# Cloud SQL for PostgreSQL Source
|
|
|
|
[Cloud SQL for PostgreSQL][csql-pg-docs] is a fully-managed database service
|
|
that helps you set up, maintain, manage, and administer your PostgreSQL
|
|
relational databases on Google Cloud Platform.
|
|
|
|
If you are new to Cloud SQL for PostgreSQL, you can try [creating and connecting
|
|
to a database by following these instructions][csql-pg-quickstart].
|
|

|
|
|
|
## Requirements
|
|
|
|
### IAM Identity
|
|
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:
|
|
- `roles/cloudsql.client`
|
|
|
|
[csql-go-conn]: https://github.com/GoogleCloudPlatform/cloud-sql-go-connector
|
|
[adc]: https://cloud.google.com/docs/authentication#adc
|
|
[set-adc]: https://cloud.google.com/docs/authentication/provide-credentials-adc
|
|
|
|
### Network Path
|
|
|
|
Currently, this source only supports [connecting over Public IP][public-ip].
|
|
Because it uses the Go connector, is uses rotating client certificates to
|
|
establish a secure mTLS connection with the instance.
|
|
|
|
[public-ip]: https://cloud.google.com/sql/docs/postgres/configure-ip
|
|
|
|
### Database User
|
|
|
|
Current, this source only uses standard authentication. You will need to [create a
|
|
PostreSQL user][cloud-sql-users] to login to the database with.
|
|
|
|
[cloud-sql-users]: https://cloud.google.com/sql/docs/postgres/create-manage-users
|
|
|
|
## Example
|
|
|
|
```yaml
|
|
sources:
|
|
my-cloud-sql-pg-source:
|
|
kind: "cloud-sql-pg-postgres"
|
|
project: "my-project"
|
|
region: "us-central1"
|
|
instance: "my-instance"
|
|
database: "my_db"
|
|
user: "my-user"
|
|
password: "my-password"
|
|
```
