Debug Output

P.S Had to take only the bottom part of the logs as they contain my docker credentials

Expected Behavior

Expect the image to be pulled

Actual Behavior

Image should be pulled correctly

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. terraform apply

Important Factoids

• I am using terragrunt
• Host is an ssh based connection to a remove VM
• I've already ran docker login within the VM. Pulling manually worked fine
• I'm logged in under the same user in both VM and local machine
• Pulling image locally works fine as well

@WhoAteDaCake I thought I was having this same issue, i wasn't, turned out to be the image name was wrong (i'm pretty new to docker). In either case, the docs indicate that the registry_auth block is only for targetting v2 of the API. for me the following block worked.

provider docker {
  host = "ssh://user@xxx.xxx.x.xxx"
  registry_auth {
      address = "registry.hub.docker.com"
      username = "user"
      password = "access-token"
  }
}

Using the registry auth + manual username/password worked. Thank you @jbruett
