centos8 安装 docker

centos 安装docker 

官方参考地址：https://docs.docker.com/install/linux/docker-ce/centos/

里面包含包下载地址： https://download.docker.com/linux/centos/7/x86_64/stable/Packages/ 

 

安装依赖

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

 

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

 

再装剩下两个

sudo yum install docker-ce docker-ce-cli

 

sudo systemctl start docker

 

docker --version

 

开机自启

sudo systemctl enable docker
