Hey @elreydetoda,
https://hub.docker.com/u/hashicorp is indeed the official account for HashiCorp’s Docker Images ^1
We currently provide two official images:
1.) Consul via hub.docker.com/_/consul
2.) Vault via hub.docker.com/_/vault
As these are marked as official images, they are moved to a different namespace and therefore not directly visible when you search the list of images that are available as part of the HashiCorp organization on Docker Hub.
Packer and Terraform, while available as images, are a bit more involved to use (as you experienced in your post).
Hope this provides some insights!
