Beginner: How do I configure kong to use my kong.yaml config file?

Beginner Kong user here,

I am attempting to set up Kong as an API gateway. Since we are using the ArgoCD CI/CD GitOps tool, everything must be done declaratively, through manifest files. No commands in the cli.

I am using this kong version:
https://raw.githubusercontent.com/Kong/kubernetes-ingress-controller/v2.9.0/deploy/single/all-in-one-dbless.yaml

How do I configure kong to use my own kong.yaml config file?

Cheers, Mike
