| # Camel-Kafka-connector Exec Sink |
| |
| This is an example for Camel-Kafka-connector Exec Sink |
| |
| ## Standalone |
| |
| ### What is needed |
| |
| - The touch command |
| |
| ### 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-exec-kafka-connector/0.9.0/camel-exec-kafka-connector-0.9.0-package.tar.gz |
| > untar.gz camel-exec-kafka-connector-0.9.0-package.tar.gz |
| ``` |
| |
| Now it's time to setup the connectors |
| |
| Open the Exec sink configuration file |
| |
| ``` |
| name=CamelExecSinkConnector |
| connector.class=org.apache.camel.kafkaconnector.exec.CamelExecSinkConnector |
| key.converter=org.apache.kafka.connect.storage.StringConverter |
| value.converter=org.apache.kafka.connect.storage.StringConverter |
| |
| topics=mytopic |
| |
| camel.sink.path.executable=touch |
| camel.sink.endpoint.args=/tmp/${body}-${headers.detail}.txt |
| ``` |
| |
| Set the correct options in the file. |
| |
| Now you can run the example |
| |
| ``` |
| $KAFKA_HOME/bin/connect-standalone.sh $KAFKA_HOME/config/connect-standalone.properties config/CamelExecSinkConnector.properties |
| ``` |
| |
| You'll need to send messages to mytopic. You can run the simple producer included in this project. So cd in the folder: |
| |
| ``` |
| > cd camel-kafka-exec-simple-producer |
| > mvn compile exec:exec -Dkafka.topic.name=mytopic -Dkafka.key=1 -Dcamel.body="FileName" -Dcamel.header.detail="detail1" |
| ``` |
| |
| Under tmp folder you should see the file created |
| |
| ``` |
| > cd /tmp/ |
| > ls | grep FileName |
| FileName-detail1.txt |
| ``` |
| |
| In the mytopic topic you should see the message too |
| |
| ``` |
| > ./kafkacat -b localhost:9092 -t mytopic -f 'Headers: %h: Message value: %s\n' |
| Headers: CamelHeader.detail=detail1: Message value: FileName |
| % Reached end of topic mytopic [0] at offset 1 |
| ``` |
