centos8-stream安装docker(最新)
安装依赖包
sudo yum install -y yum-utils
使用国内镜像源
sudo yum-config-manager \
--add-repo \
https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sudo sed -i 's/download.docker.com/mirrors.aliyun.com\/docker-ce/g' /etc/yum.repos.d/docker-ce.repo
需要测试版docker 执行:
sudo yum-config-manager --enable docker-ce-test
安装docker

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

输出如上则安装正确
镜像加速
如果在使用过程中发现拉取 Docker 镜像十分缓慢，可以配置 Docker 国内镜像加速
在 /etc/docker/daemon.json中写入(没有就新建)
{
"registry-mirrors": [
"https://hub-mirror.c.163.com",
"https://mirror.baidubce.com",
"https://xxxxxx.mirror.aliyuncs.com/"
]
}
注意json格式
重启服务
sudo systemctl daemon-reload
sudo systemctl restart docker
执行docker info结果中包含下面内容则配置成功
Registry Mirrors:
https://hub-mirror.c.163.com/
https://mirror.baidubce.com/
https://xxxx.mirror.aliyuncs.com/
安装docker-compose
二进制文件 x86_64
$ sudo curl -L https://github.com/docker/compose/releases/download/1.27.4/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
# 国内用户可以使用以下方式加快下载
$ sudo curl -L https://download.fastgit.org/docker/compose/releases/download/1.27.4/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
$ sudo chmod +x /usr/local/bin/docker-compose
docker-compose -v
