-> Create a project -> Enable the GKE API / get access -> Deploy 2 containers (metabase/metabase:official and postgres) -> Put the environment variables under the containers -> Deploy the workload.

GKE will take the environment variables that you entered and gather them into a secrets file that you can inspect
To set the port forwarding on the load balancer I needed to edit the file by hand:
