Recommended way to create a coordinator node with svc?

[vinylen]

Hey!

What is the current recommended way to create coordinator nodes using the operator? I've seen in the breaking changes for OpenSearch 3.0 that if we pass a empty list to node.roles, i.e. node.roles = [] it should default to be a coordinating only node. However, if i set the same via the operator, the node gets all of the roles except data.

Same here. When I set node.roles = [] in values.yaml,
