Question

When I stop my prefect local server and restart the flows I registered and projects created are gone Are they not persisted in the backend like the cloud

Hi < Chandra Manginipalli> I don t believe we have a persistent volume built into the Docker compose by default so yes I think that is expected behavior

interesting I read local server stores flow metadata in a Postgres database and exposes a GraphQL API at <https docs prefect io api latest |here> and thought postgres is used by default for storage

Chandra Manginipalli · Answer

I was under the impression it stores flow runs etc in that postgres storage and not on a file system through volume did I misunderstand

Dylan · Answer

Yes but when you tear down your images I m not sure that the Postgres database persists unless you configure a persistent volume

Dylan · Answer

So as long as `prefect server start` of which part is `docker compose up` is running things will persist

Dylan · Answer

If your postgres image is restarted I m not sure that data persists unless you set up a persistent volume

Chandra Manginipalli · Answer

Chandra Manginipalli · Answer
