Mao Geng updated MESOS-7522:
----------------------------
    Description: 
In Pinterest, we use Amazon ECR as our docker registry and use 
https://github.com/awslabs/amazon-ecr-credential-helper to let docker engine to 
get auth token automatically. 

It works well with docker containerizer, as long as I have the 
.docker/config.json configured "credStores" and --docker_config configured for 
mesos-agent. 

However, this doesn't work for mesos containerizer. Meanwhile we want to use 
mesos containerizer's GPU support, so we have to run a separate docker registry 
on http and without auth, purely for mesos containerizer. 

I think it will be good if mesos containerizer can support 
https://github.com/docker/docker-credential-helpers by default, so that it will 
address a pain point for the users who are using crendential helpers with 
private registries on ECR, GCR, quay, dockerhub etc. 

This might be related to MESOS-7088
