檔案傳輸 - copy 模組

1. Ansible 可以用並行的方式同時 scp 大量的檔案到多台主機，完整文件可用 ansible-doc 查詢 copy 模組文件。

   ceuser@deyu:~/ansible_pb$ ansible-doc copy | grep -A8 ^EX
   EXAMPLES:
   
   - name: Copy file with owner and permissions
     ansible.builtin.copy:
       src: /srv/myfiles/foo.conf
       dest: /etc/foo.conf
       owner: foo
       group: foo
       mode: '0644'
   

2. 先編輯一個測試檔 adhoc.txt

   ceuser@deyu:~/ansible_pb$ echo 'ad-hoc file transfer' > adhoc.txt
   ceuser@deyu:~/ansible_pb$ cat adhoc.txt
   ad-hoc file transfer
   

3. 使用 copy 模組將 adhoc.txt 複製到 dev 群組裡所有主機的 /home/ceuser 目錄:

   ceuser@deyu:~/ansible_pb$ ansible dev -m copy -a "src=adhoc.txt dest=/home/ceuser/"

       "src": "/root/.ansible/tmp/ansible-tmp-1770260586.953098-81322-277034741284408/source",
       "state": "file",
       "uid": 0
   }
   

4. 使用 shell 模組查看 dev 群組裡所有主機，有複製過來的檔案 adhoc.txt，由於 ansible.cfg 設定遠端用戶為 root，所以擁有者及群組皆為 root。

   ceuser@deyu:~/ansible_pb$ ansible dev -m shell -a "ls -l /home/ceuser/"
