- Kong configuration (registered APIs/Plugins & configuration file)
    Haven't touched these so what ever is shipped with the container.
- Operating System
    Docker running on Ubuntu 16.04.2 LTS on AWS VPS.

Hmm seems my problems came from running everything from docker-compose run

Originally I did this because I couldn't run kong migrations up from docker exec, but after running that with docker-compose run, I can reload with docker exec -it kong reload without problems.
