"],"insecure-registries": ["agileone.local:8081","docker.agileone.local:8081"]
}
EOF

sudo systemctl daemon-reload

检查Docker是否安装好

 sudo docker version
