I intially referred to similar question here: https://stackoverflow.com/q/59480373

I changed the apiVersion i.e. apiVersion: extensions/v1beta1 to apiVersion: apps/v1, I am using kubeadm and 3 nodes running workers.

However in my yaml I do have matching label selecters

    labels:
      app: rabbitmq
      role: master
      tier: queue

and if I try to run the below yaml deployment : I get

The Deployment "rabbitmq" is invalid:

• spec.selector: Required value
• spec.template.metadata.labels: Invalid value: mapstringstring{"app":"rabbitmq", "role":"master", "tier":"queue"}: selector does not match template labels

rabbitmq.yaml
