This page describes how to start an instance, stop an instance, and restart an instance that is running.
Activation policy
When you start, stop, or restart an instance, you need to set an activation policy to use. The activation policy indicates if the instance is activated to accept connection requests.
Activation policy options are:
ALWAYS
- The instance is always up and running.NEVER
- The instance is not restarted.
ALWAYS
. If you
are not using your instance, you can set its activation policy to
NEVER
to avoid instance charges.
Start an instance
To start a stopped instance:
Console
-
In the Google Cloud console, go to the Cloud SQL Instances page.
- To open the Overview page of an instance, click the instance name.
- Click Start.
- In the Start database instance? dialog box, click
Start.
The activation policy of the instance is set to Always and the instance is started.
gcloud
Use ALWAYS for the activation policy:
gcloud sql instances patch INSTANCE_NAME \ --activation-policy=ALWAYS
REST v1
Before using any of the request data, make the following replacements:
- project-id: The project ID
- instance-id: The instance ID
- activation-policy: The activation policy is ALWAYS or NEVER
HTTP method and URL:
PATCH https://sqladmin.googleapis.com/v1/projects/project-id/instances/instance-id
Request JSON body:
{ "settings": { "activationPolicy": "activation-policy" } }
To send your request, expand one of these options:
You should receive a JSON response similar to the following:
{ "kind": "sql#operation", "targetLink": "https://sqladmin.googleapis.com/v1/projects/project-id/instances/instance-id", "status": "PENDING", "user": "user@example.com", "insertTime": "2020-01-20T21:30:35.667Z", "operationType": "UPDATE", "name": "operation-id", "targetId": "instance-id", "selfLink": "https://sqladmin.googleapis.com/v1/projects/project-id/operations/operation-id", "targetProject": "project-id" }
REST v1beta4
Before using any of the request data, make the following replacements:
- project-id: The project ID
- instance-id: The instance ID
- activation-policy: The activation policy is ALWAYS or NEVER
HTTP method and URL:
PATCH https://sqladmin.googleapis.com/sql/v1beta4/projects/project-id/instances/instance-id
Request JSON body:
{ "settings": { "activationPolicy": "activation-policy" } }

Stop an instance
You can manually stop an instance when needed. When you stop an instance, it remains stopped, and does not respond to application connections, until you start it again.
Stopping an instance suspends instance charges. The instance data is unaffected, and charges for storage and IP addresses continue to apply.
To stop an instance:
Console
-
In the Google Cloud console, go to the Cloud SQL Instances page.
- To open the Overview page of an instance, click the instance name.
- Click Stop.
- In the Stop database instance? dialog box, click
Stop.
The activation policy of the instance is set to
Off
(Never) and the instance is stopped.

Restart an instance
Restarting an instance drains the connections from the instance and stops it. Next, the instance restarts and is ready to accept new connections.
Restarting an instance doesn't change the public or private IP addresses of the instance.
To restart an instance:
Console
-
In the Google Cloud console, go to the Cloud SQL Instances page.
- To open the Overview page of an instance, click the instance name.
- Click Restart.
- In the Restart database instance? dialog box, click Restart.
gcloud
Restart the instance:
gcloud sql instances restart INSTANCE_NAME
