+6) JMX exporter for kafka. Seems like docker container jmx exporter working as http server doesn't work with custom configs and tries to connect to localhost for some damn reason. So doesn't need to be used. Used javaagent for kafka container 
+   ```docker
+      - "KAFKA_JMX_OPTS=-javaagent:/prometheus/jmx_prometheus_javaagent-1.0.1.jar=12345:/prometheus/kafka-kraft-config-3_0_0.yml -Dcom.sun.management.jmxremote.rmi.port=12345 -Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.authenticate=false  -Dcom.sun.management.jmxremote.ssl=false"
+   ```
+
+   ```yml
+  # for some unknown reason exporter tries to connect to localhost even if you define hostPort in config.yml.
+  # broken stuff.
+  jmx-exporter:
+    image: 'docker.io/bitnami/jmx-exporter:1.0.1'
+    container_name: jmx-exporter
+    ports:
