Environment variables naming scheme

Hi,
We can pass some data to hydra via environment variables - awesome and very useful for docker-compose deployment.

Shouldn't the env variables have a common prefix "HYDRA_" to avoid collisions?

Good point, that really depends on the environment. In a docker environment, there should be close to zero collisions, because you set env vars per container. Some of the env vars like PORT and HOST are actually best practice because they make hydra run on heroku/cloud foundry/flynn/dokku/... out of the box.

However, stuff like tls paths could be scoped - did name collision happen in your environment?

[janekolszak]

Well if your container has only Hydra inside then you're right.

You can also set env vars with ENV=foo hydra - so i think we should be good :)
