Creé un clúster en Digital Ocean (DC/OS 1.9) usando terraform siguiendo estas instrucciones aquí

Todo parece haberse instalado correctamente, para extraerlo de un repositorio docker privado, necesito agregar un archivo .docker comprimido a mi /core/home/ y recuperarlo durante la implementación incluyéndolo en mi JSON.

 "fetch":[ { "uri":"file:///home/core/docker.tar.gz" } ]

Según estas instrucciones: https://docs.mesosphere.com/1.9/deploying-services/momee/docker-creds-agent/

Y sigo recibiendo errores:

 Failed to launch container: Failed to fetch all URIs for container 'abc123-xxxxx' with exit status: 256

Al mirar los registros de uno de los agentes:
