I think I had that same error regarding numbers and strings: if you’re using that docker-compose file you need to put “” quotation marks around the number 4 in line 7, so it reads max-file: “4”
You’re probably better off using the docker-compose.yml from the Ansible repo as your starting point and working from there, the one in the main repo is a bit of a mess as it’s being actively worked on at the minute.
Yeah I remember Patrick Moore always pronouncing it like that (with a hard g).
Although Wikipedia suggests that the name originally comes from the Arabic for Orion, al-Jauzā', so the colloquial pronunciation is probably more correct.
