ansible - 在 ansible 任务中使用的 delegate_to 问题

Question

这是使用“ delegate_to: "localhost"”的任务尝试 ssh“localhost”而不是从“localhost”（ansible master）到远程的 ssh 端口的正确行为吗？

剧本失败：

"Timeout when waiting for localhost:2022"

这里的示例配置我复制它：

库存文件：

[testremote]
192.168.170.113 ansible_user=ja

Ansible 配置文件：

[defaults]
host_key_checking = False
inventory = hosts
callback_enabled = profile_tasks
ansible_port = 2022

剧本文件：

- hosts: testremote
  gather_facts: false
  vars:
    desired_port: 2022
  tasks:
    - name: check if ssh is running on {{ desired_port }}
      delegate_to: localhost
      wait_for:
        port: "{{ desired_port }}"
        host: "{{ ansible_host }}"
        timeout: 10
      ignore_errors: true
      register: desired_port_check

    - when: desired_port_check is success
      block:
        - debug:
            msg: "ssh is running on desired port"

        - name: configure ansible to use port {{ desired_port }}
          set_fact:
            ansible_port: "{{ desired_port }}"

    - name: run a command on the target host
      command: uptime
      register: uptime

    - debug:
        msg: "{{ uptime.stdout }}"

远程主机已经可以在所需的端口上访问：

[ansible]$ ssh -p 2022 ja@testremote date
Sun Jun 20 16:40:36 CEST 2021
[ansible]$ ping testremote
PING testremote (192.168.170.113) 56(84) bytes of data.
64 bytes from testremote (192.168.170.113): icmp_seq=1 ttl=63 time=1.14 ms

运行剧本时的结果：

[ansible]$ ansible-playbook test_playbook.yml
