Also, it seems like the official prefect image is configured to display the ascii prefer splash screen (below) and then immediately terminate? The docs say to just use docker-compose, but point to the generic docker-compose website and not an example compose file. Is there an example compose file which has the server configured to keep the server online?

Thanks for using Prefect!!!

This is the official docker image for Prefect Core, intended for executing
Prefect Flows. For more information, please see the docs:
<https://docs.prefect.io/core/getting_started/installation.html#docker>

Generally people start the prefect docker-compose setup with the command

prefect server start

which uses this file: https://github.com/PrefectHQ/prefect/blob/master/src/prefect/cli/docker-compose.yml

Ah, and here I was trying to set the container command to be “prefect server start” and wondering why it was going all foobar. So prefect server start actually invokes docker-compose…hmm…

We added the splash screen in hopes that it would clear up this confusion 😄 is there something we could clarify in the docs?

My confusion was simply not realising that prefect start was launching docker-compose when I assumed it was a local application and I wanted to (myself) put it in a docker-compose. I suppose the confusion comes from an airflow background, in which the main airflow server is run locally and its up to you to abstract it out. In particular, a lot of the questions Ive been posting on here are because our deployment model is to add services into a docker swarm - and if I want to use prefect I need to include its services inside the swarm, rather than having a swarm service which tries to itself start docker compose.
