Im kinda new with some infraestructure things, ive made the deploy of datahub in a kubernetes pod yesterday but now im trying to enable the sso from google on datahub, but im stuck at the part that i must access the pod, and i dont have any clue on how to do that.

What's the cloud environment (e.g. AWS, GCP) if any? Essentially you have to expose the datahub-frontend service. Here's an example using AWS EKS https://datahubproject.io/docs/deploy/aws/#expose-endpoints-using-a-load-balancer
