In this recipe, we’ll learn how to fix the host name of components in an Apache Pinot cluster.
Pinot Version1.0.0
Codestartreedata/pinot-recipes/fixed-hostname

​
Prerequisites

To follow the code examples in this guide, you must install Docker locally.
  1. If you haven’t already, download recipes.
  2. In terminal, go to the recipe by running the following command:
cd pinot-recipes/recipes/fixed-hostname

​
Launch Pinot Cluster

You can spin up a Pinot Cluster by running the following command: 
docker-compose up
This command will run a single instance of the Pinot Controller, Pinot Server, Pinot Broker, Pinot Minion, and Zookeeper. You can find the docker-compose.yml file on GitHub. Navigate to the Pinot UI and you should see the following: Pinot UI showing fixed host names Fixed hostnames

​
Configuring fixed host names

Let’s have a look at the Docker Compose file to see how we did this. The commands to start the container for each component are described below: Controller 
StartController -zkAddress zookeeper-fixedhost:2181 -controllerHost pinot-controller-fixedhost
Broker 
StartBroker -zkAddress zookeeper-fixedhost:2181  -brokerHost pinot-broker-fixedhost
Server 
StartServer -zkAddress zookeeper-fixedhost:2181 -serverHost pinot-server-fixedhost
Minion 
StartMinion -zkAddress zookeeper-fixedhost:2181 -minionHost pinot-minion-fixedhost
