Chapter 15. GenericKafkaListenerConfigurationBootstrap schema reference

Used in: GenericKafkaListenerConfiguration

Full list of GenericKafkaListenerConfigurationBootstrap schema properties

Configures bootstrap service settings for listeners.

Example configuration for the host, nodePort, loadBalancerIP, and annotations properties is shown in the GenericKafkaListenerConfiguration schema section.

15.1. Specifying alternative bootstrap addresses
Link kopieren

To specify alternative names for the bootstrap address, use the alternativeNames property. This property is applicable to all types of listeners. The names are added to the broker certificates and can be used for TLS hostname verification.

Example route listener configuration with additional bootstrap addresses

listeners:
  #...
  - name: external1
    port: 9094
    type: route
    tls: true
    configuration:
      bootstrap:
        alternativeNames:
          - example.hostname1
          - example.hostname2
# ...

PropertyProperty typeDescription

alternativeNames

string array

Additional alternative names for the bootstrap service. The alternative names will be added to the list of subject alternative names of the TLS certificates.

host

string

Specifies the hostname used for the bootstrap resource. For route (optional) or ingress (required) listeners only. Ensure the hostname resolves to the Ingress endpoints; no validation is performed by Streams for Apache Kafka.

nodePort

integer

Node port for the bootstrap service. For nodeport listeners only.

loadBalancerIP

string

The loadbalancer is requested with the IP address specified in this property. This feature depends on whether the underlying cloud provider supports specifying the loadBalancerIP when a load balancer is created. This property is ignored if the cloud provider does not support the feature. For loadbalancer listeners only.

annotations

map

Annotations added to Ingress, Route, or Service resources. You can use this property to configure DNS providers such as External DNS. For loadbalancer, nodeport, route, or ingress listeners only.

labels

map

Labels added to Ingress, Route, or Service resources. For loadbalancer, nodeport, route, or ingress listeners only.

externalIPs

string array

External IPs associated to the nodeport service. These IPs are used by clients external to the OpenShift cluster to access the Kafka brokers. This property is helpful when nodeport without externalIP is not sufficient. For example on bare-metal OpenShift clusters that do not support Loadbalancer service types. For nodeport listeners only.
