使用ansible docker模块 踩过的坑
原因分析：
还是着急用了，没有首先去看官方的第一手文档
报错信息：

解决办法：
官方文档
For Python 2.7, you need to use a version between 2.0.0 and 4.4.4 since the Python package for Docker removed support for Python 2.7 on 5.0.0. You can install the specific version of the Docker SDK for Python as follows:
$ pip install 'docker==4.4.4'
实际过程:
因为我这里是的使用场景是用在项目现场的，所以无法连接互联网，所以打算通过离线方式安装上面的docker模块，然后这里就是各种环境问题，我这里先是用本地环境测试的，本地做好了才方便做成roles方案直接调用，现在说说自己踩过的坑或走的弯路吧。
1.环境信息
# yum 源使用的是本地内网搭建的，现场也是如此
$ cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
$ ssh -V
OpenSSH_8.8p1, OpenSSL 1.1.1l 24 Aug 2021
$ ansible --version
ansible 2.9.25
$ python --version
Python 2.7.5
2.错误的思路
# 先学下模块用法
$ ansible-doc -l|grep docker
# 直接测试登录模块
$ cat test.yaml
---
- name: test module docker_login
hosts: localhost
tasks:
- name: Log into private registry and force re-authorization
docker_login:
registry: harbor.dockerregistry.com
username: admin
password: Harbor12345
reauthorize: yes
# 然后就有了此文档开篇的那个报错
# 然后各种博客帖子里查，现在回想这里是在干蠢事，无用功。按照别人博客的意思将docker与requests两个模块装了，然后还是各种报错，这时候报的是语法错误。
# 后面偶然查到了官方文档对这个模块的介绍的一开始的地方。
3.离线过程
这里沿着上面官方给的版本要求给docker-py对应4.4.4装了，不过我这里要走离线模式。
3.1 下载源码
https://github.com/docker/docker-py/releases/tag/4.4.4
3.2 查看依赖
$ cat docker-py-4.4.4/requirements.txt
appdirs==1.4.3
asn1crypto==0.22.0
backports.ssl-match-hostname==3.5.0.1
cffi==1.14.4
cryptography==3.2
enum34==1.1.6
idna==2.5
ipaddress==1.0.18
packaging==16.8
paramiko==2.4.2
pycparser==2.17
pyOpenSSL==18.0.0
pyparsing==2.2.0
pywin32==227; sys_platform == 'win32'
requests==2.20.0
six==1.10.0
urllib3==1.24.3
websocket-client==0.56.0
3.3 实际的依赖
上面模块给的是一种依赖，实际操作又是另一种，若哪位朋友使用有缘使用我这份文档也仍有可能存在这个问题，不过整体来讲，我这环境还算清爽，基本没装什么，估计问题也不大
