Create One New Container

On this page

Creates one cloud provider container with a VPC into which Atlas can deploy clusters. An Atlas project can have a maximum of one AWS container per AWS region and one GCP container.

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.

POST /groups/{GROUP-ID}/containers

Request Path Parameters

Parameter Type Necessity Description
GROUP-ID string Required Unique identifier for the project whose container you want to retrieve.

Request Query Parameters

This endpoint may use any of the HTTP request query parameters available to all Atlas API resources. These are all optional.

Name Type Description Default
pretty boolean Indicates whether the response body should be in a prettyprint format. false
envelope boolean

Indicates whether or not to wrap the response in an envelope.

Some API 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:

status HTTP response code
envelope The expected response body
false

Request Body Parameters

Parameter Type Necessity Description
atlasCidrBlock string Required

CIDR block that Atlas uses for your clusters.

Atlas uses the specified CIDR block for all other VPC 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.

The Atlas CIDR block must be at least a /18 in one of the following private networks.

Lower Bound Upper Bound Prefix
10.0.0.0 10.255.255.255 10/8
172.16.0.0 172.31.255.255 172.16/12
192.168.0.0 192.168.255.255 192.168/16

Atlas locks this value if an M10+ cluster or a VPC 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 VPC Peering Connection to set the desired Atlas VPC CIDR block for that project.

Important

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

Example

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.

A project with an Atlas VPC CIDR block of /18 is limited to approximately 80 three-node replica sets per GCP region.

Contact MongoDB Support for any questions on Atlas limits of MongoDB nodes per VPC.
providerName string Optional Cloud provider for this VPC peering connection. If omitted, Atlas sets this parameter to AWS.
regionName string Required AWS Region.
