Console Clients	none	client properties, e.g. producer.config or consumer.config
Connect workers	none, and `producer.` or `consumer.`	`etc/kafka/connect-distributed.properties`
Control Center	`confluent.controlcenter.streams.`	`etc/confluent-control-center/control-center.properties`
Java Clients	Java clients use static parameters defined in the Javadoc: SSL SASL	SslConfigs or SaslConfigs in Properties class
Metrics Reporter	`confluent.metrics.reporter.`	`etc/kafka/server.properties`
Monitoring Interceptors in clients	`confluent.monitoring.interceptor.`	client properties, e.g. producer.config or consumer.config
Monitoring Interceptors in Connect	`producer.confluent.monitoring.interceptor.` `consumer.confluent.monitoring.interceptor.`	`etc/kafka/connect-distributed.properties`
Monitoring Interceptors in Replicator	`src.consumer.confluent.monitoring.interceptor.`	connector JSON file (not the worker properties file)

Environment Variables for Configuring HTTPS¶

If a component in the Confluent Platform needs to connect to a service via HTTPS, for example to a HTTPS-enabled Confluent Schema Registry, you may need to configure the SSL credentials for that HTTPS connection. This table shows for each component, the name of the environment variable to configure with SSL credentials for those HTTPS connections.

Component	Environment Variable
Broker	`KAFKA_OPTS`
Console Clients	`KAFKA_OPTS`
KSQL	`KSQL_OPTS`
Connect workers	`KAFKA_OPTS`
Control Center	`CONTROL_CENTER_OPTS`
Schema Registry	`SCHEMA_REGISTRY_OPTS`
REST Proxy	`KAFKAREST_OPTS`

Additional Environment Variables¶

If you using the Schema Registry ACL Authorizer with SASL, pass in JAAS configuration file using the SECURITY_PLUGINS_OPTS environment variable before calling sr-acl-cli.
