MongoDB Atlas

This simple setup allows creating and configuring a managed MongoDB Atlas cluster, and connecting it to a local VPC network via Private Endpoints.

Prerequisites

The project.yaml file describes the project-level configuration needed in terms of API activation and IAM bindings.

If you are deploying this inside a FAST-enabled organization, the file can be lightly edited to match your configuration, and then used directly in the project factory.

This Terraform can of course be deployed using any pre-existing project. In that case use the YAML file to determine the configuration you need to set on the project:

• enable the APIs listed under services
• grant the permissions listed under iam to the principal running Terraform, either machine (service account) or human

Variable Configuration

Configuration is mostly done via the atlas_config and vpc_config variables. Note that:

• VPC configuration can be set to reference a Shared VPC Host network like shown below, or an in-project network if that is preferred
• the PSC CIDR block is used to allocate the required 50 endpoint addresses in the VPC, so it needs to be large enough to accommodate them
• the Atlas region must match the GCP subnetwork region

Bringing up a cluster and the associated connectivity from scratch will require approximately 30 minutes.
