Prefect permission denied

Documenting a solution to an error during the installation of Prefect: https://docs.prefect.io/core/getting_started/installation.html

At step:

sudo prefect server start

Error:

I'm on Arch Linux using community package Docker 1:20.10.7-1.
Running a docker on my install requires sudo, for example sudo docker run hello-world works fine.

So my intuition was that this file /tmp/docker-compose.yml would need to be readable by root.

So I changed its permissions:

sudo chown -R root:root /tmp/docker-compose.yml

And now the server start works without error and I can load the web interface.
