Delete instances

MySQL   |  PostgreSQL   |  SQL Server

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:

• You cannot delete an instance that has any replicas. You must delete all replicas first.
  You can reduce your chances of accidentally deleting an instance by creating a replica; a replica must be deleted before its primary 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 a week 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.

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

Before attempting to delete an instance, confirm that it is safe to do so. Then confirm that deletion protection is disabled.

Console

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

   Go to Cloud SQL Instances

2. To open the Overview page of an instance, click the instance name.
3. Click Delete.
4. In the Delete database instance dialog box, click OK.

gcloud

Delete the instance.

gcloud sql instances delete INSTANCE_NAME

REST v1

Delete the instance.

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

• project-id: The project ID
• instance-id: The instance ID

HTTP method and URL:

DELETE https://sqladmin.googleapis.com/v1/projects/project-id/instances/instance-id

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-id"

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, 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:

$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-id" | 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/var>instance-id",
  "status": "PENDING",
  "user": "[e-mail]",
  "insertTime": "2020-01-15T00:10:22.078Z",
  "operationType": "DELETE",
  "name": "operation-id",
  "targetId": "instance-id",
  "selfLink": "https://sqladmin.googleapis.com/v1/projects/project-id/operations/operation-id",
  "targetProject": "project-id"
}
