无法使用 ansible playbook 安装 dnspython

Question

团队，

我的剧本如下，我也尝试过 become: yes 但没有成功。如何解决这个问题？

      - easy_install:
          name: dnspython
          state: present
        #become: yes

      - name: Validate DNS record lookup for {{ kubeapi_server }}
        debug: msg="{{ lookup('dig', '{{ kubeapi_server }}' )}}"
        vars:
          variable: "{{ lookup('dig', '{{ kubeapi_server }}' )}}"
        failed_when: not variable

输出：

Answer 1

你的问题很简单。

16:18:07  [0;31m    "msg": "Failed to find required executable easy_install in paths: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"[0m

日志清楚地表明无法在您尝试安装 dnspython 的主机上找到 easy_install。

您可以通过安装 python-setuptools 在您的远程主机上安装 easy_install。

仅供参考， easy_install 是一个 Python 模块，作为 Python setuptools 的一部分提供，因此安装 setuptools 会自动安装 easy_install。

我添加了示例任务（@Matthew 也建议），可以帮助您，

- apt:
    name: python-setuptools
    state: present

- easy_install:
    name: dnspython
    state: present
