Create instances

Console

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

   Go to Cloud SQL Instances

2. Click Create instance.
3. On the Choose your database engine panel of the Create an instance page, click Choose SQL Server.

4. In the Choose a Cloud SQL edition section of the Create a SQL Server instance page, select the Cloud SQL edition for your instance: Enterprise or Enterprise plus.

   For more information about Cloud SQL editions, see Introduction to Cloud SQL editions.

5. Select the edition preset for your instance. To see the available presets, click the Edition preset menu.
6. In the Instance info section, select the database version for your instance. To see the available versions, click the Database version menu.
7. In the Instance ID field of the Instance info pane, enter an ID for your instance.
   

   You do not need to include the project ID in the instance name. This is done automatically where appropriate (for example, in the log files).

8. In the Password field, enter a password for the user.

To see the password in clear text, click the Show password icon.

You can either enter the password manually or click Generate to have Cloud SQL create a password for you automatically.

9. In the Choose region and zonal availability section, select the region and zone for your instance. Region availability might be different based on your Cloud SQL for SQL Server edition. For more information, see About instance settings.

   Place your instance in the same region as the resources that access it. The region you select can't be modified in the future. In most cases, you don't need to specify a zone.

   If you are configuring your instance for high availability, you can select both a primary and secondary zone.

   The following conditions apply when the secondary zone is used during instance creation:

   • The zones default to Any for the primary zone and Any (different from primary) for the secondary zone.
   • If both the primary and secondary zones are specified, they must be distinct zones.
10. In the Customize your instance section, update settings for your instance. Begin by clicking SHOW CONFIGURATION OPTIONS to display the groups of settings. Then, expand the groups you want to review and customize settings. A Summary of all the options you select is shown on the right. Customizing these instance settings is optional. Defaults are assigned in every case where no customizations are made.

    The following table is a quick reference to instance settings. For more details about each setting, see the instance settings page.

11. Click Create Instance.

    Note: It might take a few minutes to create your instance. However, you can view information about the instance while it's being created.

gcloud

For information about installing and getting started with the gcloud CLI, see Installing gcloud CLI. For information about starting Cloud Shell, see the Cloud Shell documentation.

You must use gcloud version 243.0.0 or later.

1. Use the gcloud sql instances create command to create the instance:

For Cloud SQL Enterprise Plus edition instances:

      gcloud sql instances create INSTANCE_NAME \
      --database-version=DATABASE_VERSION \
      --region=REGION \
      --tier=TIER \
      --root-password=ROOT_PASSWORD \
      --edition=ENTERPRISE_PLUS
    

For Cloud SQL Enterprise edition instances:

      gcloud sql instances create INSTANCE_NAME \
      --database-version=DATABASE_VERSION \
      --region=REGION \
      --cpu=NUMBER_OF_vCPUs \
      --memory=MEMORY_SIZE \
      --root-password=ROOT_PASSWORD \
      --edition=ENTERPRISE
    

You do not need to include the project ID in the instance name. This is done automatically where appropriate (for example, in the log files).

The values for vCPUs and memory size are limited for Cloud SQL Enterprise edition. For more information, see Choose between Cloud SQL Enterprise Plus edition and Cloud SQL Enterprise edition.

For example, the following string creates an instance with two vCPUs and 7,680 MB of memory:

    gcloud sql instances create myinstance \
    --database-version=SQLSERVER_2017_STANDARD \
    --region=us-central1 \
    --cpu=2 \
    --memory=7680MB \
    --root-password=EXAMPLE_PASSWORD \
    --edition=ENTERPRISE
    

For some sample values, see Sample machine types.

To learn about the parameters for instance settings, see gcloud sql instances create.

The default value for REGION is us-central1.

Don't include sensitive or personally identifiable information in your instance name; it is externally visible.
You do not need to include the project ID in the instance name. This is done automatically where appropriate (for example, in the log files).

