centOS 安装Docker

今天试着在CentOS 8.0上面安装了一下Docker，现分享给大家。 

1.首先安装依赖包

#sudo yum install -y yum-utils  device-mapper-persistent-data  lvm2

#sudo yum-config-manager  --add-repo   https://download.docker.com/linux/centos/docker-ce.repo

#sudo yum install docker-ce docker-ce-cli containerd.io

安装过程如果报错：Problem: package docker-ce-3:19.03.4-3.el7.x86_64 requires containerd.io >= 1.2.2-3 那就先装新版的 containerd.io

#dnf install https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm

 

2.再装剩下两个

#sudo yum install docker-ce docker-ce-cli

#sudo systemctl start docker

 

3.查看docker版本

#docker --version

 

4.设置Docker开机自动启动

#sudo systemctl enable docker
