This repository contains a docker compose deployment configuration for a Kafka service based on Confluent image. This configuration is made up of three Kafka brokers and one Zookeeper. Java Authentication and Authorization Service (JAAS) is used for SASL_PLAINTEXT username and password authentication without an SSL certificate.

In this configuration we are using SASL_PLAINTEXT user and passwor configuration to authenticate with the service. By default JAAS is used. In order to tell JAAS how to authorize clients, kafka_server_jaas.conf should be configured. This configuration file is going to mounted inside a voluem in directory /etc/kafka/configs. PlainLoginModule has been used for SASL_PLAINTEXT auth.
| Variable | Default Value | Note |
|---|---|---|
| username | theengineroom | User Name to be used for Auth |
| password | 1tY=ZP43t20 | Password to be used for Auth |
user_username |
1tY=ZP43t20 | username should be replaced with the actual username(theengineroom) |
You can simply deploy your configuration using docker compose by using this command:
docker-compose --env-file ./configs/env.dev -f KAFKA_SASL_PLAINTEXT-docker-compose.yml up
