Windows Server 2012 R2 and AWS S3 Download from Ansible

问题

I'm trying to download some files from AWS S3 with IAM Role for EC2 but Ansible is getting an error. Other Ansible win_* modules works great.

Windows Server has Python2 and Python3, and also boto and boto3 modules. Cmd is responding to python command. It opens Python3 when it is executed. I also tested the 'import boto' command when the Python3 is opened to be sure that module is installed.

Ansible Playbook is configured like:

- name: test s3 module
  hosts: windows
  tasks:
    - name: get s3 file
      aws_s3:
        bucket: drktests3
        object: /test
        dest: C:\tests3.txt
        mode: get

When i run this configuration, the output is like that:

root@ip-172-31-22-4:/etc/ansible/playbooks# ansible-playbook s3test

PLAY [test s3 module] *******************************************************************************************************************************************

The same script works on the Master server(Linux Ubuntu) if i change the hosts value to localhost. Why Ansible cannot execute the python code on the Windows server?

回答1:

I found that there is a section about the problem in Ansible Docs.

Can I run Python modules? No, the WinRM connection protocol is set to use PowerShell modules, so Python modules will not work. A way to bypass this issue to use delegate_to: localhost to run a Python module on the Ansible controller. This is useful if during a playbook, an external service needs to be contacted and there is no equivalent Windows module available.

So if you want to do such a process, you have to workaround the problem.

I solved it with suggestion that Ansible Documentation gives.

- name: test s3 module
  hosts: windows
  tasks:
    - name: get s3 file
      aws_s3:
        bucket: bucketname
        object: /filename.jpg
        dest: /etc/ansible/playbooks/test.jpg
        mode: get
      delegate_to: localhost

    - name: copy to win server
      win_copy:
        src: /etc/ansible/playbooks/test.jpg
        dest: C:/test.jpg

When you use these sample codes, firstly you are downloading the files to Master Ansible server with delegate_to. And after then that you are copying the files to Windows host.
