Am stuck at enabling artifact caching in Google Cloud Storage. The documentation is abstruse as they do not point to how to configure the gitlab-runner for Kubernetes cluster.

I am using gitlab-ci and created a google-kubernetes cluster for auto-dev-ops. In the same am trying to create two environments staging.domain.com and domain.com.

When trying to build and deploy, the artifacts are being downloaded every time. To enable caching they want to edit the toml file. However, since I have enabled the Kubernetes runner integration thru UI. Am not sure how to find it.
