Operación de contenedores
docker inspect f6d0b4767a6c #获取镜像
docker ps #查看容器
docker start 24482430b294 #启动容器
docker ps -a #查看状态为up
docker run -d centos:7 /bin/bash -c ls /
#这条命令，每运行一个就会多一个镜像，因为run可以快捷创建镜像启动镜像服务
docker run -d centos:7 /bin/bash -c "while true;do echo hello;done"
docker exec -it de052bd8c791 /bin/bash
exit 退出容器
docker run -itd nginx:latest /bin/bash #启动容器
cat /opt/nginx.bak | docker import - nginx #导出指定的镜像，到指定的目录中
docker export e1da8b9e3b9d > /opt/nginx.bak:web #从指定的目录中导入指定的镜像
docker rm 镜像号 #删除容器
docker ps -a | awk '{print"docker rm "$1}' | bash #批量删除容器
