How to fix host names

In this recipe, we’ll learn how to fix the host name of components in an Apache Pinot cluster.

​

Prerequisites

To follow the code examples in this guide, you must install Docker locally.

​

Navigate to recipe

1. If you haven’t already, download recipes.
2. In terminal, go to the recipe by running the following command:

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:

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
