I'm wondering how to remove old containers.

(我想知道如何删除旧容器。)

The docker rm 3e552code34a lets you remove a single one, but I have lots already.

(docker rm 3e552code34a可让您删除一个，但我已经有很多。)

docker rm --help doesn't give a selection option (like all, or by image name).

(docker rm --help没有提供选择选项（像所有选项一样，或按图像名称）。)

Maybe there is a directory in which these containers are stored where I can delete them easily manually?

(也许有一个存储这些容器的目录，可以方便地手动删除它们？)

Since Docker 1.13.x you can use Docker container prune :

(从Docker 1.13.x开始，您可以使用Docker容器prune ：)

docker container prune

This will remove all stopped containers and should work on all platforms the same way.

(这将删除所有停止的容器，并且应在所有平台上以相同的方式工作。)

There is also a Docker system prune :

(还有一个Docker系统修剪 ：)

docker system prune

which will clean up all unused containers, networks, images (both dangling and unreferenced), and optionally, volumes, in one command.

(它将在一个命令中清除所有未使用的容器，网络，映像（悬空和未引用），以及可选的卷。)

For older Docker versions, you can string Docker commands together with other Unix commands to get what you need.

(对于较旧的Docker版本，可以将Docker命令与其他Unix命令一起使用以获取所需的内容。)

Here is an example on how to clean up old containers that are weeks old:

(这是有关如何清理已使用数周的旧容器的示例：)

$ docker ps --filter "status=exited" | grep 'weeks ago' | awk '{print $1}' | xargs --no-run-if-empty docker rm
