How to enter Credentials for Docker Container Downloads?

[#1]

I'm trying to build a Docker container from Cloudera's repo but am getting an authentication error. This is the beginning of my .docker file:

FROM docker.repository.cloudera.com/cdsw/engine:13

I have the credentials from the generator and can easily pull-down things via wget but how do I tell the docker engine to use the credentials when it goes to retrieve the engine from the cloudera repo?

@akshay0103  Could you please check with your account team of a new docker credentials or getting the existing one activated or create an administrative case.
