Unable to bind volume in read-only mode #186

I am able to mount a volume test with the command hyper run -it -v test:/test ubuntu.

If I then append :ro to the mount command, hyper run -it -v test:/test:ro ubuntu, I get the following error:
hyper: Error response from daemon: Bad request parameters: invalid volume bind parameter.

I am using the hyper.sh platform.