If you are creating an instance for high availability, you can specify both the primary and secondary zones, using the --zone and --secondary-zone parameters. The following conditions apply when the secondary zone is used during instance creation or edit:

• The zones must be valid zones.
• If the secondary zone is specified, the primary must also be specified.
• If the primary and secondary zones are specified, they must be distinct zones.
• If the primary and secondary zones are specified, they must belong to the same region.

You can add more parameters to determine other instance settings:

Setting	Parameter	Notes
Required parameters
Database version	--database-version	The database version, which is based on your Cloud SQL edition.
Region	--region	See valid values.
Connectivity
Private IP	--network --no-assign-ip (optional) --allocated-ip-range-name (optional) --enable-google-private-path (optional)	--network: Specifies the name of the VPC network you want to use for this instance. Private services access must already be configured for the network. Available only for the beta command (gcloud beta sql instances create). --no-assign-ip: Instance will only have a private IP address. --allocated-ip-range-name: If specified, sets a range name for which an IP range is allocated. For example, google-managed-services-default. The range name should comply with RFC-1035 and be within 1-63 characters. (gcloud alpha sql instances create).
Public IP	--authorized-networks	For public IP connections, only connections from authorized networks can connect to your instance. Learn more.
Server CA mode	--server-ca-mode	The --server-ca-mode flag configures the type of server certificate authority (CA) for an instance. You can select one of the following options: GOOGLE_MANAGED_INTERNAL_CA: this is the default value. With this option, an internal CA dedicated to each Cloud SQL instance signs the server certificate for that instance. GOOGLE_MANAGED_CAS_CA: with this option, a CA hierarchy consisting of a root CA and subordinate server CAs managed by Cloud SQL and hosted on Google Cloud Certificate Authority Service (CA Service) is used. The subordinate server CAs in a region sign the server certificates and are shared across instances in the region. Using the --server-ca-mode flag is in Preview. This option is in Preview. CUSTOMER_MANAGED_CAS_CA: with this option, you define the CA hierarchy and manage the rotation of the CA certificates. You create a CA pool in CA Service in the same region of your instance. One of the CAs in the pool is used to sign the server certificate. This option is in Preview. For more information, see Use a customer-managed CA.
Machine type and storage
Machine type	--tier
Storage type	--storage-type	Determines whether your instance uses SSD or HDD storage. Learn more.
Storage capacity	--storage-size	The amount of storage provisioned for the instance, in GB. Learn more.
Automatic storage increase	--storage-auto-increase	Determines whether Cloud SQL automatically provides more storage for your instance when free space runs low. Learn more.

Automatic backups and high availability
High availability	--availability-type	For a highly-available instance, set to REGIONAL. Learn more.
Secondary zone	--secondary-zone	If you're creating an instance for high availability, you can specify both the primary and secondary zones using the --zone and --secondary-zone parameters. The following restrictions apply when the secondary zone is used during instance creation or edit: The zones must be valid zones. If the secondary zone is specified, the primary must also be specified. If the primary and secondary zones are specified, they must be distinct zones. If the primary and secondary zones are specified, they must belong to the same region.
Automatic backups	--backup-start-time	The window of time when you would like backups to start.
Retention settings for automated backups	--retained-backups-count	The number of automated backups to retain. Learn more.
Retention settings for transaction logs	--retained-transaction-log-days	The number of days to retain transaction logs for point-in-time recovery. Learn more.
Point-in-time recovery	--enable-point-in-time recovery	Enables point-in-time recovery and transaction logs. Learn more.
Add database flags
Database flags	--database-flags	You can use database flags to control settings and parameters for your instance. Learn more about database flags.
Maintenance schedule
Maintenance window	--maintenance-window-day, --maintenance-window-hour	Determines a one-hour window when Cloud SQL can perform disruptive maintenance on your instance. If you don't set the window, then disruptive maintenance can be done at any time. Learn more.
Maintenance timing	--maintenance-release-channel	Your preferred timing for instance updates, relative to other instances in the same project. Use preview for earlier updates, and production for later updates. Learn more.
Custom SAN
Add a custom subject alternative name (SAN)	--custom-subject-alternative-names=DNS_NAMES	If you want to use a custom DNS name to connect to a Cloud SQL instance instead of using an IP address, then configure the custom subject alternative name (SAN) setting while creating the instance. The custom DNS name that you insert into the custom SAN setting is added to the SAN field of the server certificate of the instance. This lets you use the custom DNS name with hostname validation securely. Before you can use the custom DNS name in your clients and applications, you must set up the mapping between the DNS name and the IP address. This is known as DNS resolution. You can add a comma-separated list of up to three custom DNS names to the custom SAN setting.

