This makes it much easier to run inside a docker container.

I want to resolve this issue. Is there any suggestion to do this task.

Take a look around https://github.com/oauth-io/oauthd/blob/master/src/core/config.coffee. Something like this should do the trick (L11):

config.host_url = config.host_url or process.env['OAUTHD_HOST_URL']
config.port = config.port or process.env['OAUTHD_PORT']
# etc...

Thanks for investigating the issue !

Thanks @thyb
I have got it. How can I start it? Will you make a separate branch for me?
