Chapter 186. Kubernetes Component (deprecated)
Available as of Camel version 2.17
The composite kubernetes component has been deprecated. Use individual component splitted as following.
- Kubernetes Build Config
- Kubernetes Build
- Kubernetes ConfigMap
- Kubernetes Namespace
- Kubernetes Node
- Kubernetes Persistent Volume
- Kubernetes Persistent Volume Claim
- Kubernetes Pod
- Kubernetes Replication Controller
- Kubernetes Resource Quota
- Kubernetes Secrets
- Kubernetes Service Account
- Kubernetes Service
The Kubernetes component is a component for integrating your application with Kubernetes standalone or on top of Openshift.
Maven users will need to add the following dependency to their pom.xml for this component:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-kubernetes</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>186.1. URI format
kubernetes:masterUrl[?options]
You can append query options to the URI in the following format, ?option=value&option=value&…
186.2. Options
The Kubernetes component has no options.
The Kubernetes endpoint is configured using URI syntax:
kubernetes:masterUrl
with the following path and query parameters:
186.2.1. Path Parameters (1 parameters):
| Name | Description | Default | Type |
|---|---|---|---|
| masterUrl | Required Kubernetes Master url | String |
186.2.2. Query Parameters (28 parameters):
| Name | Description | Default | Type |
|---|---|---|---|
| apiVersion (common) | The Kubernetes API Version to use | String | |
| category (common) | Required Kubernetes Producer and Consumer category | String | |

| kubernetesClient (common) | Default KubernetesClient to use if provided | KubernetesClient | |
| portName (common) | The port name, used for ServiceCall EIP | String | |
| 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 |

| resourceName (consumer) | The Consumer Resource Name we would like to watch | String | |
| exceptionHandler (consumer) | To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored. | ExceptionHandler | |
| exchangePattern (consumer) | Sets the exchange pattern when the consumer creates an exchange. | ExchangePattern | |
| operation (producer) | Producer operation to do on Kubernetes | String | |
| 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 | |
| caCertFile (security) | The CA Cert File | String | |
| clientCertData (security) | The Client Cert Data | String | |
| clientCertFile (security) | The Client Cert File | String | |
| clientKeyAlgo (security) | The Key Algorithm used by the client | String | |
| clientKeyData (security) | The Client Key data | String | |
| clientKeyFile (security) | The Client Key file | String | |
| clientKeyPassphrase (security) | The Client Key Passphrase | String | |

| username (security) | Username to connect to Kubernetes | String |

186.5. Usage
186.5.1. Producer examples
Here we show some examples of producer using camel-kubernetes.
186.5.2. Create a pod
from("direct:createPod")
.toF("kubernetes://%s?oauthToken=%s&category=pods&operation=createPod", host, authToken);By using the KubernetesConstants.KUBERNETES_POD_SPEC header you can specify your PodSpec and pass it to this operation.
186.5.3. Delete a pod
from("direct:createPod")
.toF("kubernetes://%s?oauthToken=%s&category=pods&operation=deletePod", host, authToken);By using the KubernetesConstants.KUBERNETES_POD_NAME header you can specify your Pod name and pass it to this operation.
