'How to start a process (or Kafka to be specific) on remote host with Ansible Playbook

How to start Zookeeper and Kafka broker on remote target with Ansible Playbook.

Following commands work fine locally.

Start Zookeeper: cd /opt/kafka ./bin/zookeeper-server-start.sh config/zookeeper.properties

Start Kafka Broker: (setting 2 env variables while starting) JMX_PORT="5555" KAFKA_HEAP_OPTS="-Xms500M -Xmx550M" ./bin/kafka-server-start.sh config/server.properties

Solution 1:[1]

I'd recommend creating a systemd service file that you can start/stop appropriately using the Ansible service module.

Confluent offers cp-ansible repo that you can either copy from, or use directly to install a Kafka + Zookeeper cluster (and more)

Solution 2:[2]

You can use either the modules shell, command

Using command, I think something like that should work:

- name: Start Zookeeper
  command:
    cmd:  ./bin/zookeeper-server-start.sh config/zookeeper.properties
    chdir:  /opt/kafka

- name: Start Kafka broker
  command:
    cmd: 'JMX_PORT="5555" KAFKA_HEAP_OPTS="-Xms500M -Xmx550M" ./bin/kafka-server-start.sh config/server.properties'
    chdir: /opt/kafka
