centos8安装docker和docker-compose

1、首先更新一下：yum -y update
2、centos8默认使用podman代替docker，所以需要containerd.io，那我们就安装一下就好了

yum install https://download.docker.com/linux/fedora/30/x86_64/stable/Packages/containerd.io-1.2.6-3.3.fc30.x86_64.rpm

3、安装一些其他依赖

yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum makecache

4、安装docker-ce

dnf -y  install docker-ce --nobest

5、开启Docker服务并设置开机自启

systemctl start docker && sudo systemctl enable docker

6、测试，如输出下图结果则安装成功

7、Docker-compose 安装

//推荐方法一# 方法一 (Refer to: https://docs.docker.com/compose/install/)
sudo curl -L "https://github.com/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

# 方法二 (Refer to: https://docs.docker.com/compose/install/#install-using-pip)
sudo pip3 install docker-compose

# 测试, 如输出下图结果则安装成功
docker-compose --version
# 输出：docker-compose version 1.27.4, build xxx
