Zen Discovery and the transport ports

Elastic Stack Elasticsearch
2

Hi again,

it is probably unclear, what I want to achieve.
I try to say it in a few sentences:

  1. We want to scale dockerized Elasticsearch nodes horizontally.
  2. Potentially, multiple nodes can live on the same host.
  3. There has to be a configuration so that they automatically use a port between 93xx and 93yy without conflicting with other instances on the same host.
  4. They eventually need to discover the cluster.

Please help me finding this configuration.
Regards
