This page describes how to delete Cloud SQL instances.

Warning: All data on an instance, including backups, is permanently lost when that instance is deleted. To preserve your data, export it to Cloud Storage before you delete it. The Cloud SQL Admin role includes the permission to delete the instance. To prevent accidental deletion, grant this role only as needed. Additionally, consider deletion protection.

Note the following when you plan to delete an instance:

After you delete an instance, it might continue to appear in your project with an "unknown" size but with a "Being deleted" status. This is normal and the instance disappears completely after a brief period of time.
It can take up to four days for the underlying resources related to an instance to be completely deleted, with the exception of read replicas, which are often deleted within a few minutes.
The deleted instance name can be reused immediately to create a new instance.
If deletion protection is enabled on an instance, you must disable it before deleting the instance.
In case of contingencies, take a final backup to restore the deleted instance.

Required permissions

By default, only user or service accounts with the Cloud SQL Admin (roles/cloudsql.admin) or Owner (roles/owner) role have the permission to delete a Cloud SQL instance (cloudsql.instances.delete).

You can also define an IAM custom role for the user or service account that includes the cloudsql.instances.delete permission. This permission is supported in IAM custom roles.

Delete an instance

You can delete a Cloud SQL instance by using the Google Cloud console, gcloud CLI, or the API. If you want to retain backups for your instance prior to deleting, see Manage retained backups.

Note: Before you delete an instance, confirm that it's safe to do so. Then, confirm that deletion protection is deactivated for the instance. Also, we strongly recommend that you take a final backup of the instance before you delete it.

If you used Cloud Key Management Service to encrypt your instance, but the KMS keys aren't accessible, then after you delete the instance, the status of the final backup is FAILED. If this occurs, then request to recover your instance by contacting Cloud Customer Care within 4 days from the time that you deleted the instance.

If you delete an instance that has Private Service Connect enabled for it, then the following actions occur:

The service attachment is removed automatically. However, the Private Service Connect endpoint that points to the service attachment isn't deleted automatically. By listing the forwarding rule that's associated with the endpoint, you can see that the rule has a CLOSED status. After you receive this status, you can delete the endpoint.
You see the connection to the endpoint time out.

To avoid incurring additional costs, we strongly recommend that you also delete the corresponding DNS zone and DNS record.

Console

In the Google Cloud console, go to the Cloud SQL Instances page.

Go to Cloud SQL Instances
To open the Overview page of an instance, click the instance name.
Click Delete.
In the Delete instance dialog, complete the following actions:

In the text field, enter the instance ID that appears.
If you want to take a final backup of the instance, leave the Take a final backup checkbox selected, expand the Retention options menu, and then, in the Retain for field, enter the number of days to retain the final backup. You can specify from 1 to 365 days.

If you want to delete the instance without taking a final backup, then clear the checkbox.
In the Describe this backup text area, you can provide a description of the backup.
Click Delete.

gcloud

To delete an instance, use the gcloud sql instances delete command:

gcloud sql instances delete INSTANCE_NAME \
--project=PROJECT_ID

Make the following replacements:

INSTANCE_NAME: the name of the instance
PROJECT_ID: the ID or project number of the Google Cloud project that contains the instance that you want to delete

Note: If you want to take a final backup of the instance, then use the following flags:

--enable-final-backup: set the value of this flag to true to take a final backup. If you want to delete the instance without taking a final backup, then set the value to false.
--final-backup-description: provide details about the final backup. The default value is empty.
--final-backup-ttl-days: specify the number of days to retain the final backup. This is known as time to live (TTL). The default value is 30 days. The allowed retention period varies, from 1 to 365 days. To provide the retention period, use either this flag or --final-backup-expiry-time.
--final-backup-expiry-time: this is a timestamp (in UTC) of when the backup is set to expire. This can't exceed 1 year. To provide the retention period, use either this flag or --final-backup-ttl-days.

REST v1

Before using any of the request data, make the following replacements:

PROJECT_ID: the ID or project number of the Google Cloud project that contains the instance that you want to delete
INSTANCE_NAME: the name of the instance

Note: If you want to take a final backup of the instance, then use the following query parameters:

enable_final_backup: set the value of this parameter to true to take a final backup. If you want to delete the instance without taking a final backup, then set the value to false.
final_backup_description: provide details about the final backup. The default value is empty.
final_backup_ttl_days: specify the number of days to retain the final backup. This is known as time to live (TTL). The default value is 30 days. The allowed retention period varies, from 1 to 365 days. To provide the retention period, use either this parameter or final_backup_expiry_time.
final_backup_expiry_time: this is a timestamp (in UTC) of when the backup is set to expire. This can't exceed 1 year. To provide the retention period, use either this parameter or final_backup_ttl_days.

HTTP method and URL:

DELETE https://sqladmin.googleapis.com/v1/projects/PROJECT_ID/instances/INSTANCE_NAME

To send your request, expand one of these options:

curl (Linux, macOS, or Cloud Shell)

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login , or by using Cloud Shell, which automatically logs you into the gcloud CLI . You can check the currently active account by running gcloud auth list.

Execute the following command:

curl -X DELETE \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://sqladmin.googleapis.com/v1/projects/PROJECT_ID/instances/INSTANCE_NAME"

PowerShell (Windows)

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login . You can check the currently active account by running gcloud auth list.

Execute the following command:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method DELETE `
    -Headers $headers `
    -Uri "https://sqladmin.googleapis.com/v1/projects/PROJECT_ID/instances/INSTANCE_NAME" | Select-Object -Expand Content

You should receive a JSON response similar to the following:

{
  "kind": "sql#operation",
  "targetLink": "https://sqladmin.googleapis.com/v1/projects/PROJECT_ID/instances/INSTANCE_NAME",
  "status": "PENDING",

  "targetId": "INSTANCE_NAME",
  "selfLink": "https://sqladmin.googleapis.com/v1/projects/PROJECT_ID/operations/OPERATION_ID",
  "targetProject": "PROJECT_ID"
}

Restore a deleted instance

When you delete an instance, Cloud SQL deletes all resources for the instance, including on-demand backups and automated backups.

If you take a final backup as part of deleting an instance, then you can use this backup to recover the instance, either by creating an instance from the final backup or by restoring the final backup to an existing instance.

If you use a final backup to recover your instance, then your instance might have a different IP address from the original, deleted instance.

If you delete an instance accidentally without taking a final backup, then you can request to recover the instance by contacting Cloud Customer Care within 4 days from the time that the instance is deleted. If the instance can be recovered, then the instance configuration, including IP addresses used before the deletion, are restored. All backups available at the time of deletion are also recovered.
