# ps
用法
Usage: docker ps [OPTIONS]
List containers
-a, --all=false Show all containers (default shows just running) --before= Show only container created before Id or Name -f, --filter=[] Filter output based on conditions provided --help=false Print usage -l, --latest=false Show the latest created container, include non-running -n=-1 Show n last created containers, include non-running --no-trunc=false Don't truncate output -q, --quiet=false Only display numeric IDs -s, --size=false Display total file sizes --since= Show created since Id or Name, include non-running
例子
$ sudo docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES b448f729a0b0 centos "/bin/bash" 4 days ago Exited (137) 4 days ago pensive_wilson 54c7b6d6632e centos "/bin/bash" 4 days ago Exited (0) 3 days ago adoring_wozniak
利用筛选器筛选出exied状态时0的容器：
$ sudo docker ps -a --filter 'exited=0'
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
8d92293a65e9 registry.liugang/centos "/bin/bash" 7 days ago Exited (0) 5 days ago web
8410f389ea65 registry.liugang/centos "/bin/bash" 7 days ago Exited (0) 7 days ago test_link
- 总结
-a参数列出所有状态的容器， -l列出最新创建的容器，包括停止运行状态的容器。
# kill
用法
Usage: docker kill [OPTIONS] CONTAINER [CONTAINER...]
Kill a running container using SIGKILL or a specified signal
--help=false Print usage -s, --signal=KILL Signal to send to the container
例子
$ sudo docker kill pensive_wilson pensive_wilson
这将停止该容器
- 总结
结合ps命令，可以做到kill所有正在运行的容器：
$ sudo docker kill $(sudo docker ps -a -q)
# rm
用法
Usage: docker rm [OPTIONS] CONTAINER [CONTAINER...]
Remove one or more containers
-f, --force=false Force the removal of a running container (uses SIGKILL) --help=false Print usage -l, --link=false Remove the specified link -v, --volumes=false Remove the volumes associated with the container
例子
$ sudo docker rm pensive_wilson pensive_wilson
这将删除一个已经停止运行的容器，若容器正在运行，则将会使docker报错，停止容器再删除，或者加上-f参数强制删除（不建议）。
- 总结
类似的我们也结合ps删除所有容器：
$ sudo docker kill $(sudo docker ps -a -q)
...
...
...
$ sudo docker rm $(sudo docker ps -a -q)
...
...
...
要清空容器，首先要保证没有容器在运行。
# rmi
用法
Usage: docker rmi [OPTIONS] IMAGE [IMAGE...]
Remove one or more images
-f, --force=false Force removal of the image --help=false Print usage --no-prune=false Do not delete untagged parents
例子
$ sudo docker rmi centos:6.5 ... ... ...
总结
要区分rm于rmi多用法。 与docker images命令配合来清空镜像：
$ sudo docker rmi $(sudo docker images -a -q)
