Race condition between container and cluster #89

Closed aarongorka closed 5 years ago

aarongorka commented 5 years ago

It looks like there is a race condition when creating a container and a cluster, as the cluster will create a "default" container which prevents you from creating your own container.

$ terraform apply
# group, whitelist, etc. created...

Error: Error applying plan:

1 error(s) occurred:

* mongodbatlas_container.main: 1 error(s) occurred:

* mongodbatlas_container.main: Error creating MongoDB Container: MongoDB Atlas: 409 A container already exists for group xxxxxxxxxxxxxxx.

I am using the "basic" example along with the "peering" example in the same Terraform stack as well as some AWS resources to accept + configure the peering.

Adding a depends_on = ["mongodbatlas_container.main"] to the cluster fixes the issue.
