How can I configure the Splunk Add-on for Kafka to use a TLS/SSL certificate to authenticate with a Kafka server? It is necessary to connect to a CloudKafka instance.
An example Python implementation from their documentation:
ssl_context.verify_mode = ssl.CERT_REQUIRED ssl_context.check_hostname = True ssl_context.load_verify_locations("/tmp/ca.pem") ssl_context.load_cert_chain('/tmp/cert.pem', '/tmp/key.pem')
As mentioned in the Kafka doc (7.2.1), SSL is only supported in the new Consumer and Producer API. The Splunk for Kafka Add-on does not use this new API. See question: Is support for Kafka version 0.9 or higher in the pipeline any time soon?
Apache Kafka is using a dedicated port to establish secure communication between customers and brokers using SSL. You should enable it due to default setting as disable.
