一、安装

sudo yum install -y yum-utils

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

sudo yum-config-manager --enable docker-ce-edge

  sudo yum install docker-ce

  查看版本 

docker -v

二、卸载

  yum remove docker-ce

yum remove docker docker-common docker-selinux container-selinux docker-engine

  sudo rm -rf /var/lib/docker

如果不行尝试下面

 yum list installed | grep docker

  sudo yum -y remove docker-engine.x86_64

  rm -rf /var/lib/docker

 

三、意外

   如果出现如下错误

 Error: docker-ce-selinux conflicts with 2:container-selinux-2.10-2.el7.noarch

 You could try using --skip-broken to work around the problem  You could try running: rpm -Va --nofiles --nodigest
