连接错误：获取服务器 API 版本时出错：Ansible

Question

我是 Ansible 的新手。我已经按照 ansible PlayBook 运行并发现了这些错误：

---
- hosts: webservers
  remote_user: linx
  become: yes
  become_method: sudo
  tasks:

    - name: install docker-py
      pip: name=docker-py

    - name: Build Docker image from Dockerfile
      docker_image:
        name: web
        path: docker
        state: build

    - name: Running the container
      docker_container:
        image: web:latest
        path: docker
        state: running

    - name: Check if container is running
      shell: docker ps

错误信息：

失败的！=> {"changed": false, "msg": "错误连接：获取服务器 API 版本时出错：（'连接中止。'，错误（2，'没有这样的文件或目录'））”}

这是我的文件夹结构：

.
??? ansible.cfg
??? docker
?   ??? Dockerfile
??? hosts
??? main.retry
??? main.yml

我很困惑该docker文件夹已经在我的本地文件夹中，但不知道为什么我遇到了这些错误消息。

我发现解决方案是DockerdaemonDocker安装后无法正常工作Ansible。需要在我的游戏板中添加以下命令。

---
- hosts: webservers
  remote_user: ec2-user
  become: yes
  become_method: sudo
  tasks:
    - name: install docker
      yum: name=docker

    **- name: Ensure service is enabled
      command: service docker restart***

    - name: copying file to remote
      copy:
        src: ./docker
        dest: /home/ec2-user/docker
    - name: Build Docker image from Dockerfile
      docker_image:
        name: web
        path: /home/ec2-user/docker
        state: build
    - name: Running the container
      docker_container:
        image: web:latest
        name: web
    - name: Check if container is running
      shell: docker ps
