docker安装方式：
vim get-docker.sh //创建 get-docker.sh 脚本，把上面的脚本内容贴进去，然后保存退出。 sh get-docker.sh --mirrot Aliyun //使用刚刚创建的脚本进行安装 然后坐等安装完成。 安装完成后启动docker systemctl start docker //启动docker systemctl enable docker //设置开机启动docker 如果启动成功，则可用如下命令查看运行中的容器（刚开始是没有容器的）： docker ps //查看运行的容器（刚开始是没有容器的）
为了方便下载镜像，可以自己配置镜像源为阿里云的镜像源，方法如下：
vim /etc/docker/daemon.json //创建daemon.json文件 将如下内容写入文件，然后保存退出，并重启docker { "insecure-registries": ["aegis-paas.aliyun.com:5000","aegis-saas.aliyun.com:5000","aegis-inner.aliyun.com:5000","aegis-base.aliyun.com:5000"], "registry-mirrors": ["https://registry.docker-cn.com"] }
重启docker
systemctl restart docker //重启docker docker ps //查看运行的容器 docker -v //查看docker 版本
docker 常用命令
docker images //查看当前服务器所有镜像 docker ps //查看当前服务器正在运行的容器 docker ps -a //查看当前服务器所有容器 docker exec -it 容器ID /bin/bash //进入指定容器 exit //退出容器 docker rm 容器ID //删除指定容器 docker rmi 镜像ID //删除指定镜像，正在使用的容器的镜像不能删除 docker save 镜像ID > 镜像名.tar //打包指定镜像为 镜像名.tar docker load < 镜像名.tar //加载指定镜像压缩包 docker tag 源镜像ID 镜像名[:tag] //为指定镜像打标签
