= Kubernetes Resources Quota Component

*Since Camel 2.17*

// HEADER START
*Only producer is supported*
// HEADER END

The Kubernetes Resources Quota component is one of xref:kubernetes.adoc[Kubernetes Components] which
provides a producer to execute kubernetes resource quota operations.


== Component Options

// component options: START
The Kubernetes Resources Quota component supports 3 options, which are listed below.


[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *basicPropertyBinding* (advanced) | Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | boolean
| *lazyStartProducer* (producer) | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | boolean
| *bridgeErrorHandler* (consumer) | Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | boolean

== Endpoint Options

// endpoint options: START
The Kubernetes Resources Quota endpoint is configured using URI syntax:

----
kubernetes-resources-quota:masterUrl
----

with the following path and query parameters:

=== Path Parameters (1 parameters):

=== Query Parameters (22 parameters):


[width="100%",cols="2,5,^1,2",options="header"]
|===

| *connectionTimeout* (advanced) | Connection timeout in milliseconds to use when making requests to the Kubernetes API server. |  | Integer
| *synchronous* (advanced) | Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). | false | boolean
| *caCertData* (security) | The CA Cert Data |  | String

== Spring Boot Auto-Configuration

When using Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

[source,xml]
----
<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-kubernetes-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>
----


The component supports 4 options, which are listed below.

By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | Boolean
| *camel.component.kubernetes-resources-quota.enabled* | Whether to enable auto configuration of the kubernetes-resources-quota component. This is enabled by default. |  | Boolean
| *camel.component.kubernetes-resources-quota.lazy-start-producer* | Whether the producer should be started lazy (on the first message).

== Supported producer operation

- listResourcesQuota
- listResourcesQuotaByLabels
- getResourcesQuota
- createResourcesQuota
- deleteResourcesQuota

== Kubernetes Resource Quota Producer Examples

- listResourcesQuota: this operation list the Resource Quotas on a kubernetes cluster

[source,java]
--------------------------------------------------------------------------------
from("direct:list").
    toF("kubernetes-resources-quota:///?kubernetesClient=#kubernetesClient&operation=listResourcesQuota").
    to("mock:result");
--------------------------------------------------------------------------------

This operation return a List of Resource Quotas from your cluster

- listResourcesQuotaByLabels:  this operation list the Resource Quotas by labels on a kubernetes cluster

[source,java]
--------------------------------------------------------------------------------
from("direct:listByLabels").process(new Processor() {

            @Override
            public void process(Exchange exchange) throws Exception {
                Map<String, String> labels = new HashMap<>();
                labels.put("key1", "value1");
                labels.put("key2", "value2");
                exchange.getIn().setHeader(KubernetesConstants.KUBERNETES_RESOURCES_QUOTA_LABELS, labels);
            }
        });
    toF("kubernetes-resources-quota:///?kubernetesClient=#kubernetesClient&operation=listResourcesQuotaByLabels").
    to("mock:result");
--------------------------------------------------------------------------------

This operation return a List of Resource Quotas from your cluster, using a label selector (with key1 and key2, with value value1 and value2)
