# 查询运行中的容器
$ docker ps 

# 查看所有的容器
$ docker ps -a

# 启动|停止|重启|杀死容器 anyesu-container
$ docker start | stop | restart | kill anyesu-container

# - docker rm [OPTIONS] CONTAINER [CONTAINER...]
# 删除Id为c6e7471292e0的容器
$ docker rm c6e7471292e0

# - docker inspect [OPTIONS] NAME|ID [NAME|ID...]
# 检视Id为97763bd57c69的容器
$ docker inspect 97763bd57c69

# - docker top CONTAINER [ps OPTIONS]
# 查看容器中正在运行的进程
$ docker top 97763bd57c69

# - docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]
# 保存容器为镜像
$ docker commit tomcat wangwei01/tomcat:1.0

# 根据Dockerfile 构建
$ docker build -t [image_name] [Dockerfile_path]

$ docker exec -it {{containerName or containerID}} bash
$ docker exec -i  {{containerName or containerID}} bash
$ docker exec -t  {{containerName or containerID}} bash
$ docker exec -d  {{containerName or containerID}} bash
  • 只用 -i 参数，由于没有分配伪终端，看起来像pipe执行一样。但是执行结果、命令返回值都可以正确获取
  • 只用 -t 参数，则可以看到一个 console 窗口，但是执行命令会发现由于没有获得stdin的输出，无法看到命令执行情况
  • 使用 -it 时，则和我们平常操作 console 界面类似，而且也不会像attach方式因为退出，导致整个容器退出
  • 使用 -d 参数，在后台执行一个进程。如果一个命令需要长时间进程，会很快返回

Docker run
