Hello! I’m working on my first Tutor plugin, [feat: adds superset docker services and open edx integrations by pomegranited · Pull Request #1 · open-craft/tutor-contrib-superset · GitHub](https://github.com/open-craft/tutor-contrib-superset/pull/1), which sets up Apache Superset and allows users to use Open edX SSO to authenticate to the app. To set up SSO, I need to know the full root LMS URL: e.g. - [http://local.overhang.io:8000](http://local.overhang.io:8000) in `tutor dev`, or - [http://local.overhang.io](http://local.overhang.io) in `tutor local`. The variable I’m trying to set is here: [`SUPERSET_OAUTH2_BASE_URL`](https://github.com/open-craft/tutor-contrib-superset/pull/1/files#diff-34becf7bb60402c8556a9bc64d435f02a3c47ba1eb7c52606239bcc021c5dae6R28) I can get the base domain configured from `LMS_HOST`, and I can figure out whether it’s http or https from `ENABLE_HTTPS`. But I can’t seem to find the variable that tells me whether there’s a port that needs to be added to the hostname. I’ve tried several things, but nothing has worked with the plugin.py script so far. - The variable `JWT_COMMON_ISSUER` is available when my plugin.py is running, but it only contains the correct value when running `tutor local`; it doesn’t get the `:8000` port appended for `tutor dev`. - Variables like `LMS_ROOT_URL` or `COMPOSE_PROJECT_NAME` are not available when my plugin.py is running. - I’m adding patches to `ENV_PATCHES["local-docker-compose-services"]`, so I thought maybe there was an `ENV_PATCHES["dev-docker-compose-services"]` equivalent for dev – doesn’t seem to be? - I looked at other plugins like tutor-discovery and tutor-ecommerce, and they hardcode the LMS provider URL in their django dev/prod settings file templates. I can’t really do that with my plugin, because Superset doesn’t have a notion of running in dev vs prod environments. How do other people solve this issue? ---

I can’t really do that with my plugin, because Superset doesn’t have a notion of running in dev vs prod environments. Yes, this is exactly how other plugins handle the situation. The `:8000` part is just hard-coded in dev settings. I understand that you cannot do this here in your plugin. So instead I would suggest that you pass the full LMS url to your superset container via an environment variable. This variable will be different in production and development. > [@jill](#): > > I’m adding patches to `ENV_PATCHES["local-docker-compose-services"]`, so I thought maybe there was an `ENV_PATCHES["dev-docker-compose-services"]` equivalent for dev – doesn’t seem to be? Pretty close 🙂 It’s actually “[local-docker-compose-dev-services](https://docs.tutor.overhang.io/reference/patches.html#local-docker-compose-dev-services)”. I can understand why this would not be a very intuitive name… To sum it up, you need to add this value to the “local-docker-compose-services” production patch: ```auto environment: - LMS_FULL_URL = "{% if ENABLE_HTTPS %}https{% else %}http{% endif %}://{{ LMS_HOST }}" ``` And this one to the “local-docker-compose-dev-services” patch: ```auto environment: - LMS_FULL_URL = "http://{{ LMS_HOST }}:8000" ``` ---

> [@regis](#): > > Pretty close 🙂 It’s actually “[local-docker-compose-dev-services](https://docs.tutor.overhang.io/reference/patches.html#local-docker-compose-dev-services)”. Ah perfect @regis ! That was the piece of information I needed. I still had to wrestle with some escaping because I was doing (probably too) fancy things with the docker-compose config, but [it’s working now](https://github.com/open-craft/tutor-contrib-superset/pull/1/files#diff-34becf7bb60402c8556a9bc64d435f02a3c47ba1eb7c52606239bcc021c5dae6R184-R203)! Thank you!
