Kubernetes 不能'；t解决模块/操作'；k8s#U执行官'；关于Ansible剧本

我试图通过Ansible重新启动Rancher群集上的pod，但出现以下错误：

ERROR! couldn't resolve module/action 'k8s_exec'. This often indicates a misspelling,                                                                                                        missing collection, or incorrect module path.

The error appears to be in '/home/ansible/ansible/GetKubectlPods': line 27, column 7,                                                                                                        but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

    -
      name: Reboot Machine
      ^ here

我不知道为什么我会出错，因为我也在使用k8s_信息，他工作得很好

这是我正在运行的剧本：

--- 

- hosts: localhost
  connection: local
  remote_user: root

  vars:
    ansible_python_interpreter: '{{ ansible_playbook_python }}'

  tasks:
    -
      name: Get the pods in the specific namespace
      k8s_info:
        kubeconfig: '/etc/ansible/RCCloudConfig'
        kind: Pod
        namespace: redmine
      register: pod_list

    -
      name: Print pod names 
      debug:
         msg: "pod_list: {{ pod_list | json_query('resources[*].status.podIP')  }} "

    - set_fact:
        pod_names: "{{pod_list|json_query('resources[*].metadata.name')}}"
    -
      name: Reboot Machine
      k8s_exec:
        kubeconfig: '/etc/ansible/RCCloudConfig'
        namespace: redmine
        pod: redmine_quick-testing-6c57cc5d65-lwkww #pod name
        command: reboot

可翻译版本：

ansible 2.9.9
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/home/ansible/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.6/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 3.6.8 (default, Apr 16 2020, 01:36:27) [GCC 8.3.1 20191121 (Red Hat 8.3.1-5)]

如果我编辑剧本并添加

community.kubernetes集合

，则会出现以下错误：

解决方案：

找到您的

k8s_exec.py

文件，并从

Kubernetes.api

到

Kubernetes.api

日志

动词使用完全不同的协议我已经通过修改k8s_exec.py文件和更改API名称解决了上述问题。我现在最大的问题是，我无法使用k8s_exec命令对POD运行扩展命令。如果我给他一个“ls/opt”例如，由于命令的工作方式，我无法检索任何内容。有什么可能的解决方案吗？你能把你的解决方案贴在问题的答案上吗？回答的第二部分是另一个主题，因此应该作为单独的问题提问。如果没有更多细节，我们无法帮助您排除404故障，首先是

kubectl--kubeconfig/etc/ansible/RCCloudConfig-n redmine exec redmine\u quick-testing-6c57cc5d65-lwkww--ls-l

是否成功。
