How do I access exposed ports on my Docker containers from outside the VM?

April 17, 2014 8.1k views
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 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.

You need to set up a proxy to forward the connection on. We have a tutorial explaining how to use nginx to do that:

That should point you in the right direction. Let us know if you need any more help!

In this DigitalOcean article, our goal is to learn about creating a docker container from a base image and building it to run Nginx (layer by layer). Later, following the steps from the beginning, we create a Dockerfile to automate the process using a custom input file for configurations. In the end, using this Nginx docker image, it becomes possible to create self-contained sandboxes running Nginx, which can be used to serve "dockerised" applications.
