使用
docker ps来获取容器ID。
然后
docker inspect -f '{{ .Mounts }}' containerid例：
1号航站楼
$ docker run -it -v /tmp:/tmp ubuntu:14.04 /bin/bash
2号航站楼
$ docker psConTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESddb7b55902cc ubuntu:14.04 "/bin/bash" about a minute ago Up about a minute distracted_banach$ docker inspect -f "{{ .Mounts }}" ddb7map[/tmp:/tmp]输出
map[/tmp:/tmp]
显然是由于使用 Go 语言来实现docker命令工具。
在
docker inspect没有命令
-fformat相当冗长。由于它是JSON，因此您可以将其通过管道传递到python或nodejs并提取所需的任何内容。
