Docker安装

1）基础软件源

cd /etc/apt/
mv sources.list sources.list.bak
vim sources.list

2）安装依赖软件

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

3）使用官方推荐源

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"


使用阿里云的源{推荐1}
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
add-apt-repository "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"

使用清华的源{推荐2}
curl -fsSL https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
add-apt-repository "deb [arch=amd64] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu $(lsb_release -cs) stable"

4）检查

apt-get update

5）docker软件安装

# 查看支持的docker版本
apt-cache madison docker-ce
# 安装docker
apt-get install docker-ce -y
# 注：可以指定版本安装docker
apt-get install docker-ce=<VERSION> -y

6）启动docker

systemctl start docker
systemctl status docker

7）测试docker

docker version

8）网卡区别：

安装前：只有ens33和lo网卡 安装后：docker启动后，多出来了docker0网卡，网卡地址172.17.0.1

9）docker服务命令格式

systemctl [参数] docker
参数详解：
start   开启服务
stop    关闭
restart 重启
status  状态

删除docker命令：
yum remove docker-ce
rm -rf /var/lib/docker/
rm -rf /etc/docker

基本目录：
/etc/docker/                docker的认证目录
/var/lib/docker/            docker的应用目录

docker加速器

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://74f21445.m.daocloud.io

加速器配置
1）修改daemon.json文件，增加绿色背景字体内容

# cat /etc/docker/daemon.json
{"registry-mirrors": ["http://74f21445.m.daocloud.io"], "insecure-registries": []}

注意：docker cloud加速器的默认内容是少了一条配置，所以我们要编辑文件在后面加上绿色背景的内容，然后再重启docker
2）重启docker

systemctl restart docker