2. Note the automatically assigned IP address.

   If you are not using the Cloud SQL Auth Proxy, you will use this address as the host address that your applications or tools use to connect to the instance.

3. Set the password for the user:

         gcloud sql users set-password sqlserver no-host --instance=[INSTANCE_NAME] \
          --password=[PASSWORD]
         

Terraform

To create an instance, use a Terraform resource.

resource "google_sql_database_instance" "instance" {
  name             = "sqlserver-instance"
  region           = "us-central1"
  database_version = "SQLSERVER_2019_STANDARD"
  root_password    = "INSERT-PASSWORD-HERE"
  settings {
    tier = "db-custom-2-7680"
  }
  # set `deletion_protection` to true, will ensure that one cannot accidentally delete this instance by
  # use of Terraform whereas `deletion_protection_enabled` flag protects this instance at the GCP level.
  deletion_protection = false
}

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.

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, 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 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.

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

1. Create the instance

Not all possible fields are shown in the following basic API call. For a prototype of a JSON request, see Settings.

Also see the Instances:insert page. For information about instance settings, including valid values for regions, see Instance settings. For information about machine types, see Custom instance configurations.

Don't include sensitive or personally identifiable information in instance-id; the value is externally visible.

You do not need to include the project ID in the instance name. This is done automatically where appropriate (for example, in the log files).

The collation field (not shown in the following basic API call) lets you set a default value for the type of collation used for the databases in your instance. This collation default is permanent at the instance level but not at the database level. You can change this default with a database administration tool, but only for a specific database that you are creating or updating. You cannot change the collation default for an instance after creating the instance (unless you recreate the instance). For information about collations in SQL Server, see Collation and Unicode support. For a prototype of a JSON request, see Settings. You can specify the following example string for the collation parameter: SQL_Latin1_General_CP1_CI_AS.

The timeZone field (not shown in the following basic API call) lets you to set a time zone for an instance. After you create an instance, you can change the time zone of an instance. For more information and a list of accepted strings, see Settings. You can specify the following example string for the timeZone field: "Pacific Standard Time". See more.

To create an instance that is integrated with Managed Microsoft AD, specify a domain, such as subdomain.mydomain.com, for the domain field. For more information, see Creating an instance with Windows Authentication. Additionally, note the procedures and constraints for integrating with a Managed Microsoft AD domain in a different project.

}

After the instance is created, you can further configure the default user account.

2. Retrieve the IPv4 address of the instance

Optionally, you can retrieve the automatically-assigned IPv4 address. In the response, that address is in the ipAddress field.

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

• PROJECT_ID: your project ID
• INSTANCE_ID: your instance ID, created in the previous step

HTTP method and URL:

GET https://sqladmin.googleapis.com/sql/v1beta4/projects/PROJECT_ID/instances/INSTANCE_ID

To send your request, expand one of these options:

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://sqladmin.googleapis.com/sql/v1beta4/projects/PROJECT_ID/instances/INSTANCE_ID"

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

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://sqladmin.googleapis.com/sql/v1beta4/projects/PROJECT_ID/instances/INSTANCE_ID" | Select-Object -Expand Content

You should receive a JSON response similar to the following:
