参考文档

官方Docker安装文档:https://docs.docker.com/install/linux/docker-ce/centos

阿里云Docker安装文档:https://yq.aliyun.com/articles/110806

一键安装Docker

安装步骤

删除已安装的Docker

# Uninstall installed docker
sudo yum remove docker \
         docker-client \
         docker-client-latest \
         docker-common \
         docker-latest \
         docker-latest-logrotate \
         docker-logrotate \
         docker-selinux \
         docker-engine-selinux \
         docker-engine

配置阿里云Docker Yum源

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

# Use Aliyun Docker
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

安装指定版本

查看Docker版本:

yum list docker-ce --showduplicates

安装较旧版本(比如Docker 17.03.2) 时需要指定完整的rpm包的包名,并且加上--setopt=obsoletes=0 参数:

# Install docker
# on a new system with yum repo defined, forcing older version and ignoring obsoletes introduced by 17.06.0
yum install -y --setopt=obsoletes=0 \
  docker-ce-17.03.2.ce-1.el7.centos.x86_64 \
  docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch

或安装Docker较新版本(比如Docker 18.03.0)时加上rpm包名的版本号部分:

sudo yum install docker-ce-18.03.0.ce

或安装Docker最新版本,无需加版本号:

sudo yum install docker-ce

启动Docker服务

# Start docker service
systemctl enable docker
systemctl start docker
