Hmm, I don't know enough to give you a confident answer yet. However, I can provide you with some information on Octavia CLI and deploying Airbyte on Kubernetes that might help you. Octavia CLI is a command-line interface for managing Airbyte resources like sources, destinations, and connections using YAML files. It's useful for version controlling configurations, automating deployment pipelines, and managing multiple Airbyte instances [source](). You can find more information on Octavia CLI commands in the [CLI documentation](https://docs.airbyte.com/cli-documentation). For deploying Airbyte on Kubernetes, you can use Helm. There are guides available for setting up a local Kubernetes cluster using [Docker Desktop (Mac)](https://docs.docker.com/desktop/kubernetes), [Minikube](https://minikube.sigs.k8s.io/docs/start), or [Kind](https://kind.sigs.k8s.io/docs/user/quick-start/). For deploying on GKE, you can follow the [GKE cluster creation guide](https://cloud.google.com/kubernetes-engine/docs/how-to/creating-a-zonal-cluster) [source](https://docs.airbyte.com/deploying-airbyte/on-kubernetes-via-helm). Unfortunately, I don't have specific information on how to integrate Octavia CLI with GKE and GitHub Actions in the provided extracts. I recommend checking the [Airbyte documentation](https://docs.airbyte.com) and joining the [Airbyte community Slack](https://airbyte.slack.com/) for further assistance.
