This page has procedures for creating or editing Cloud SQL instances to
allow users, service accounts, or groups that are configured to use Cloud SQL
IAM database authentication. To learn more about the Cloud SQL IAM
integration, see [IAM authentication](https://docs.cloud.google.com/sql/docs/postgres/iam-authentication.md.txt).


A newly-created instance has a `postgres` database.

<br />

## Before you begin

1. Make sure you have the Cloud SQL Admin and Compute Viewer roles on your user account. [Go to the IAM page](https://console.cloud.google.com/iam-admin/iam)

   [Learn more](https://docs.cloud.google.com/sql/docs/postgres/roles-and-permissions.md.txt)
   about roles and permissions.

The maximum number of instances you can have in a single project depends on the
[network
architecture](https://docs.cloud.google.com/sql/docs/postgres/upgrade-cloud-sql-instance-new-network-architecture#overview)
of those instances:

- New SQL network architecture: You can have up to 1,000 instances per project.
- Old SQL network architecture: You can have up to 100 instances per project.
- Using both architectures: Your limit will be somewhere between 100 and 1,000, depending on the distribution of your instances across the two architectures.

[File a support case](https://support.google.com/googlecloud/answer/1041916)
to request an increase. Read replicas are counted as instances.

## Configure new instances for IAM database authentication

To configure a new Cloud SQL instance for IAM database authentication,
you need to enable the `cloudsql.iam_authentication`
flag.
After you enable this flag, you can add IAM users, service
accounts, or groups to the Cloud SQL instance.

To configure a new Cloud SQL instance to use IAM database authentication:

### Console

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

   [Go to Cloud SQL Instances](https://console.cloud.google.com/sql)
2. Click **Create Instance**.
3. Click **Choose PostgreSQL**.
4. Enter a name for the **Instance ID**.
Don't include sensitive or personally identifiable information in your instance name; it's externally visible. You don't need to include the project ID in the instance name. The project ID is included automatically where appropriate (for example, in the log files).
5. Enter a password for the default administrator.
6. From the **Database version** menu, select a database version.
7. In the **Choose region and zonal availability** section, select the region and zone for your instance. Place your instance in the same region as the resources that access it. The region you select can't be modified in the future. Usually, you don't need to specify a zone.

   > [!NOTE]
   > **Note:** If there's a resource location constraint on your organization policy, then you must select one of the regions that the organization policy allows. If a constraint exists, then a message appears about the constraint. [Learn more](https://docs.cloud.google.com/resource-manager/docs/organization-policy/defining-locations).

8. In the **Customize your instance** section, click **Show Configuration Options** , and then expand **Flags**.
9. Click **Add Flag**.
10. From the **Choose a flag** menu, select the `cloudsql.iam_authentication` flag. Make sure that **On** is selected as the value for this flag, and then click **Done**.
11. Configure other instance settings, as needed. For more information about settings, see [Settings](https://docs.cloud.google.com/sql/docs/postgres/instance-settings.md.txt#settings-2ndgen).
12. Click **Create Instance**.

### gcloud

Run
`gcloud sql instances create`
with the `--database-flags` parameter set to
`cloudsql.iam_authentication=on`.

Replace the following:

- <var translate="no">INSTANCE_NAME</var>: the name of the new instance.
- <var translate="no">POSTGRES_VERSION</var>: the PostgreSQL version (such as POSTGRES_9_6, POSTGRES_10, POSTGRES_11, or POSTGRES_12).
- <var translate="no">NUMBER_OF_CORES</var>: the number of cores in the machine.
- <var translate="no">AMOUNT_OF_MEMORY</var>: the amount of memory in the machine. A size unit should be provided (such as, 3072MiB or 9GiB).
- <var translate="no">ZONE</var>: preferred Compute Engine zone (such as us-central1-a, or us-central1-b).
- <var translate="no">PASSWORD</var>: create a password for the root user.

```bash
gcloud sql instances create INSTANCE_NAME \
--database-version=POSTGRES_VERSION \
--cpu=NUMBER_OF_CORES \
--memory=AMOUNT_OF_MEMORY \
--zone=ZONE_NAME \
--root-password=PASSWORD \
--database-flags=cloudsql.iam_authentication=on
```

### Terraform

To create an instance with IAM database authentication enabled,
use a [Terraform resource](https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/sql_database_instance).

```terraform
resource "google_sql_database_instance" "default" {
  name             = "postgres-db-auth-instance-name-test"
  region           = "us-west4"
  database_version = "POSTGRES_14"
  settings {
    tier = "db-custom-2-7680"
    database_flags {
      name  = "cloudsql.iam_authentication"
      value = "on"
    }
  }
}
```

#### Apply the changes

To apply your Terraform configuration in a Google Cloud project, complete the steps in the
following sections.

