Docker安装步骤

官方步骤

1.配置好虚拟机(CentOS7及以上)且接外网

[root@echohye ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)

2.卸载旧版本

(若之前没装过，此步省略)
/表示连接符而已

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

3. 下载安装gcc相关库

yum install -y gcc
yum install -y gcc-c++

4.安装需要的软件包

yum install -y yum-utils

5.设置stable镜像仓库

# 官方的(不推荐，国内网速不友好)
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

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

6.更新yum软件包索引(可选)

yum makecache fast

7.安装Docker Engine

yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

8.启动docker

systemctl start docker

[root@echohye ~]# ps -df | grep docker
root       5768   5203  0 23:20 pts/1    00:00:00 grep --color=auto docker
[root@echohye ~]# ps -ef | grep docker
root       5649      1  1 23:20 ?        00:00:00 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
root       5770   5203  0 23:20 pts/1    00:00:00 grep --color=auto docker

9.测试

[root@echohye ~]# docker version

 docker-init:

  GitCommit:        de40ad0

10.卸载

systemctl stop docker

yum remove docker-ce docker-ce-cli containerd.io docker-compose-plugin

rm -rf /var/lib/docker

sudo rm -rf /var/lib/containerd

11.阿里云镜像加速

注：当然不一定要用阿里云的镜像，也可以用国内其它的镜像

注册阿里云账号——>控制台——>菜单——>容器镜像服务

个人学习，就选了个人实例

创建之后，点击镜像工具——>镜像加速器
