    Configure public IP

    This page describes how to configure public IP connectivity for a Cloud SQL instance.

    Introduction

    You can configure your Cloud SQL instance to have a public IPv4 address, and to accept connections from specific IP addresses or a range of addresses by adding authorized addresses to your instance.

    You can't specify a private network (for example, 10.x.x.x) as an authorized network.

    Public IP addresses for MySQL instances:

    • IPv6: Instances don't support IPv6.
    • IPv4: Instances have a static IPv4 address automatically assigned. There is a small charge for the IP address any time your instance is off (deactivated).

    For help with connecting an administration client to your instance over an IP connection, see Connecting mysql Client using IP addresses .

    If you configure your instance to accept connections using its public IP address, also configure it to use SSL to keep your data secure. For more information, see Configure SSL for Instances .

    To configure your instance with an IP address that is not exposed to the public internet, see Configuring Private IP Connectivity .

    Enable public IP and add an authorized address or address range

    When you enable public IP for your instance, Cloud SQL configures the instance with a public, static IPv4 address. After you enable public IP, you must set up authorization for database connections. See the Authorization options for more information.

    If you're using either a shared certificate authority (CA) or a customer-managed CA as the serverCaMode for your instance, then your instance requires a restart when you enable public IP for your instance. For more information about server CA mode configuration, see Certificate authority (CA) authorities .

    To enable public IP and add an authorized address:

    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. From the SQL navigation menu, select Connections .
    4. Click the Networking tab.
    5. Select the Public IP checkbox.
    6. Click Add network .
    7. Optionally, in the Name field, enter a name for this network.
    8. In the Network field, enter the IP address or address range from which you want to allow connections.

      Use CIDR notation .

    9. Click Done .
    10. Click Save .

    gcloud

    1. If you haven't already, add an IPv4 address to the instance: 
      gcloud  
sql  
instances  
patch  
 INSTANCE_NAME 
 \ 
--assign-ip
    2. Show all existing authorized addresses by describing the instance: 
      gcloud  
sql  
instances  
describe  
 INSTANCE_NAME

      Look for authorizedNetwork entries under ipConfiguration , and note any authorized addresses you want to keep.

    3. Update the authorized network list, including all addresses you want included. 
      gcloud  
sql  
instances  
patch  
 INSTANCE_NAME 
  
 \ 
--authorized-networks = 
 IP_ADDR1 
, IP_ADDR2 
...

      Use CIDR notation .

    4. Confirm your changes: 
      gcloud  
sql  
instances  
describe  
 INSTANCE_NAME 


      
gcloud  
sql  
instances  
patch

    Terraform

    To enable public IP and add an authorized address or address range, use a Terraform resource .

     resource "google_sql_database_instance" "mysql_public_ip_instance_name" {
  database_version = "MYSQL_5_7"
  name             = "mysql-public-ip-instance-name"
  region           = "asia-southeast2"
  settings {
    availability_type = "ZONAL"
    disk_size         = 100
    disk_type         = "PD_SSD"
    ip_configuration {
      # Add optional authorized networks
      # Update to match the customer's networks
      authorized_networks {
        name  = "test-net-3"
        value = "203.0.113.0/24"
      }
      # Enable public IP
      ipv4_enabled = true
    }
    tier = "db-custom-4-26624"
  }
  # 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

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

      terraform destroy

      • AUTHORIZED_NETWORKS: For public IP connections, specify the connections from authorized networks that can connect to your instance.

      For the ipv4Enabled parameter, set the value to true if you're using a public IP address for your instance or false if your instance has a private IP address.

      If you set the enablePrivatePathForGoogleCloudServices parameter to true , then you allow other Google Cloud services, such as BigQuery, to access data in Cloud SQL and make queries against this data over a private IP connection. By setting this parameter to false , other Google Cloud services can't access data in Cloud SQL over a private IP connection.

      You can use the sqlNetworkArchitecture field to enforce the use of the new network architecture for the instance upon creation, even if the project isn't fully upgraded. For more details about the new network architecture and its implications, see Upgrade an instance to the new network architecture and Allocate an IP address range .

    Aborted connection .
    The issue might be:
    • Networking instability.
    • No response to TCP keep-alive commands (either the client or the server isn't responsive, possibly overloaded)
    • The database engine connection lifetime was exceeded and the server ends the connection.

    Applications must tolerate network failures and follow best practices such as connection pooling and retrying. Most connection poolers catch these errors where possible. Otherwise the application must either retry or fail gracefully.

    For connection retry, we recommend the following methods:

    1. Exponential backoff . Increase the time interval between each retry, exponentially.
    2. Add randomized backoff also.

    Combining these methods helps reduce throttling.

    Certificate verify failed .

    The client certificates have expired or the path to the certificates isn't correct.

    Regenerate the certificates by recreating them .
