             Summary: Mesos containerizer to support docker credential helpers for private docker registries
                 Key: MESOS-7522
                 URL: https://issues.apache.org/jira/browse/MESOS-7522
             Project: Mesos
          Issue Type: Wish
          Components: containerization
            Reporter: Mao Geng


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
