Full Description

Confluent Platform Kafka REST Proxy

This is a highly configurable Dockerized Confluent Platform Kafka REST Proxy.

How to use this image

The container can be configured via environment variables where any Kafka REST Proxy property can be set after rp_ with underscore instead of period ('.') used. For example:

Environment Variable Property Default
rp_debug debug true
rp_id id kafka-rest-1
rp_port port 8082
rp_schema_registry_url schema.registry.url http://SR_PORT_8081_TCP_ADDR:SR_PORT_8081_TCP_PORT
rp_zookeeper_connect zookeeper.connect ZOOKEEPER_PORT_2181_TCP_ADDR:ZOOKEEPER_PORT_2181_TCP_PORT

A few sensible values have been set as given above. A basic invocation using a link to a local ZooKeeper, Kafka Broker and Schema Registry instance would be:

docker run --rm --name kafka-rest -p 8082:8082 --link zookeeper:zookeeper --link schema-registry:sr --link kafka:kafka cgswong/confluent-rest-proxy

Using your configuration file

The config directory, /etc/kafka-rest, is exposed for mounting to your local host. This facilitates using your own configuration file, instead of injecting into the container, while still take advantage of variable substitution. Also, you can download a remote properties file by setting the environment variable rp_cfg_url to the location of the file.


This image is a fork of the main ConfluentInc Platform. As I do contribute back you may see some of these features included, however, some may not be included or take longer to be merged. I created this version not only to contribute back to a really good project, but also to learn, and have a version which was more robust (production ready since this is being used as such), with a more timely update cycle (for the time being anyways).
