             Summary: Pass credentials to the agent for executor authentication and fetching
                 Key: MESOS-6365
                 URL: https://issues.apache.org/jira/browse/MESOS-6365
             Project: Mesos
          Issue Type: Epic
          Components: slave
            Reporter: Greg Mann


Three features are currently driving the need for a mechanism to pass secrets/credentials from the master to the agent:
* HTTP executor authentication
* Container image fetching
* Artifact fetching

We currently provide the ability to authenticate with a Docker registry, but the credentials used for this may only be set once on the agent via a command-line flag. Allowing operators to specify a Docker credential on a per-task basis requires a secret-passing mechanism.

We should design and implement a method for passing secrets that will work in all three of these scenarios.
