## @param externalAccess.service.nodePorts Array of node ports used for each Kafka broker. Length must be the same as replicaCount

nodePorts: []
## @param externalAccess.service.externalIPs Use distinct service host IPs to configure Kafka external listener when service type is NodePort. Length must be the same as replicaCount

## Network policies
## Ref: https://kubernetes.io/docs/concepts/services-networking/network-policies/
##
networkPolicy:
## @param networkPolicy.enabled Specifies whether a NetworkPolicy should be created
##
enabled: false
## @param networkPolicy.allowExternal Don't require client label for connections
## When set to false, only pods with the correct client label will have network access to the port Kafka is
## listening on. When true, zookeeper accept connections from any source (with the correct destination port).
##
allowExternal: true
## @param networkPolicy.explicitNamespacesSelector A Kubernetes LabelSelector to explicitly select namespaces from which traffic could be allowed
## If explicitNamespacesSelector is missing or set to {}, only client Pods that are in the networkPolicy's namespace
## and that match other criteria, the ones that have the good label, can reach the kafka.
## But sometimes, we want the kafka to be accessible to clients from other namespaces, in this case, we can use this
## LabelSelector to select these namespaces, note that the networkPolicy's namespace should also be explicitly added.
##
## e.g:
## explicitNamespacesSelector:
## matchLabels:
## role: frontend
## matchExpressions:
## - {key: role, operator: In, values: [frontend]}
##
explicitNamespacesSelector: {}
## @param networkPolicy.externalAccess.from customize the from section for External Access on tcp-external port
