Schedule Start/stop on GCP SQL Instance - google-cloud-sql

Question

I want to schedule my SQL Instance of GCP.
How to Trigger start/ stop SQL Instance automatically?
I already successfully scheduled the compute Engine VM but stuck in SQL Instance scheduling.

In order to achieve this you can use a Cloud Function to make a call to the Cloud SQL Admin API to start and stop your Cloud SQL instance (you will need 2 Cloud functions)
def hello_world(request):
instance = 'test' # TODO: Update placeholder value.
request = service.instances().get(project=project, instance=instance)
response = request.execute()
j = response["settings"]
settingsVersion = int(j["settingsVersion"])
dbinstancebody = {
"settings": {
"settingsVersion": settingsVersion,
"tier": "db-n1-standard-1",
"activationPolicy": "Always"
}
}
request = service.instances().update(
project=project,
instance=instance,
body=dbinstancebody)
response = request.execute()
pprint(response)
request_json = request.get_json()
if request.args and 'message' in request.args:
return request.args.get('message')
elif request_json and 'message' in request_json:
return request_json['message']
else:
return f"Hello World!"

You can see my code on how to use a Cloud Function to start a Cloud SQL instance and stop a Cloud SQL instance
After creating your Cloud Function you can configure the Cloud Scheduler to trigger the HTTP address of each Cloud function or you can follow the recommended approach of this guide and trigger the functions with pub/sub
