告诉Ansible剧本在远程主机上使用哪个版本的Python

Question

我有一个需要Python3.8或更高版本才能运行的Ansible模块。我们通过AWX部署我们的剧本(由另一个团队管理)。有没有一种方法可以让AWX运行特定版本的python，或者这是需要在AWX方面解决的问题?

我已经尝试将ansible_python_interpreter和interpreter_python添加到我的ansible.cfg中，添加为vars，并将其添加到模块中作为vars:

vars:
ansible_python_interpreter: /usr/bin/python3.9
interpreter_python: /usr/bin/python3.9
OR
import_role:
name: aviconfig
vars:
ansible_playbook_python: /usr/bin/python3.9
interpreter_python: /usr/bin/python3.9

但是当我在AWX中查看任务时，我得到以下错误:

fatal: [localhost]: FAILED! => {
"msg": "Unable to import vmware.alb.avi_serviceenginegroup due to more than 255 arguments"
}

在AWX GUI中，没有"执行环境"的下拉菜单;

参见INTERPRETER_PYTHON。引言:

用于在远程目标上执行模块的Python解释器的路径…

• ansible_python_interpreter是一个变量
• interpreter_python是ansible.cfg
中使用的配置键。

当你声明变量

vars:
ansible_python_interpreter: /usr/bin/python3.9
interpreter_python: /usr/bin/python3.9

模块将在远程主机上使用/usr/bin/python3.9。变量interpreter_python不影响任何东西。这可以在配置文件中使用。参见配置Ansible

shell> cat ansible.cfg
[defaults]
interpreter_python = /usr/bin/python3.9
...

一般来说，你可以为play、role、block和task声明变量。例如，为每个任务声明Python版本

shell> cat pb.yml
- hosts: test_14
tasks:
- ping:
vars:
ansible_python_interpreter: /usr/local/bin/python3.7
- ping:
vars:
ansible_python_interpreter: /usr/local/bin/python3.8
- ping:
vars:
ansible_python_interpreter: /usr/local/bin/python3.9

为

shell> ansible-playbook pb.yml -vvv | grep /usr/local/bin/python
