Ansible剧本模块get_url

如何解决Ansible剧本模块get_url

运行我的剧本以检索URL时，出现以下错误：

fatal: [srwdvkubnode1]: Failed! => {"changed": false,"dest": "/etc/yum.repos.d/docker-ce.repo","elapsed": 0,"msg": "Request Failed: <urlopen error [Errno -2] Nom ou service inconnu>","url": "https://download.docker.com/linux/centos/docker-ce.repo"}
fatal: [srwdvkubnode2]: Failed! => {"changed": false,"url": "https://download.docker.com/linux/centos/docker-ce.repo"}

它是法语，但这意味着：未知名称或服务！
我不明白为什么。
这是我的剧本：

---
- name: Install docker
  hosts: docker

  tasks:
    - name: Add Docker repo
      get_url:
        url: https://download.docker.com/linux/centos/docker-ce.repo
        dest: /etc/yum.repos.d/docker-ce.repo
      become: yes
