How do I pull Docker images from the Tutum private registry with Amazon ECS?

Question

I am trying to set up an Amazon ECS deployment which employs an image from the Tutum private Docker registry. Tutum being private, it requires authenticating obviously.

As per the ECS documentation , I've modified the file '/etc/ecs/ecs.config' on the EC2 instance to contain the correct authentication credentials for Tutum:

ECS_ENGINE_AUTH_TYPE=dockercfg
ECS_ENGINE_AUTH_DATA={"tutum.co":{"auth":"<auth-string>","email":"<my-email>"}}

The auth string is a Base64 encoding of my Tutum credentials: '<username>:<password>' .

However, when I try to run the corresponding ECS task, it fails with this message: CannotPullContainerError: Authentication is required .

How do I properly configure ECS to authenticate against the Tutum registry, so I can successfully pull images from there?

似乎是要重新启动EC2实例，以便应用“ /etc/ecs/ecs.config”中的设置。
