docs: clarify required variables for starting Kratos

[tomascharad]

Describe the bug

When I pull the image from Docker Hub and try to run it, it asks me to include the file

Reproducing the bug

Steps to reproduce the behavior:

Server logs

Server configuration

Expected behavior

It should run by itself, as stated in docs: https://www.ory.sh/kratos/docs/reference/configuration.
"If file $HOME/.kratos.yaml exists, it will be used as a configuration file which supports all configuration settings listed below."

By saying 'If file exists' it shouldn't be required.

Environment

• Version: 16-04-2020 latest version
• Environment: Docker

Additional context

I'm running the instance on heroku, do you know how could I make it run without making any modifications to the original image?

[aeneasr]

Could you please provide the server logs? I am asking because it is possible to run Kratos without a configuration file, but you still need to provide the required configuration values via env vars.

I'm running the instance on heroku, do you know how could I make it run without making any modifications to the original image?

Heroku will probably not be sufficient as it does not have (afaik) the ability to expose a port only on an internal / privileged network or alternatively with a security system in front, which is required for ORY Kratos' Admin API Port.

Ok with heroku, I''ll try another service, If i run this on my local computer I get this.

Could you please help me with setting up on my local @aeneasr?

These are the heroku logs

On my local computer I've cloned the repo and build the image with make docker and in heroku I've just sent the image from Docker Hub.

PS: I've made it work, just entered all the requried config variables as ENV variables.

[aeneasr]

Perfect! I'll be closing this then, yes?

Hi @aeneasr,

I think that at least you should update the docs before closing the issue, so people understand that tweaking the .kratos.yaml is a must, or at least setting up the ENV variables, which is not very clear on the docs and how to do so.

But for me everything is ok. Thanks.

[aeneasr]

Yup, makes sense!
