linux - 为什么ansible远程副本不能从本地工作

问题描述

我刚开始学习 ansible 并编写第一个copy模块，但我不知道为什么它不起作用。

---
 - hosts: osa
   tasks:
     - name: Copying file to remote host
       copy: src=/tmp/foo.txt dest=/tmp/bar.txt

运行剧本，但什么也没发生，也没有错误。

# /usr/bin/ansible-playbook /home/spatel/ansible/first-playbook.yml

PLAY [osa] **************************************************************************************************************************************************************************

TASK [Gathering Facts] **************************************************************************************************************************************************************
ok: [10.5.1.160]

TASK [Copying file to remote host] **************************************************************************************************************************************************
ok: [10.5.1.160]

PLAY RECAP **************************************************************************************************************************************************************************
10.5.1.160                 : ok=2    changed=0    unreachable=0    failed=0

我的 /etc/ansible/hosts 文件有远程主机 IP 地址：

[osa]
10.5.1.160

详细输出：

# ansible-playbook -vv first-playbook.yml
ansible-playbook 2.4.1.0

更新

我注意到它将文件复制到本地主机而不是远程主机，这没有任何意义，为什么它在输出中说它正在远程主机（10.5.1.160）上执行剧本？？？？？？

# ls -l /tmp/bar.txt
-rw-r--r--. 1 root root 16 May 24 10:45 /tmp/bar.txt

解决方案

我有一个类似的问题，它正在远程服务器上查找文件。您正在远程服务器上运行任务，hosts: osa但文件位于本地主机上。我可以用delegate_to: localhost解决它。

---
 - hosts: osa
   tasks:
     - name: Copying file to remote host
       delegate_to: localhost
       copy: src=/tmp/foo.txt dest=/tmp/bar.txt

但是，我什至必须首先从 localhost 获取文件，然后再将其提供给远程主机：

  - name: read files

    # This needs to run on localhost, because that's where
    # the keys are stored.
    delegate_to: localhost

    command: cat {{item}}

    # Register the results of this task in a variable called
    # "files"
    register: files

    with_fileglob:
      - "/tmp/*.txt"

  - name: show what was stored in the files variable
    debug:
      var: files

  - name: Copying file to remote host
     delegate_to: localhost
     copy: src="{{item.stdout}}" dest=/tmp/bar.txt
    with_items: "{{keys.results}}"
