So you need to set up either S3 or minio for the default configuration to work - I'll mark it as optional, but I'll add a note here & below clarifying that.

So in this case, because of the way I set up the secrets, both YAML blocks would be identical - i'll add a note that this works with either real S3 or minio.

So the reason for the preface was the use of host.docker.internal which I think works out-of-the-box only on MacOS (and maybe Windows) - you need to build the docker images differently and do some docker networking shenanigans on Linux. Do you still think I should remove it? Fine either way!
