Ansible-按我的意愿与主持人一起玩 [英] Ansible - Play with hosts in order I desire

问题描述

运行剧本时，Ansible会随机将一个节点设置为第一，第二和第三.

When running a playbook Ansible randomly sets a node as first, second and third.

TASK [setup] ********
ok: [node-p02]
ok: [node-p03]
ok: [node-p01]

如何配置Ansible以确保其发挥作用:

How can I configure Ansible to ensure it plays as:

TASK [setup] ********
ok: [node-p01]
ok: [node-p02]
ok: [node-p03]

Serial: 1是不可选项，因为它会减慢播放速度，而我的剧本只能在一次播放中用于3个节点.

Serial: 1 is not an option, since it slows down the play, and my playbook is meant for 3 nodes in a single play.

推荐答案

适用于Ansible 2.4及更高版本:

这是默认的行为，ansible将按文件中提到的顺序播放主机. Ansible还提供了一些内置的方式，您可以使用order来控制它:

Applicable for Ansible 2.4 and higher:

This is now the default behaviour, ansible will play the hosts in the order they were mentioned in the inventory file. Ansible also provides a few built in ways you can control it with order:

- hosts: all
  order: sorted
  gather_facts: False
  tasks:
    - debug:
        var: inventory_hostname

order的可能值为:

• 库存:默认值.订单是按库存提供的"
• reverse_inventory:顾名思义，这将颠倒广告资源按提供的顺序"
• 已排序:主机按名称的字母顺序
• reverse_sorted:主机按名称以相反的字母顺序排序
• 随机播放:主机在每次运行时都是随机排序的
