How do I access exposed ports on my Docker containers from outside the VM?
So, I've installed Shipyard by following the Quickstart guide, and I now have a container running called `shipyard` which exposes a HTTP server on 0.0.0.0:8000. I can access it just fine from within the droplet using curl, but I can't connect to it over the Internet. I've tried disabling ufw; as well as enabling it, setting DEFAULT_FORWARD_POLICY="ACCEPT" in /etc/default/ufw and allowing port 8000. I've tried using multiple VMs in multiple regions, even. I'm using a newly-created droplet with the Docker image.
