Recipient endpoint not updated when specifying port 8081 in docker-compose

[CR4YZ3R]

First of all thank you for the great mock!

When using this configuration in a docker-compose file

 mujina:
   image: ghcr.io/openconext/mujina/mujina-idp:sha-abedf68
   environment:
     - SERVER_PORT=8081
   ports:
     - 8081:8081

the following error occurs when trying to access the SSO via http://localhost:8081/SingleSignOnService:

SAML message intended destination endpoint 'http://localhost:8081/SingleSignOnService' did not match the recipient endpoint 'http://localhost:8080/SingleSignOnService'

My application uses fastapi as a backend running on port 8080. When sending the request to a fastapi endpoint /SingleSignOnService on port 8080 and redirecting it to localhost:8081 it however does not throw the error mentioned above. That's why I suppose that there might be an issue related to the idp mock. However I am not too familiar with this mock yet, so it might also be a silly mistake on my end ;)

In order to temporarily get it to work, adding - idp.base_url=http://localhost:8081 can be added to the environment part.
