Hi I adapted your Docker Compose file to Docke

Question

Hi < Ryan Peden> I adapted your Docker Compose file to Docker Swarm and I am having an issue here Orion UI cannot connect to API where should I start looking

Anna Geller · Answer

nice Ryan will know more but the PREFECT API URL doesn t seem to match between code and UI in your image

Ryan Peden · Answer

I agree with Anna setting `PREFECT API URL` to `<http 172 16 8 65 4200 api>` should make this work for you

Ryan Peden · Answer

I ll add a comment in the `docker compose yml` file that mentions this slightly smiling face

And just to clarify you should only need to set this on the Orion container If you are using a container for the agent as well you should be able to leave its PREFECT API URL as <http orion 4200 api> since it can communicate with Orion over the internal Docker network

thanks for being so clear and quick I noticed there are two variables `PREFECT ORION API HOST` set for the prefect orion container `PREFECT API URL` set for the agent container ofc I ll go look them up in the docs but if you can answer me what is the difference and where should they be set Edit I m adding the `PREFECT API URL` in the orion container in addition to the already present `PREFECT ORION API HOST` Edit 2 I checked the github repo and now it s as clear as it gets Thanks
