解决 docker pull 拉取镜像因版本问题导致的拉取失败

在Centos7中，yum源存在着旧版本的docker，我们需要对其升级，以确保正常使用。

卸载旧版本的docker

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

安装仓库添加工具

yum install -y yum-utils

为Docker设置仓库

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

安装 Docker Engine

yum install -y docker-ce docker-ce-cli containerd.io

启动

systemctl start docker
