不知道什么原因我浏览器打开乱码，MD文档上传个附件：

CentOS8-Docker.md

因为CentOS8 美国时间9月24日凌晨发布，国内镜像同步时间在9月25日凌晨前后，很多开发中需要的环境还没有现成的包，需要手动安装，此安装方式在 CentOS8 最小安装环境下测试通过。

Docker 卸载老版本（如果安装出错可以执行，否则忽略）

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

安装依赖包

$ sudo yum install -y yum-utils \
  device-mapper-persistent-data \
  container-selinux \
  libcgroup \
  lvm2

## 手动安装RPM，使用阿里云镜像仓库

rpm -ivh https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm
rpm -ivh https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/stable/Packages/docker-ce-19.03.2-3.el7.x86_64.rpm
rpm -ivh

Docker

安装成功，下面安装docker-compose

curl -L https://github.com/docker/compose/releases/download/1.25.0-rc2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

测试是否安装成功

[root@~]# docker-compose -v
docker-compose version 1.25.0-rc2, build 661ac20e

安装成功！

设置docker国内加速器

国内阿里云提供的镜像服务

也可以设置你自己的私服代理服务器或者docker cn提供的国内镜像

登录docker服务器，这个是push镜像到docker hub需要的

[root@ ~]# docker login
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.

Login Succeeded

显示登陆成功，docker + docker-compose 在 centos8 下的环境搭建完成。
