+```sh
+kafka:
+  clusters:
+    -
+      name: local
+      bootstrapServers: localhost:29091
+      zookeeper: localhost:2183
+      schemaRegistry: http://localhost:8085
+#     schemaNameTemplate: "%s-value"
+      jmxPort: 9997
+    -
+```

+* `name`: specifying the certificate for authenticating brokers, if TLS is enabled.
+* `bootstrapServers`: specifying the certificate for authenticating brokers, if TLS is enabled.
+* `zookeeper`: specifying the certificate for authenticating brokers, if TLS is enabled.
+* `schemaRegistrys`: specifying the certificate for authenticating brokers, if TLS is enabled.
+* `schemaNameTemplate`: specifying the certificate for authenticating brokers, if TLS is enabled.
+* `jmxPort`: specifying the certificate for authenticating brokers, if TLS is enabled.
