Getting "forbidden"

[esnible]

When I first brought up Boatyard the web UI just showed 'Forbidden'

To fix it I nsenter the container and did "chown -R www-data /app/html". It is unclear what is causing this, and a colleague here reports the same thing with an nginx container he is using. I got the idea to chown the files to the nginx user from a six-year-old blog post at http://nicholasorr.com/blog/2008/07/22/nginx-engine-x-what-a-pain-in-the-bum/
