About

Cloud SQL for MySQL is a fully-managed database service that helps you set up, maintain, manage, and administer your MySQL relational databases on Google Cloud Platform.

If you are new to Cloud SQL for MySQL, you can try creating and connecting to a database by following these instructions.

Available Tools

• mysql-sql
  Execute pre-defined prepared SQL queries in MySQL.

• mysql-execute-sql
  Run parameterized SQL queries in Cloud SQL for MySQL.

Pre-built Configurations

• Cloud SQL for MySQL using MCP
  Connect your IDE to Cloud SQL for MySQL using Toolbox.

Requirements

IAM Permissions

By default, this source uses the Cloud SQL Go Connector to authorize and establish mTLS connections to your Cloud SQL instance. The Go connector uses your Application Default Credentials (ADC) to authorize your connection to Cloud SQL.

In addition to setting the ADC for your server, you need to ensure the IAM identity has been given the following IAM roles (or corresponding permissions):

• roles/cloudsql.client

{{< notice tip >}} If you are connecting from Compute Engine, make sure your VM also has the proper scope to connect using the Cloud SQL Admin API. {{< /notice >}}

Networking

Cloud SQL supports connecting over both from external networks via the internet (public IP), and internal networks (private IP). For more information on choosing between the two options, see the Cloud SQL page Connection overview.

You can configure the ipType parameter in your source configuration to public or private to match your cluster's configuration. Regardless of which you choose, all connections use IAM-based authorization and are encrypted with mTLS.

Database User

Currently, this source only uses standard authentication. You will need to create a MySQL user to login to the database with.

Example

sources:
    my-cloud-sql-mysql-source:
        kind: cloud-sql-mysql
        project: my-project-id
        region: us-central1
        instance: my-instance
        database: my_db
        user: ${USER_NAME}
        password: ${PASSWORD}
        # ipType: "private"

{{< notice tip >}} Use environment variable replacement with the format ${ENV_NAME} instead of hardcoding your secrets into the configuration file. {{< /notice >}}
