Hi 👋 , Any tips on how I might debug this 🤔

I'm no expert but that error suggests to me that there's already something running on the system that's bound to port 5432, so prefect's postgres instance can't start

Thanks, so I did that and killed the process and cleaned all docker containers and images.

Well it says what is wrong doesn’t? 😅 Your disk is full. No kidding, you probably should clean up your docker (

docker system prune

check docs for everything it try to do), or increase your docker volume (in case of mac, not sure how windows handles it)

The thing is, i do have plenty of GBs of space (200+) that’s available - hence my confusion : /

Is that the disk of your machine or what docker has access to? Because those are different things.

Ubuntu is what I am using. The most “recent” error i saw is this

Error: (psycopg2.OperationalError) could not translate host name "postgres" to address: Name or service not known

Woah that is alot, no idea, not running prefect in production yet. But I could imagine if you use the LocalResult (or some other Result mechanism) it takes up space, if that is the data you are referring to, see if you can disable it or clean it up after a run?

I don’t know what’s safe to delete. This is not

--volume-path

but instead it’s the task

flow.storage = Local(directory='/this/location)

Don’t take my word for it, but AFAIK the results is only used for caching. Such that you can restart at a later point in the flow, without having to recalculate earlier tasks. Best to check docs to be sure 🙂
