Hi, I'm running into, what is probably a very simple issue with docker networking. Setup: • Orion Server (running locally: 127.0.0.1:4200) • Prefect Agent (running locally) • Airbyte Server (running locally: 127.0.0.1:8000) • Docker Infra Block - Docker running locally The agent can see the server. I can create and apply a deployment. On starting the flow: • The agent kicks off. • The agent creates the docker image. • The agent applies any pip requirements from block env setting. • It then fails with

ConnectionRefusedError: [Errno 111] Connect call failed ('127.0.0.1', 4200)

I'm assuming the flow running in the docker container cannot see the orion server on port 4200, however, I'm not sure what to do to fix that. No doubt the next failure will be accessing the Airbyte server, but I'm not there yet. Any help is much appreciated.

Hi Steven, How did you set this up, and did you follow a tutorial of any sort? How is docker being setup and exposed? What happens if you shell into the docker image, and try to curl 127.0.0.1:4200? Do you have logs (flow run logs, agent logs) ? To that point above, can you turn up logging to DEBUG,

prefect config set PREFECT_LOGGING_LEVEL=DEBUG

and share agent logs Also, where is the “ConnectionRefusedError” occurring - is this from the local docker agent?

I didn't follow a tutorial. I've read a lot of the documentation, and I'm just building up bit by bit from a fully local stack to a dockerised stack (all local) to eventually move it all to the cloud. It is just part of a learning exercise as part of preparing for some consultancy work.

so you basically want to run everything local, agent, server, and docker ; you want to be able to run a flow from the UI (running locally on 4200) to have a docker container start with the flow (which is also local). Is that accurate?

Yes: • Orion Server (running locally: 127.0.0.1:4200) • Prefect Agent (running locally) • Airbyte Server (running locally: 127.0.0.1:8000) • Docker Infra Block actually running the flow (Docker running locally)
