Start Kafka service

The following commands will start a container with Kafka and Zookeeper running on mapped ports 2181 (Zookeeper) and 9092 (Kafka).

docker pull spotify/kafka
docker run -d -p 2181:2181 -p 9092:9092 --env ADVERTISED_HOST=kafka --env ADVERTISED_PORT=9092 --name kafka spotify/kafka

Why Spotify?

ADVERTISTED_HOST was set to kafka, which will allow other containers to be able to run Producers and Consumers.

Introduction

A minishift openshift cluster can be created with cluster metrics installed. Although I couldn't find a way to add metrics to an already created minishift VM instance, the steps below helped to get a new instance up and running easily.

Steps

Step 1 - Initialise minishift with metrics.

Create a fresh minishift VM with an openshift cluster using the below command. The --metrics parameter is the only additional thing I had to provide for minishift to start installing cluster metrics and Hawkular.

 $minishift start —metrics
