docker最新安装、完全卸载、常用命令及制作并推送镜像 Docker

Docker:是一个开源的引擎，可以轻松的为任何应用创建一个轻量级的、可移植的、自给自足的容器。开发者在笔记本上编译测试通过的容器可以批量地在生产环境中部署，包括VMs（虚拟机）、bare metal、OpenStack 集群和其他的基础应用平台。

完全卸载：

sudo yum list installed|grep docker sudo yum remove containerd.io.x86_64 docker-ce.x86_64 docker-ce-cli.x86_64 sudo rm /etc/yum.repos.d/docker*.repo sudo rm -rf /etc/systemd/system/docker.service.d sudo rm -rf /var/lib/docker sudo rm -rf /var/run/docker sudo rm -rf /run/docker sudo rm -rf /etc/docker

最新安装：

sudo yum install -y yum-utils device-mapper-persistent-data lvm2 sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo sudo yum makecache fast sudo yum -y install docker-ce sudo systemctl start docker sudo systemctl enable docker vim /etc/docker/daemon.json

}
