| # Camel-Kafka-connector RabbitMQ Sink |
| |
| ## Introduction |
| |
| This is an example for Camel-Kafka-connector RabbitMQ |
| |
| ## What is needed |
| |
| - A RabbitMQ instance |
| |
| ## Running Kafka |
| |
| ``` |
| $KAFKA_HOME/bin/zookeeper-server-start.sh $KAFKA_HOME/config/zookeeper.properties |
| $KAFKA_HOME/bin/kafka-server-start.sh $KAFKA_HOME/config/server.properties |
| $KAFKA_HOME/bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic mytopic |
| ``` |
| |
| ## Setting up the needed bits and running the example |
| |
| You'll need to setup the plugin.path property in your kafka |
| |
| Open the `$KAFKA_HOME/config/connect-standalone.properties` |
| |
| and set the `plugin.path` property to your choosen location |
| |
| In this example we'll use `/home/oscerd/connectors/` |
| |
| ``` |
| > cd /home/oscerd/connectors/ |
| > wget https://repo1.maven.org/maven2/org/apache/camel/kafkaconnector/camel-rabbitmq-kafka-connector/0.11.0/camel-rabbitmq-kafka-connector-0.11.0-package.tar.gz |
| > untar.gz camel-rabbitmq-kafka-connector-0.11.0-package.tar.gz |
| ``` |
| |
| ## Setting up RabbitMQ |
| |
| This examples require a running RabbitMQ instance, for simplicity the steps below show how to start RabbitMQ using Docker. First you'll need to run a RabbitMQ with management instance: |
| |
| [source,bash] |
| ---- |
| docker run -d --hostname my-rabbit --name some-rabbit rabbitmq:3-management |
| ---- |
| |
| Next, we need to check the address of the container |
| |
| [source,bash] |
| ---- |
| > docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_id |
| 172.17.0.2 |
| ---- |
| |
| In the configuration `.properties` file we use below the IP address of the RabbitMQ master node needs to be configured, replace the value `172.17.0.2` configuration property with the IP of the node obtained from Docker. |
| |
| Next through your browser go to http://<address>:15672 |
| and login with the credentials guest/guest |
| |
| Create a queue called 'queue'. |
| |
| Now it's time to setup the connectors |
| |
| Open the RabbitMQ Sink configuration file |
| |
| ``` |
| name=CamelRabbitmqSinkConnector |
| connector.class=org.apache.camel.kafkaconnector.rabbitmq.CamelRabbitmqSinkConnector |
| key.converter=org.apache.kafka.connect.storage.StringConverter |
| value.converter=org.apache.kafka.connect.storage.StringConverter |
| |
| topics=mytopic |
| |
| camel.component.rabbitmq.hostname=172.17.0.2 |
| camel.component.rabbitmq.portnumber=5672 |
| camel.sink.path.exchangeName=queue |
| camel.sink.endpoint.exchangeType=topic |
| camel.sink.endpoint.autoDelete=false |
| camel.sink.endpoint.queue=queue |
| camel.sink.endpoint.routingKey=key |
| ``` |
| |
| Now you can run the example |
| |
| ``` |
| $KAFKA_HOME/bin/connect-standalone.sh $KAFKA_HOME/config/connect-standalone.properties config/CamelRabbitmqSinkConnector.properties |
| ``` |
| |
| On a different terminal run the kafka-producer and you should see messages from Kafka arriving at RabbitMQ |
| |
| ``` |
| bin/kafka-console-producer.sh --topic mytopic --broker-list localhost:9092 |
| >test |
| >test1 |
| >test2 |
| >test3 |
| ``` |
| |
| At this point you should be able to get messages through the management console, so these are the steps needed: |
| |
| - Go to http://<address>:15672 |
| - Select the Queues tab |
| - Select the 'queue' Queue |
| - Select get Messages action |
| - Browse through the messages |
