This page shows how to use Serverless VPC Access to connect your App Engine standard environment app directly to your VPC network, allowing access to Compute Engine VM instances, Memorystore instances, and any other resources with an internal IP address.
To use Serverless VPC Access, you must first create a Serverless VPC Access connector to handle communication to your VPC network. After you create a connector, you configure your App Engine services to use the connector.
Creating a Serverless VPC Access connector
For detailed instructions on creating Serverless VPC Access connectors, refer to Creating a connector.
Configuring your app to use a connector
After you have created a Serverless VPC Access connector, you can configure the services in your App Engine app to use the connector.
To specify a connector for a service in your app:
vpc_access_connectorsection to your service's
vpc_access_connector: name: projects/PROJECT_ID/locations/REGION/connectors/CONNECTOR_NAME
PROJECT_IDis your Cloud project ID,
REGIONis the region your connector is in, and
CONNECTOR_NAMEis the name of your connector.
Deploy the service:
gcloud app deploy
After you deploy your service, it is able to send requests to internal IP
addresses in order to access resources in your VPC network.
To disconnect a service from a VPC network, remove the
vpc_access_connector section from the
app.yaml file and re-deploy the service.
Connecting to a Shared VPC network
- Make sure an administrator of the host project completes the setup described at Using a Shared VPC network. This setup includes creating a Serverless VPC Access connector in the host project and attaching it to the Shared VPC network.
Enable the Serverless VPC Access API in your service project:
After the host project setup is complete, you can specify the host project's connector in your
app.yamlfile using the connector's fully-qualified name:
vpc_access_connector: name: projects/HOST_PROJECT_ID/locations/CONNECTOR_REGION/connectors/CONNECTOR_NAMEWhere
HOST_PROJECT_IDis the ID of the host project,
CONNECTOR_REGIONis the region the connector is in, and
CONNECTOR_NAMEis the name of the connector.
This connects your App Engine service to the Shared VPC network.
