mkdir: cannot create directory ‘/app/vendor/bundle’: Permission denied

I've just installed nanobox and docker for the first time. Following the instructions in the readme here gives me this error:

sudo nanobox run rails s Preparing environment :

---

• HEADS UP:
• This is the first build for this project and will take longer than usual.
• Future builds will pull from the cache and will be much faster.

---

Building runtime : ✓ Starting docker container ✓ Preparing environment for build ✓ Gathering requirements ! Mounting cache_dirs

! FAILED TO MKDIR -P /APP/VENDOR/BUNDLE !

Exit 1

Command su - gonano -c "mkdir -p /app/vendor/bundle"

Output mkdir: cannot create directory ‘/app/vendor/bundle’: Permission denied

Error : failed to execute hook (mount) on b38eae740846cc02e8a3145cfd6a66702f83da9910c8383c683cbf15c54bb779: util:Exec:/opt/nanobox/hooks/mount: bad exit code(1): Context : failed to build the code

Any idea what's causing it?

It looks like a permissions issue with the container. Can't seem to replicate it on my Ubuntu 17.04 workstation.

Are you still getting this error?
