常用命令：
--- 镜像 ---
1、docker镜像检索
# docker search 镜像名
docker search centos
2、docker镜像下载 （等待时间不是一般久）
# docker pull 镜像名
docker pull centos
3、docker镜像列表
docker images
4、docker镜像删除
# docker rmiimage-id (镜像id)
docker rmi 34336sdf12
5、删除所有镜像
docker rmi$(docker images -q)
--- 容器 ---
1、创建并运行容器
# docker run 镜像命名
docker run centos
# 指定容器名
docker run --name webcentoscentos
# 以守护进程的方式运行容器
docker run --name webcentos -d centos
2、容器列表
docker ps
3、容器状态
docker ps -a
4、停止容器
# dockerstop 容器名称/容器Id
docker stop webcentos
5、启动容器
# docker start 容器名称/容器Id
docker start webcentos
6、删除容器
# docker rm 容器id
docker rm 235483s15c
7、删除所有容器
docker rm $(docker ps -a -q)
8、容器日志
# docker logs 容器名称/容器id
docker logs webcentos
9、登陆容器
# docker exec -it 容器名称/容器id/bin/bash
docker exec -it webcentos /bin/bash
其中， -t 选项让Docker分配一个伪终端（ pseudo-tty）并绑定到容器的标准输入上， -i 则让容器的标准输入保持打开。
