Ansible Docker連接錯誤

Question

我正在運行正式版本1.9，docker-py version 1.1.0和Docker 1.9.1。我有一個私人的不安全碼頭註冊表，運行在http://registry.myserver.com:5000。

我有一個ansible任務使用此遠程註冊表一把拉住圖像啓動容器：

--- 
    - name: Start User Service Container 
    docker: 
     name: userService 
     image: user-service 
     registry: registry.myserver.com:5000 
     state: running 
     insecure_registry: yes 
     expose: 
      - 8355 

然而，這是目前返回以下錯誤：

failed: [bniapp1] => {"changed": false, "failed": true} msg: ConnectionError(ProtocolError('Connection aborted.', error(2, 'No such file or directory')),)

詳細輸出：

注意：當我在遠程服務器上手動運行容器時，th e圖像被拉出，容器正確啓動：

docker run registry.myserver.com:5000/user-service 

Answer 1

我得到這個錯誤，因爲我的碼頭守護程序沒有運行。在啓動碼頭服務器之前添加以下安全代碼：

# Start Docker Service 
- name: Start Docker service 
    service: name=docker state=started 
    become: yes 
    become_method: sudo 
- name: Boot Docker on startup 
    service: name=docker enabled=yes 
    become: yes 
    become_method: sudo
