在特定主机组中的Ansible中检查wait_for不起作用 [英] Checking wait_for in Ansible in a particular host group does not work

问题描述

我有一本类似

  ---
  - name: testplaybook
  hosts:
  gather_facts: yes
  roles:
     -role: samplerole

角色:

 - name: checking for port open
   wait-for: 
      timeout: 3
      host: groups['git_groups']
      port: 7809
      ignore_error: yes
      register: port_check

对于上面的代码，主机: groups ['git_groups'] 在这里不能作为输入.当我运行剧本时，它将检查主机的整个列表，而不是特定的组.

For the above code the host: groups['git_groups'] doesn't work as an input here. When I run the playbook, it checks for the entire lists of hosts rather than that particular group.

推荐答案

您不能将任意数据结构(以您的情况为列表)提供给需要字符串的模块参数("

You cannot feed an arbitrary data structure (list in your case) to an argument of a module which requires a string ("A resolvable hostname or IP address to wait for").

您应该使用 with_items 循环:

You should use a with_items loop:

- name: checking for port open
  wait_for: 
    timeout: 3
    host: "{{ item }}"
    port: 7809
  ignore_error: yes
  register: port_check
  with_items: "{{ groups['git_groups'] }}"

^{您还有两个任务指令的缩进错误.}
