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?

nice! Ryan will know more but the PREFECT_API_URL doesn't seem to match between code and UI in your image

I agree with Anna - setting

PREFECT_API_URL

<http://172.16.8.65:4200/api>

should make this work for you.

I'll add a comment in the

docker-compose.yml

file that mentions this 🙂

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!
