View the Change Log to see what has changed.

Getting Started

Install Confluent Package

If you include the recipe[confluent] this will install the Confluent package and nothing else.

You can find the package installed under /opt/confluent (by default) with the name confluent-VERSION.

You can also find the configuration under,

  • /etc/kafka
  • /etc/kafka-rest
  • /etc/schema-registry
  • /etc/kafka-connect

Kafka Service

If you include the recipe[confluent::kafka] this will install the Confluent package, configure and start the Kafka service.

You can configure the service using the attribtues node["confluent"]["kafka"]["server.properties"][...] = .... Use Confluent's Kafka doc to figure out the appropriate configuration for yourself.

You can find the SysV script at /etc/init.d/kafka-rest or service kafka-rest [start|stop|restart|status].

You can find the logs at /var/log/confluent/kafka.log.

Kafka REST Service

If you include the recipe[confluent::kafka-rest] this will install the Confluent package, configure and start the Kafka REST service.

You can configure the service using the attribtues node["confluent"]["kafka-rest"]["kafka-rest.properties"][...] = .... Use Confluent's Kafka REST doc to figure out the appropriate configuration for yourself.

You can find the SysV script at /etc/init.d/kafka-rest or service kafka-rest [start|stop|restart|status].

You can find the logs at /var/log/confluent/kafka-rest.log.

Schema Registry Service

If you include the recipe[confluent::schema-registry] this will install the Confluent package, configure and start the Schema Registry service.

You can configure the service using the attribtues node["confluent"]["schema-registry"]["schema-registry.properties"][...] = .... Use Confluent's Schema Registry doc to figure out the appropriate configuration for yourself.

You can find the SysV script at /etc/init.d/schema-registry or service schema-registry [start|stop|restart|status].

You can find the logs at /var/log/confluent/schema-registry.log.

Kafka Connect

If you include the recipe[confluent::kafka-connect] this will install the Confluent package, configure and start the Kafka connector. This will listen on port 8083 exposing its rest api to control spinning up new connectors.

You can configure the service using the attribtues node["confluent"]["kafka-connect"]["worker.properties"][...] = .... Use Confluent's Kafka Connect doc to figure out the appropriate configuration for yourself.

You can find the SysV script at /etc/init.d/kafka-connect or service kafka-connect [start|stop|restart|status].

You can find the logs at /var/log/confluent/kafka-connect.log.

Zookeeper (For development purposes only)

If you include the recipe[confluent::zookeeper] this will install the Confluent package and start a zookeeper process. It will listen on port 2181. This is a single zookeeper worker and is not recomended for production use. The primary purpose of this recipe is to get everything running inside vagrant as a self contained system without having to run process on the host machine.
