Summary

Unable to mount rexray/s3fs volume to docker container

Bug Reports

I am able to install the Docker plugin successfully and successfully create volumes. However, when I try to mount the volume to a container using docker run -it --volume-driver=rexray/s3fs -v myVol:/test busybox, I get the following error message:

C:\Program Files\Docker Toolbox\docker.exe: Error response from daemon: error while mounting volume '/mnt/sda1/var/lib/docker/plugins/72070f05ca2941b6ed377bfff1ab116acd4cfd7410a98a01510a47c841517e4f/rootfs': VolumeDriver.Mount: docker-legacy: Mount: myVol: failed: error mounting s3fs bucket.
