Confluent Schema Registryv3.11+
Configure the Confluent Consume plugin to use the Confluent Schema Registry for message deserialization.
Prerequisites
-
Create an API key and secret in the cluster
Environment variables
-
BOOTSTRAP_SERVER_HOST: The bootstrap server host. -
API_KEY: The API key to use for authentication. -
API_SECRET: The API secret to use for authentication. -
KAFKA_TOPIC: The name of the Kafka topic to consume from. -
REGISTRY_URL: The URL of your Confluent Schema Registry instance. For example,http://schema-registry:8081.
Add this section to your kong.yaml configuration file:
