Create a New Network Peering Container

Creates one Network Peering container into which Atlas can deploy Network Peering connections.

The following table outlines the maximum number of Network Peering containers per cloud provider:

Cloud ProviderContainer Limit
GCPOne container per project.
AWS and AzureOne container per cloud provider region.

You must have either the Project Owner or Organization Owner role to successfully call this endpoint.

Info With Circle IconCreated with Sketch.Note

Groups and projects are synonymous terms. Your {GROUP-ID} is the same as your project ID. For existing groups, your group/project ID remains the same. The resource and corresponding endpoints use the term groups.

Base URL:

POST /groups/{GROUP-ID}/containers
GROUP-IDstringRequiredUnique identifier for the Atlas project whose Network Peering container details you want to retrieve.

This endpoint might use any of the HTTP request query parameters available to all Atlas API resources. All of these are optional.

prettybooleanOptionalFlag indicating whether the response body should be in a prettyprint format.false

Flag indicating if Atlas should wrap the response in a JSON envelope.

This option may be needed for some API clients. These clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query.

For endpoints that return one result, the response body includes:

statusHTTP response code
envelopeExpected response body

CIDR block that Atlas uses for the network peering containers in your project.

Atlas uses the specified CIDR block for all other Network Peering connections created in the project. The Atlas CIDR block must be at least a /24 and at most a /21 in one of the following private networks.

Lower BoundUpper BoundPrefix

Atlas locks this value if an M10+ cluster or a Network Peering connection already exists. To modify the CIDR block, ensure there are no M10+ clusters in the project and no other VPC peering connections in the project.

Alternatively, create a new project and create a Network Peering Connection to set the desired Atlas VPC CIDR block for that project.

Important With Circle IconCreated with Sketch.Important

Atlas limits the number of MongoDB nodes per Network Peering connection based on the CIDR block and the region selected for the project.

Beaker IconExample

A project in an AWS region supporting 3 availability zones and a Atlas CIDR VPC block of /24 is limited to the equivalent of 27 three-node replica sets.
