Docker——Centos8.2安装Docker

前言

centos8.2版本下如何安装docker

步骤

1. 安装yum-utils

[root@docker yum.repos.d]# yum install -y yum-utils

2. 配置国内源

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

3. 安装docker

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

因为centos8中已经安装了containerd.io,所以我们加上--nobest参数,让他自己选择相应的包即可

4. 查看docker版本

[root@docker yum.repos.d]# docker -v
Docker version 19.03.13, build 4484c46d9d

5. 启动docker

systemctl start docker

6. 运行hello world容器
