Steps to reproduce:
- Create a volume with the new
volumecommand:
docker volume create --name hello
> hello
docker volume ls
> DRIVER VOLUME NAME
> local hello
- Then "mount" it:
docker run --rm -it -v hello:/world busybox sh
/ # touch world/foobar
/ # exit
- Then look for volume:
docker volume ls
> DRIVER VOLUME NAME
This seems dangerous behavior given that volumes are considered the persistent component of the system.
