Description Mrunal Patel 2016-04-04 19:45:01 UTC 
Description of problem:

Create a simple docker image with a VOLUME

FROM busybox
VOLUME ["/var/www"]
CMD ["echo", 'abcd"]

Set the docker daemon config for --no-volumes in /etc/sysconfig/docker:
OPTIONS='--selinux-enabled --log-driver=journald --no-volumes=true'

docker run fails to start when we try to bind mount a volume over the VOLUME:
$ docker run -v ~/tempdir:/var/www <image-name>
It fails with the error that volumes are not allowed when they should in this case.

Version-Release number of selected component (if applicable):
