ConfigMap example about kubernetes-elasticsearch-cluster HOT 7 OPEN

@puja108 the second one as it will make things easier for me when implementing the operator.

@pires I can take it. Was looking through the yamls to see how to slice the Config Maps. There's two options:

• 1 for each deployment (master, data, client)
• 1 shared one (with cluster name etc in it) + 1 additional for the differences in envs for each deployment

First option is easier and maybe adds clarity. Second option removes redundancy and reduces the chance to have typos in e.g. cluster names. WDYT?

That would be cool.

@puja108 another one for you, maybe? 👍

Yeah, I was also thinking of making the ES config a Config Map.

Hi! I am trying to set up with a ConfigMap and instantly getting the error:
