centos7 快速部署docker-ce最新版

1.卸載老的docker

yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

2.安裝依賴

yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2

3.添加docker的yum源

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

4.使用yum方式安裝docker

yum install docker-ce docker-ce-cli containerd.io
如果需要指定版本安裝
$ yum list docker-ce --showduplicates | sort -r
$ sudo yum install docker-ce-<VERSION_STRING> docker-ce-cli-<VERSION_STRING> containerd.io

5.啓動docker

sudo systemctl start docker

6.測試docker是否安裝成功

docker run hello-world
