The Packer and Artifact Registry features of Atlas will no longer be actively developed or maintained and will be fully decommissioned on Friday, May 31, 2018. "Atlas" has been renamed to Terraform Enterprise and the features being developed are focusing on Terraform.
As part of this, the old Terraform Enterprise registry at hashicorp.com has been decommed, so its no longer needed.
