服务器搭建Docker环境

服务器搭建docker环境

一. docker的安装

1. 检查内核版本(docker要求系统内核版本高于3.10)

[root@VM-4-8-centos /]# uname -r
3.10.0-1160.11.1.el7.x86_64

2. 下载阿里的镜像源

[root@VM-4-8-centos data]# wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
--2021-06-23 22:28:46--  https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

3. 安装docker-ce

yum install docker-ce -y /* 安装docker-ce(最新版) */
systemctl start docker /* 启动docker */
systemctl enable docker/* 开启自动启动 */

4. 配置docker镜像源

mkdir -p /etc/docker
sudo vi etc/docker/daemon.json

{
    "registry-mirrors": [
        "https://docker.mirrors.ustc.edu.cn",
        "https://registry.docker-cn.com",
        "https://hub-mirror.c.163.com",
        "https://mirror.ccs.tencentyun.com",
        "http://f1361db2.m.daocloud.io"
    ]
}

systemctl daemon-reload /* 重新加载配置文件 */
systemctl restart docker /* 重新启动docker */

5. 查看是否成功

[root@VM-4-8-centos /]# docker info

 Registry Mirrors:
  https://registry.docker-cn.com/
  http://hub-mirror.c.163.com/

 /* Docker就安装好了 */
