Terraform tries to change network settings of running compute instances if another is added #18

Open 0xErnie opened 6 years ago

0xErnie commented 6 years ago

Whenever I increase "instance_count" in the minimal example, terraform suggests that all compute instances should be "destroyed and recreated" and the fails applying this change.

I don't understand why running instances have to be destroyed and recreated and this should not fail.

Terraform v0.11.2 + provider.openstack v1.2.0

terraform apply -var-file=parameter.tvars

Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure.
