How to connect Tunnistamo, Profile and Omahelsinki running on Docker

If you are using Docker to run each of the services above, you need to make sure, that they can access each other from within their containers. In order to do that, you need to make sure, that they are running on the same Docker network:

  1. Make sure, that each project runs on different ports to avoid port conflicts, for example omahelsinki on 80, profile on 8000 and tunnistamo on 8080.

  2. Add network definition to tunnistamo's docker-compose.yml:

    version: '3'
services:
    postgres:
        ...
        networks:
            - net
        
    django:
        ...
        networks:
            - net
        
networks:
    net:
        driver: bridge

  3. Connect omahelsinki and profile to tunnistamo's network, by adding this code snippet at the end of omahelsinki's and open-city-profile's docker-compose.yml files:

    networks:
    default:
         external:
             name: tunnistamo_net

    The name tunnistamo_net comes from the name of the folder, where your tunnistamo code is combined with the name of the network. Change those according to your setup, if needed.

  4. Now you can access tunnistamo from within other docker containers with http://tunnistamo-backend:<port> url, i.e. Tunnistamo's django container's name.

  5. Your tunnistamo instance needs to have at least one social media login method configured, for example Github. As the authentication flow will be initiated by omahelsinki using the http://tunnistamo-backend:<port> link, when tunnistamo will call this social media platform it will pass this link as the origin and as the base of the callback, so the oauth app in your social media should be configured to use this precise link:

    github-oauth-app-example

  6. When the user authenticates through the social media, it will redirect them back to the http://tunnistamo-backend:<port> link, so your machine should now that this is your local tunnistamo instance: add tunnistamo-backend to your computer's localhost aliases. To do this on UNIX-like systems open /etc/hosts and add it:

    127.0.0.1    localhost tunnistamo-backend
