A CLI app which establishes a connection to a private Google Cloud SQL instance and port-forwards it to a local machine.

Connection is established by running a Google Cloud SQL Auth Proxy pod in a Google Kubernetes Engine cluster which runs in the same VPC network as the private Cloud SQL instance. Connection is then port-forwarded to the local machine, where a user can connect to the instance on localhost. Corresponding workload identity has to be configured in the cluster, with service account which has Cloud SQL Client role on the given SQL instance. Configurations in the app can be saved for practical future usage.

The app relies on local gcloud and kubectl commands which have to be configured and authenticated with the proper Google Cloud user and GKE Kubernetes cluster.
