Confluent Platform Schema Registry
10K+
This is a highly configurable Dockerized Confluent Platform Schema Registry.
The container can be configured via environment variables where any Schema Registry property can be set after sr_
with underscore instead of period ('.') used. For example:
Environment Variable | Property | Default |
---|---|---|
sr_debug | debug | true |
sr_kafkastore_connection_url | kafkastore.connection.url | ZOOKEEPER_PORT_2181_TCP_ADDR:ZOOKEEPER_PORT_2181_TCP_PORT |
sr_kafkastore_topic | kafkastore.topic | _schemas |
sr_schema_registry_zk_namespace | schema.registry.zk.namespace | schema_registry |
sr_port | port | 8081 |
A few sensible values have been set as given above. A basic invocation using a link to a local ZooKeeper instance would be:
docker run --rm --name schema-registry -p 8081:8081 --link zookeeper:zookeeper cgswong/confluent-schema-registry
The config directory, /etc/schema-registry
, is exposed for mounting to your local host. This facilitates using your own configuration file, schema-registry.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 sr_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).
