无法在Docker中构build图像

当试图构build图像，我得到下面的错误。 我也在添加相关的项目文件。

• Dockerfile
• 泊坞窗，compose.yml
• init .py
• manage.py

错误：

Building users-service Step 1/7 : FROM python:3.6.1 ERROR: Service 'users-service' failed to build: Get https://registry-1.docker.io/v2/: dial tcp 52.206.156.207:443: getsockopt: connection refused 

这是我的Dockerfile

 FROM python:3.6.1 RUN mkdir -p /usr/src/app WORKDIR /usr/src/app ADD ./requirements.txt /usr/src/app/requirements.txt RUN pip install -r requirements.txt ADD . /usr/src/app CMD python manage.py runserver -h 0.0.0.0 

这是docker-compose.yml

 version: '2.1' services: users-service: container_name: users-service build: . volumes: - '.:/usr/src/app' ports: - 5001:5000 # expose ports - HOST:CONTAINER 

init .py

 from flask import Flask, jsonify # instantiate the app app = Flask(__name__) # set config app.config.from_object('project.config.DevelopmentConfig') @app.route('/ping', methods=['GET']) def ping_pong(): return jsonify({'status': 'success', 'message': "pong"}) 

manage.py

 from flask_script import Manager from project import app # configure your app manager = Manager(app) if __name__ == '__main__': manager.run()
