Multiple cluster

Hi all ,

How do i setup a 2nd cluster on my local machine , assuming 1 cluster is already learning ?
Is there any official documentation which i should refer as i was not able to find anything suitable on internet

Thanks

Usually using something like docker containers to keep them separate.

yeah ,I know about docker containers , but i need to mock it on my local setup for some testing .
Is there any workaround ?

You can still use docker for that.

Otherwise you will need to manage the port numbers yourself, as you configure each node to talk to each other.
