Ansible - 按照我的意愿与主机一起玩 [英] Ansible - Play with hosts in order I desire

问题描述

当运行剧本时，Ansible 随机将节点设置为第一、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 以确保它按排序顺序与主机一起执行?示例:

How can I configure Ansible to ensure it executes with the hosts in sorted order? Example:

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

Serial: 1 不是一个选项，因为它会减慢播放速度，而且我的剧本适用于单次播放中的 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:

这是现在的默认行为，ansible 将按照 inventory 文件中提到的 order 播放主机.Ansible 还提供了一些内置方式，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 可能的值是:

• 库存:默认值.订单是由库存提供"
• reverse_inventory:顾名思义，这颠倒了库存按提供"的顺序
• sorted:主机按名称的字母顺序排序
• reverse_sorted:主机按名称按字母逆序排序
• shuffle:每次运行时主机随机排序
