Ansible K8s 模块:无法在 Python/usr/bin/python3 上导入所需的 Python 库 (openshift)

问题描述

环境

Ansible 2.9.6 (python3)

尝试运行一个简单的剧本

Tried to run a simple playbook

- hosts: master
  gather_facts: no
  become: yes
  tasks:
    - name: create name space
      k8s:
        name: testing
        api_version: v1
        kind: Namespace
        state: present

出现以下错误

}

这让我很困惑，

• 根本原因是没有名为 kubernetes 的模块"?
• 或无法在 Python/usr/bin/python3 上导入所需的 Python 库 (openshift)"?

如何解决这个问题?

任何帮助将不胜感激！

顺便说一句，

Kubernetes 主节点有/usr/bin/python3

推荐答案

查看这里的文档:https://docs.ansible.com/ansible/latest/modules/k8s_module.html

似乎您需要:

• python >= 2.7
• openshift >= 0.6
• PyYAML >= 3.11

一种方法是:

pip install openshift pyyaml kubernetes

旁注，我在这里添加了 kubernetes，但我相信它是 openshift 的依赖项.

Side note, I've added kubernetes here but I believe it's a dependency of openshift.

我们也可以这样做:

pip3 install openshift pyyaml kubernetes --user
