From 472097d7ebda980063f5fbe195b8b2c3f72bbf46 Mon Sep 17 00:00:00 2001 From: Steven Fitzpatrick Date: Fri, 29 Nov 2019 16:48:08 -0600 Subject: [PATCH] Kafka - Implement SASL Authentication This change implements SASL authentication in the Kafka chart. Kafka and Exporter credentials are defined in the endpoints section, while other credentials for producers and consumers can be defined in the jaas section. Additionally, a few server settings are provided to enable SASL auth, and a jvm_options key is introduced. Any options specified here will be set when starting Kafka, including the location of the jaas file in this case.
