moby: Cannot mount a volume with '/' in it's name
ErrorCodeVolumeName error is generated: “%s includes invalid characters for a local volume name, only [a-zA-Z0-9][a-zA-Z0-9_.-] are allowed”
Possible root cause: the constant in https://github.com/docker/docker/blob/master/utils/names.go lacks forward slash in regexp.
const RestrictedNameChars = [a-zA-Z0-9][a-zA-Z0-9_.-]

I’ve just bitten by this too. Any chance the message could be fixed to reflect the fact that paths are allowed but must be absolute?
Clay, problem is resolved, thank you!
I was violating this requirement: The host-dir can either be an absolute path or a name value.
In my case host volume path was relative. I was actually deceived by the error message:
Error response from daemon: volumes/adms1/app includes invalid characters for a local volume name, only [a-zA-Z0-9][a-zA-Z0-9_.-] are allowed
For those it is not clear, here is a great explanation from #34532 by @thaJeztah https://github.com/moby/moby/issues/34532#issuecomment-322738970 about the invalid characters in the volume name.
should be
note that paths like
~/fooor$HOME/fooare expanded to an absolute path (/home/username/foo) by your shell, before invoking docker.Or in this case, docker-compose. It worked with ${PWD} in the docker-compose.yml file.
