python - 使用 Docker 在 Flask 中部署 SpaCY 应用程序
问题描述
我有一个用 Python Flask 编写的 SpaCY 应用程序来检测命名实体，该实体将用作与另一个应用程序一起使用的服务。它是使用 Visual Studio 作为 Python 应用程序创建的，虚拟环境是 Python 版本 (3.6)。我将它作为 Windows VM 部署在 Azure 上，效果很好。
下一步是使用 Docker 进行部署。我创建了一个 Dockerfile，构建了一个镜像并运行了它。它确实运行并显示了 url 和端口。但是在访问任何已定义的路线时，我会收到“无法访问此站点”。
我能够直接运行 python 项目或通过 Visual Studio 并且没有任何问题，这让我相信问题出在我的 Dockerfile 或我对它的理解上。
作为指导，我开始遵循 Microsoft 的 Azure 教程（https://docs.microsoft.com/en-us/azure/container-instances/container-instances-tutorial-prepare-app）并使用示例项目：https:// github.com/Azure-Samples/aci-helloworld我能够构建一个 dockerfile 并访问它的路由。
现在它让我相信 SpaCY、我的 dockerfile 或 SpaCY 和 Docker 之间的某些不兼容导致了这种情况。对此的任何帮助将不胜感激。如果我遗漏任何信息，我很乐意补充。
我的项目结构：
- SpaCY解析器
- 环境
- runserver.py（这将启动服务器）
- SpaCY解析器
- 初始化.py
- 解析器.py
运行服务器.py
from SpaCYParser import app
if __name__ == '__main__':
app.run()
初始化.py
from flask import Flask
app = Flask(__name__)
解析器.py
from flask import request, jsonify, make_response
from SpaCYParser import app
import json, spacy
from SpaCYParser import parserOutput
from SpaCYParser import Entity
from SpaCYParser import NEREntities
@app.route('/')
@app.route('/test')
def ping():
print("hello world")
return "HELLO WORLD"
@app.route('/parse')
def parse():
# NER Specific code.

附加背景：我有一些学校项目的 Python 经验。这是我第一个使用和部署 Docker 的实例。当我们决定为不同的域（美国和加拿大，由于数据的敏感性）部署我们的项目并构建可用于轻松生成实例（容器？）的 docker 映像时，对 Docker 的需求就出现了。
