Not able to create M0 clusters

[jackivanov]

Hello,

For some reason I can't create M0 clusters via terraform. Meanwhile I can do it in the UI.

resource "mongodbatlas_cluster" "default" {
  name                        = "M0"
  project_id                  = mongodbatlas_project.backend.id
  provider_name               = "GCP"
  provider_region_name        = "WESTERN_EUROPE"
  provider_instance_size_name = "M0"
}

Error: error creating MongoDB Cluster: POST https://cloud.mongodb.com/api/atlas/v1.0/groups/XXX/clusters: 400 (request "Bad Request") An invalid enumeration value M0 was specified.

resource "mongodbatlas_cluster" "default" {
  name                        = "M0"
  project_id                  = mongodbatlas_project.backend.id
  provider_name               = "TENANT"
  provider_region_name        = "WESTERN_EUROPE"
  provider_instance_size_name = "M0"
}

API Access | You cannot modify or configure an M0 Free Tier cluster using the Clusters API endpoint. A subset of API endpoints support M2 and M5 shared clusters.

@jackivanov I'm getting same error for M2/M5 clusters with AWS. Based on docs it should be available https://docs.atlas.mongodb.com/reference/api/clusters-create-one/ 🤔 ?

All right, figure it out using correct provider_name and backing_provider_name for M2/M5:

auto_scaling_disk_gb_enabled = false

//Provider Settings "block"
provider_name = "TENANT"
backing_provider_name = "AWS"
disk_size_gb = 2
provider_instance_size_name = "M2"
