Docker Intro

How to get Enricher image

You can pull the docker image from our registry:

$ docker pull wizzieio/enricher:latest

How to use this image

Enricher requires a running Kafka broker before it starts.


First, start a zookeeper container by executing:

$ docker run --rm --name zookeeper-svc --net=host wurstmeister/zookeeper

You can find more information about wurstmeister/zookeeper image here


Now, start a kafka broker container by executing:

$ docker run --rm --name kafka-broker --net=host -e KAFKA_ADVERTISED_HOST_NAME=localhost -e KAFKA_ZOOKEEPER_CONNECT=localhost:2181 -e KAFKA_ADVERTISED_PORT=9092 wurstmeister/kafka:

Start Enricher

Once kafka broker is up, we can start a Enricher container and link it to the kafka broker, and configuring the APPLICATION_ID environment variable with our custom app name:

$ docker run --rm --name my-enricher --net=host -e APPLICATION_ID=my-enricher-app -e KAFKA_BOOTSTRAP_SERVER=localhost:9092 wizzieio/enricher:latest

Now you can follow the base tutorial to test Enricher!
