2.1 查看正在运行的容器

// 命令
docker ps

// 输出
CONTAINER ID   IMAGE     COMMAND             CREATED         STATUS         PORTS                                       NAMES
c6197441c5d4   tomcat    "catalina.sh run"   2 minutes ago   Up 2 minutes   0.0.0.0:8080->8080/tcp, :::8080->8080/tcp   tomcat

2.2 查看所有容器

// 命令
docker ps -a

// 输出
CONTAINER ID   IMAGE     COMMAND             CREATED         STATUS         PORTS                                       NAMES

2.3 创建容器

// 命令
docker run -id --name=tomcat \
-p 8080:8080 \
-v $PWD:/usr/local/tomcat/webapps \
tomcat

// -i代表一直运行着，-t代表终端，可以输入命令，简写-it；--name代表容器名字；
// -d代表后台运行创建容器，创建完之后不会立即进入容器，需要通过命令才能进入容器

2.4 进入容器

docker exec -it tomcat /bin/bash

2.5 退出容器

exit

2.6 启动容器

docker start tomcat

2.7 停止容器

docker stop tomcat

2.8 删除容器

docker rm tomcat
// 或者指定容器ID删除
docker rm c6197441c5d4

2.9 删除所有容器

docker rm `docker ps -aq`

2.10 查看容器信息

docker inspect tomcat

3 总结

Docker常用的镜像命令和容器命令基本上就这么多了，大家可以先按之前的文章安装下Docker，然后再执行本文中的一些命令，加深对Docker的理解，有问题，欢迎留言讨论。