## Prepare Cloud Shell

1. Launch [Cloud Shell](https://shell.cloud.google.com/).
2. Set the default Google Cloud project
   where you want to apply your Terraform configurations.

   You only need to run this command once per project, and you can run it in any directory.

   ```
   export GOOGLE_CLOUD_PROJECT=PROJECT_ID
   ```

   Environment variables are overridden if you set explicit values in the Terraform
   configuration file.

## Prepare the directory

Each Terraform configuration file must have its own directory (also
called a *root module*).

1. In [Cloud Shell](https://shell.cloud.google.com/), create a directory and a new file within that directory. The filename must have the `.tf` extension---for example `main.tf`. In this tutorial, the file is referred to as `main.tf`.

   ```
   mkdir DIRECTORY && cd DIRECTORY && touch main.tf
   ```
2. If you are following a tutorial, you can copy the sample code in each section or step.

   Copy the sample code into the newly created `main.tf`.

   Optionally, copy the code from GitHub. This is recommended
   when the Terraform snippet is part of an end-to-end solution.
3. Review and modify the sample parameters to apply to your environment.
4. Save your changes.
5. Initialize Terraform. You only need to do this once per directory.

   ```
   terraform init
   ```

   Optionally, to use the latest Google provider version, include the `-upgrade`
   option:

   ```
   terraform init -upgrade
   ```

## Apply the changes

1. Review the configuration and verify that the resources that Terraform is going to create or update match your expectations:

   ```
   terraform plan
   ```

   Make corrections to the configuration as necessary.
2. Apply the Terraform configuration by running the following command and entering `yes` at the prompt:

   ```
   terraform apply
   ```

   Wait until Terraform displays the "Apply complete!" message.
3. [Open your Google Cloud project](https://console.cloud.google.com/) to view the results. In the Google Cloud console, navigate to your resources in the UI to make sure that Terraform has created or updated them.

> [!NOTE]
> **Note:** Terraform samples typically assume that the required APIs are enabled in your Google Cloud project.

#### Delete the changes

To delete your changes, do the following:

1. To disable deletion protection, in your Terraform configuration file set the `deletion_protection` argument to `false`.

   ```
   deletion_protection =  "false"
   ```
2. Apply the updated Terraform configuration by running the following command and entering `yes` at the prompt:

   ```
   terraform apply
   ```

<!-- -->

3. Remove resources previously applied with your Terraform configuration by running the following
   command and entering `yes` at the prompt:

   ```
   terraform destroy
   ```

### REST v1

## Configure existing instances for IAM database authentication

To configure an existing Cloud SQL instance for IAM database authentication, you need to
enable the `cloudsql.iam_authentication`
flag.
After you enable this flag, you can add IAM users, service
accounts, or groups to the Cloud SQL instance.

To configure an existing Cloud SQL instance to use IAM database authentication:

### Console

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

   [Go to Cloud SQL Instances](https://console.cloud.google.com/sql)
2. To open the **Overview** page of an instance, click the instance name.
3. Click **Edit**.
4. In the **Customize your instance** section, expand **Flags**.
5. Click **Add Flag**.
6. From the **Choose a flag** menu, select the `cloudsql.iam_authentication` flag. Make sure that **On** is selected as the value for this flag, and then click **Done**.
7. Configure other instance settings, as needed. For more information about settings, see [Settings](https://docs.cloud.google.com/sql/docs/postgres/instance-settings.md.txt#settings-2ndgen).
8. Click **Save**.

### gcloud

For information about installing and getting started with the
gcloud CLI, see [Install the
gcloud CLI](https://docs.cloud.google.com/sdk/docs/install). For information about starting Cloud Shell, see
[Use Cloud Shell](https://docs.cloud.google.com/shell/docs/using-cloud-shell.md.txt).

For this procedure, use
`
gcloud
sql instances patch`.

Replace the following:

- <var translate="no">INSTANCE_NAME</var>: the name of the new instance.

```bash
gcloud sql instances patch INSTANCE_NAME \
--database-flags=cloudsql.iam_authentication=on
```

This resets all other existing database flag settings. For further guidance on setting database flags, see
[Set a database flag](https://docs.cloud.google.com/sql/docs/postgres/flags.md.txt#set_a_database_flag).
