Spanner operation client for Cloud Spanner Administrator.
This repo is based on sample-controller.
This is an experimental project of my own practice creating custom controller.
- Create/Update/Delete instance
- Create/Delete database
- Scale instance node count
⚡ Notes
Currently I've only tested on my local machine by using minikube.
