Create and manage users

MySQL | PostgreSQL | SQL Server

This page describes how to enable and use Cloud SQL built-in authentication.

For additional information about users you create using Cloud SQL, see Other SQL Server users.

Before creating users

Create a Cloud SQL instance. For more information, see Create instances.
If you plan to use your database's administrative client to manage users, configure the default user on the instance by setting the password. See Set the password for the default user account.

Set the password for the default user account

When you create a new Cloud SQL instance, you must set a password for the default user account before you can connect to the instance.

For Cloud SQL for SQL Server, the default user is sqlserver.

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.
Select Users from the SQL navigation menu.
Find the sqlserver user and select Change password from the more actions menu .
Provide a strong password that you can remember and click OK.

gcloud

Use the gcloud sql users set-password command as follows to set the password for the default user.

Replace INSTANCE_NAME with the name of the instance before running the command.

gcloud sql users set-password sqlserver \
--instance=INSTANCE_NAME \
--prompt-for-password

REST v1

To update the password for the default user account, use a PUT request with the users:update method.

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

project-id: Your project ID
instance-id: The desired instance ID
user-id: The ID of the user
password: The password for the user

HTTP method and URL:

PUT https://sqladmin.googleapis.com/v1/projects/project-id/instances/instance-id/users?name=user-id

Request JSON body:

{
  "name": "user-id",
  "password": "password"
}

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.

Save the request body in a file named request.json, and execute the following command:

curl -X PUT \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://sqladmin.googleapis.com/v1/projects/project-id/instances/instance-id/users?name=user-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 . You can check the currently active account by running gcloud auth list.

Save the request body in a file named request.json, and execute the following command:

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

}

Create a user

After setting up the default user account, you can create other users.

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.
Select Users from the SQL navigation menu.
Click Add user account.
In the Add a user account to instance instance_name page, add the following information:
- A Username.
- A Password (optional).
Click Add.

gcloud

To create a user, use the gcloud sql users create command.

Replace the following:

USER_NAME: The user name.
INSTANCE_NAME: The name of the instance.
PASSWORD: The password for the user.

gcloud sql users create USER_NAME \
--instance=INSTANCE_NAME \
--password=PASSWORD

User name length limits are the same for Cloud SQL as for on-premises SQL Server.

Terraform

To create a user, use a Terraform resource.

resource "random_password" "pwd" {
  length  = 16
  special = false
}

resource "google_sql_user" "user" {
  name     = "user"
  instance = google_sql_database_instance.instance.name
  password = random_password.pwd.result
}

Apply the changes

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

Prepare Cloud Shell

Launch Cloud Shell.
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).

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
```
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.
Review and modify the sample parameters to apply to your environment.
Save your changes.
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

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.
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.
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:

To disable deletion protection, in your Terraform configuration file set the deletion_protection argument to false.
```
deletion_protection =  "false"
```
Apply the updated Terraform configuration by running the following command and entering yes at the prompt:
```
terraform apply
```

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

REST v1
