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 webcentos centos
# 以守护进程的方式运行容器
# docker run 镜像命名
docker run centos
# 指定容器名
docker run --name webcentos centos
# 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
# docker stop 容器名称/容器Id
docker stop webcentos
5、启动容器
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。
