Elastic cattle for rancher 2.0

Dear community,
we had so far with rancher 1.x the possibility to deploy ready-to-use elasticsearch nodes using cattles.
I did not find anything similar in the new rancher 2.0.

  1. Is this possibility still there, meaning a cattle hub for rancher 2.0?
  2. Is there a good documentation on how to build own cattles in / for 2.0?

Thank you for every insight comment - I am a newbie with rancher.
