示例剧本

- name: 安装 ZooKeeper
  hosts: all
  sudo: yes
  roles:
    - role: AnsibleShipyard.ansible-zookeeper

从 S3 获取压缩包的示例

- name: 安装 ZooKeeper
  hosts: all
  sudo: yes
  vars:
    zookeeper_archive_s3_bucket: my-s3-bucket
    zookeeper_archive_s3_object: my/s3/directory/zookeeper-{{zookeeper_version}}.tar.gz
  roles:
    - role: AnsibleShipyard.ansible-zookeeper

集群示例

- name: ZooKeeper 集群设置
  hosts: zookeepers
  sudo: yes
  roles:
    - role: AnsibleShipyard.ansible-zookeeper
      zookeeper_hosts: "{{groups['zookeepers']}}"

假设 zookeepers 是在库存文件中定义的主机组。

[zookeepers]
server[1:3]

每个主机组自定义 IP

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 -}}"
