| [id="extensions-kubernetes-configuration-automatic-registration-of-a-kubernetes-client-instance"] |
| === Automatic registration of a Kubernetes Client instance |
| |
| The extension automatically registers a Kubernetes Client bean named `kubernetesClient`. You can reference the bean in your routes like this: |
| |
| from("direct:pods") |
| .to("kubernetes-pods:///?kubernetesClient=#kubernetesClient&operation=listPods") |
| |
| By default the client is configured from the local kubeconfig file. You can customize the client configuration via properties within `application.properties`: |
| |
| [source,properties] |
| ---- |
| quarkus.kubernetes-client.master-url=https://my.k8s.host |
| quarkus.kubernetes-client.namespace=my-namespace |
| ---- |
| |
| The full set of configuration options are documented in the https://quarkus.io/guides/kubernetes-client#quarkus-kubernetes-client_configuration[Quarkus Kubernetes Client guide]. |
| |
| [id="extensions-kubernetes-configuration-having-only-a-single-consumer-in-a-cluster-consuming-from-a-given-endpoint"] |
| === Having only a single consumer in a cluster consuming from a given endpoint |
| |
| When the same route is deployed on multiple pods, it could be interesting to use this extension in conjunction with the xref:reference/extensions/master.adoc[Master one]. |
| In such a setup, a single consumer will be active at a time across the whole camel master namespace. |
| |
| For instance, having the route below deployed on multiple pods: |
| |
| ``` |
| from("master:ns:timer:test?period=100").log("Timer invoked on a single pod at a time"); |
| ``` |
| |
| It's possible to enable the kubernetes cluster service with a property like below: |
| |
| ``` |
| quarkus.camel.cluster.kubernetes.enabled = true |
| ``` |
| |
| As a result, a single consumer will be active across the `ns` camel master namespace. |
| It means that, at a given time, only a single timer will generate exchanges across the whole cluster. |
| In other words, messages will be logged every 100ms on a single pod at a time. |
| |
| The kubernetes cluster service could further be tuned by tweaking `quarkus.camel.cluster.kubernetes.*` properties. |
