add Dockerfile & Consul

[natebrennand]

• Docker
  • installed in vagrant
  • Dockerfile added
• Consul
  • installed in vagrant
  • if not DEBUG, the app is configured from Consul
• Upgrades Vagrant to an Ubuntu 14.04 image
• pep8 compliance

@thebrianzeng, Consul is what I was suggesting. It's simple to use with python. It'll make things simple when multiple services are utilizing the same database instance as well as simplify getting Docker work easily since you just expose the port that Consul is running on for configuration. Then there is no state maintained in the Docker image.

i'll look into Consul more deeply on friday - seems pretty promising.

So I added code to use gunicorn & updated the vagrant so that Docker works on it (had to go from 12.04 -> 14.04). If you guys are fine with Consul, I'll add that integration as well and then this should be good to go. As is, a lot of environment variables have to be passed in through the docker run command

I think Consul's a good idea - go for it

@natebrennand any ideas?

[natebrennand]

did you trash your old vagrant? you need to do vagrant destroy then vagrant up

[thebrianzeng]

further issue: when i run `sudo docker ps' i only get

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

[natebrennand]

that's not an issue, it just means that you aren't running any containers

[thebrianzeng]

i got that after doing sudo docker run --net=host -d density

[natebrennand]

​​ make sure you have it working before you use the -d flag. That backgrounds it, idk how to access the image logs unless you kept track of the ID. You may need to use sudo docker stop $ID to end it after you start it up.
