atlas api clusters createCluster
On this page
experimental: Creates one cluster in the specified project.
Clusters contain a group of hosts that maintain the same data set. This resource can create clusters with asymmetrically-sized shards. Each project supports up to 25 database deployments. To use this resource, the requesting API Key must have the Project Owner role. This feature is not available for serverless clusters.
Please note that using an instanceSize of M2 or M5 will create a Flex cluster instead. Support for the instanceSize of M2 or M5 will be discontinued in January 2026. We recommend using the createFlexCluster API for such configurations moving forward.
This command is autogenerated and corresponds 1:1 with the Atlas API endpoint https://www.mongodb.com/docs/atlas/reference/api-resources-spec/v2/#tag/Clusters/operation/createCluster.
For more information and examples, see the referenced API documentation linked above.
