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

问题描述

我有一本剧本，检查了6台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

这是剧本中的任务，用于获取已安装插件的列表:

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'

这运行得很好，但是会打印出36个已安装插件的列表，而不仅仅是6个.看来，剧本正在为每个主机插入每个url，但是我对ansible还是陌生的，所以有人知道吗如何解决这个问题?

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，则无需进行循环.只需触发jenkins_script任务并设置hosts模式即可在每台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'

这将在每个服务器上执行一次任务.

This will execute the task on every server once.
