Ansible playbook 循环控制流 [英] Ansible playbook looping control flow

问题描述

我有一本手册，可以检查 6 个 jenkins 服务器的已安装插件列表.

I have a playbook that checks the list of installed plugins for 6 jenkins servers.

这是主机文件:

[masters]
server1
server2
server3
server4
server5
server6

这是剧本中处理获取已安装插件列表的任务:

Here is the task within the playbook that handles obtaining the list of installed plugins:

 - name: Obtaining a list of Jenkins Plugins
   jenkins_script:
     script: 'println(Jenkins.instance.pluginManager.plugins)'
     url: "{{ item }}"
     user: 'admin'
     password: 'password'
   with_items:
     - 'url1'
     - 'url2'
     - 'url3'
     - 'url4'
     - 'url5'
     - 'url6'

这运行得非常好，但打印出 36 个已安装插件的列表，而不仅仅是 6 个.似乎该剧本正在为每个主机插入每个 url，但是我对 ansible 还很陌生，所以有人知道如何解决这个问题?

This runs perfectly fine, but prints out 36 lists of installed plugins rather than just 6. It appears that the playbook is plugging every url in for each of the hosts, however I'm fairly new to ansible, so does anyone know how to get around this issue?

推荐答案

如果您有六个名为 server1-server6 的 Jenkins 服务器，则不需要进行循环.只需触发 jenkins_script 任务并设置 hosts 模式以在每个服务器上运行此任务:

If you have six Jenkins servers named server1-server6, you don't need to make a loop. Just fire jenkins_script task and set hosts pattern to run this task on every server:

---
- hosts: server*
  tasks:
    - name: Obtaining a list of Jenkins Plugins
      jenkins_script:
        script: 'println(Jenkins.instance.pluginManager.plugins)'
        url: 'http://{{ inventory_hostname }}:8080/'
        user: 'admin'
        password: 'password'

这将在每台服务器上执行一次任务.

This will execute the task on every server once.
