Elastic logging

I have a small on prem cluster here at home running on a couple VMs.

I am interested in doing some elastic search. I have been looking at some different setups. Looks like there are 2 options here.

  1. just deploy elastic as one of my deployments
  2. deploy elastic in the kube-system namespace and set kube logging to use elastic

I have a couple questions for anyone that may have elastic in your cluster.

do you have it in the kube-system? can elastic be used by third party stuff if it’s in the kube-system namespace?

if you aren’t running it in the system name space. Are you running a single pod elastic? or something more?

Any suggestions would be appreciated. Thanks!
