Confluent Platform Kafka REST Proxy
500K+
This is a highly configurable Dockerized Confluent Platform Kafka REST Proxy.
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
The config directory, /etc/kafka-rest, is exposed for mounting to your local host. This facilitates using your own configuration file, kafka-rest.properties 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).
