Launch Pinot Cluster

You can spin up a Pinot Cluster by running the following command:

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
