Kubernetes - install the agent only on the desired nodes

If the client has multiple nodes but, for some reason, instana agent shouldn't monitor all nodes, then the client can install the agent only on desired nodes by using NodeAfinity property.

Example:

apiVersion: v1
kind: Pod
metadata:
  name: with-node-affinity
spec:
  affinity:
    nodeAffinity:
      requiredDuringSchedulingIgnoredDuringExecution:
        nodeSelectorTerms:
        - matchExpressions:
          - key: kubernetes.io/e2e-az-name
            operator: In
            values:
            - e2e-az1
            - e2e-az2
