Example Playbook

Here’s a simple example to install ZooKeeper:

- name: Installing ZooKeeper
  hosts: all
  sudo: yes
  roles:
    - role: humio.zookeeper

Cluster Example

For setting up a ZooKeeper cluster, use this example:

- name: Zookeeper cluster setup
  hosts: zookeepers
  sudo: yes
  roles:
    - role: humio.zookeeper
      zookeeper_hosts: "{{groups['zookeepers']}}"

In this example, zookeepers should be a hosts group defined in your inventory file:

[zookeepers]
server[1:3]

Custom IP per Host Group

To specify custom IPs for each host in the group, use:

zookeeper_hosts: "
    {%- set ips = [] %}
    {%- for host in groups['zookeepers'] %}
    {{- ips.append(dict(id=loop.index, host=host, ip=hostvars[host]['ansible_default_ipv4'].address)) }}
    {%- endfor %}
    {{- ips -}}"
