Overview

This guide will help you install, configure and use your custom Kafka deserializer with Console which will present serialized messages in a human readable way.

​
Prerequisites

Your custom deserializer is available and you know how to configure it. Check out some examples of Kafka deserializer implementations

​
Install custom deserializer

Console looks for jars present in folder /opt/conduktor/plugins during startup. There are different ways of making your custom deserializers available in Console. 
conduktor-console:
  image: conduktor/conduktor-console
  ports:
    - '8080:8080'
  volumes:
    - /local/my_custom_deserializers_2.13-2.0.0.jar:/opt/conduktor/plugins/my_custom_deserializers_2.13-2.0.0.jar

​
Check installation status

If everything went well, you should see this on the Console startup: 
Loading plugin my_custom_deserializers_2.13-2.0.0 from jar: /opt/conduktor/plugins/my_custom_deserializers_2.13-2.0.0.jar
Register custom Kafka Deserializer: class io.example.conduktor.custom.deserializers.MyCustomDeserializer
Register custom Kafka Deserializer: class io.example.conduktor.custom.deserializers.MyCustomProtobufDeserializer
...

​
Configure custom deserializer and consume data

From the Consume page, open the Value Format filter and pick your Custom Deserializer from the list.
