## About
|
|
|
|
[Cloud SQL for MySQL][csql-mysql-docs] is a fully-managed database service

|
|
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][csql-mysql-quickstart].

### Pre-built Configurations
|
|
|
|
- [Cloud SQL for MySQL using
|
|
MCP](https://googleapis.github.io/genai-toolbox/how-to/connect-ide/cloud_sql_mysql_mcp/)
|
|
Connect your IDE to Cloud SQL for MySQL using Toolbox.
|
|
|
|
## Requirements
|
|
|
|
### IAM Permissions
|
|
|
|
By default, this source uses the [Cloud SQL Go Connector][csql-go-conn] to
|
|
authorize and establish mTLS connections to your Cloud SQL instance. The Go
|
|
connector uses your [Application Default Credentials (ADC)][adc] to authorize
|
|
your connection to Cloud SQL.
|
|
|
|
In addition to [setting the ADC for your server][set-adc], 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](https://cloud.google.com/compute/docs/access/service-accounts#accesscopesiam)
|
|
to connect using the Cloud SQL Admin API.

|
|
[set-adc]: https://cloud.google.com/docs/authentication/provide-credentials-adc
|
|
|
|
### Networking
|
|
|
|
Cloud SQL supports connecting over both from external networks via the internet
|
|
([public IP][public-ip]), and internal networks ([private IP][private-ip]).
|
|
For more information on choosing between the two options, see the Cloud SQL page
|
|
[Connection overview][conn-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.

|
|
|
|
### Authentication
|
|
|
|
This source supports both password-based authentication and IAM
|
|
authentication (using your [Application Default Credentials][adc]).
|
|
|
|
#### Standard Authentication
|
|
|
|
To connect using user/password, [create
|
|
a MySQL user][cloud-sql-users] and input your credentials in the `user` and
|
|
`password` fields.
|
|
|
|
```yaml
|
|
user: ${USER_NAME}
|
|
password: ${PASSWORD}
|
|
```
|
|
|
|
[cloud-sql-users]: https://cloud.google.com/sql/docs/mysql/create-manage-users
|
|
|
|
#### IAM Authentication
|
|
|
|
To connect using IAM authentication:
|
|
|
|
1. Prepare your database instance and user following this [guide][iam-guide].
|
|
2. You could choose one of the two ways to log in:
|
|
- Specify your IAM email as the `user`.
|
|
- Leave your `user` field blank. Toolbox will fetch the [ADC][adc]
|
|
automatically and log in using the email associated with it.
|
|
|
|
3. Leave the `password` field blank.

## Example
|
|
|
|
```yaml
|
|
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.
