Chapter 58. Kubernetes ConfigMap Since Camel 2.17 Both producer and consumer are supported The Kubernetes ConfigMap component is one of the Kubernetes Components which provides a producer to execute Kubernetes ConfigMap operations and a consumer to consume events related to ConfigMap objects. 58.1. Dependencies When using kubernetes-config-maps with Red Hat build of Apache Camel for Spring Boot, use the following Maven dependency to have the support for auto configuration: <dependency> <groupId>org.apache.camel.springboot</groupId> <artifactId>camel-kubernetes-starter</artifactId> </dependency> 58.2. Configuring Options Camel components are configured on two separate levels: component level endpoint level 58.2.1. Configuring Component Options The component level is the highest level which holds general and common configurations that are inherited by the endpoints. For example a component may have security settings, credentials for authentication, urls for network connection and so forth. Some components only have a few options, and others may have many. Because components typically have pre configured defaults that are commonly used, then you may often only need to configure a few options on a component; or none at all. Configuring components can be done with the Component DSL , in a configuration file (application.properties|yaml), or directly with Java code. 58.2.2. Configuring Endpoint Options Where you find yourself configuring the most is on endpoints, as endpoints often have many options, which allows you to configure what you need the endpoint to do. The options are also categorized into whether the endpoint is used as consumer (from) or as a producer (to), or used for both. Configuring endpoints is most often done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL as a type safe way of configuring endpoints. A good practice when configuring options is to use Property Placeholders , which allows to not hardcode urls, port numbers, sensitive information, and other settings. In other words placeholders allows to externalize the configuration from your code, and gives more flexibility and reuse. The following two sections lists all the options, firstly for the component followed by the endpoint. 58.3. Component Options The Kubernetes ConfigMap component supports 4 options, which are listed below. Name Description Default Type kubernetesClient (common) Autowired To use an existing kubernetes client. KubernetesClient 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 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 autowiredEnabled (advanced) Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc. true boolean 58.4. Endpoint Options The Kubernetes ConfigMap endpoint is configured using URI syntax: with the following path and query parameters: 58.4.1. Path Parameters (1 parameters) Name Description Default Type masterUrl (common) Required Kubernetes Master url. String 58.4.2. Query Parameters (33 parameters) Name Description Default Type apiVersion (common) The Kubernetes API Version to use. String dnsDomain (common) The dns domain, used for ServiceCall EIP. String kubernetesClient (common) Default KubernetesClient to use if provided. KubernetesClient namespace (common) The namespace. String portName (common) The port name, used for ServiceCall EIP. String portProtocol (common) The port protocol, used for ServiceCall EIP. tcp String crdGroup (consumer) The Consumer CRD Resource Group we would like to watch. String crdName (consumer) The Consumer CRD Resource name we would like to watch. String crdPlural (consumer) The Consumer CRD Resource Plural we would like to watch. String crdScope (consumer) The Consumer CRD Resource Scope we would like to watch. String crdVersion (consumer) The Consumer CRD Resource Version we would like to watch. String labelKey (consumer) The Consumer Label key when watching at some resources. String labelValue (consumer) The Consumer Label value when watching at some resources. String poolSize (consumer) The Consumer pool size. 1 int resourceName (consumer) The Consumer Resource Name we would like to watch. String bridgeErrorHandler (consumer (advanced)) 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 exceptionHandler (consumer (advanced)) To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option 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 (advanced)) Sets the exchange pattern when the consumer creates an exchange. Enum values: InOnly InOut ExchangePattern operation (producer) Producer operation to do on Kubernetes. String lazyStartProducer (producer (advanced)) 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 connectionTimeout (advanced) Connection timeout in milliseconds to use when making requests to the Kubernetes API server. Integer 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.

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-services.enabled Whether to enable auto configuration of the kubernetes-services component.

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.
