Docs feedback: external minio storage examples

https://docs.gitlab.com/charts/advanced/external-object-storage/#backups-storage-example

So my team wishes to have a Minio instance running in our AKS cluster. My colleague found some issues with the built in Gitlab-minio helm chart with regards to Azure Blob Storage. So I'm running a standalone stable/minio instance. Ref. backup storage, I can't find a way to refer to the minio storage since Gitlab expects an URL with "https"

Currently I've tried

signature_v2 = False

host_base = 127.0.0.1:9000
host_bucket = 127.0.0.1:9000

and setting host_base and host_bucket to Minio's service name

I get the following error from gitlab unicorn when trying to upload content.

unicorn URI::InvalidURIError (bad URI(is not URI?): "://s3.amazonaws.com:"):
