Question

将应用程序部署到Google AppEngine后，从远程服务器启动我的应用程序遇到了很多麻烦。我查找了类似的问题，并尝试应用建议的修复程序，但仍然没有成功-我不断收到502 Bad Gateway Issue。有人可以建议吗？

文件夹结构如下：

目录：cross_sell_dash /
  app.yml
  database.py
  Dockerfile
  gcp-sa-creds.json
  main.py
  requirements.txt

app.yml

entrypoint: "gunicorn --bind:$PORT main:app"
env: flex
runtime: custom

main.py

app = Flask(__name__)

@app.route("/call/<function_name>/search/", methods=["GET"])
def callFunction(function_name: str):
    user_id = request.args.get('user_id')
    savm_id = request.args.get('savm_id')
    business_sub_entity = request.args.get('business_sub_entity')
    user_comments = request.args.get('user_comments')
    user_approval = request.args.get('user_approval')
    functionToCall = getattr(Database(), function_name)
    return str(functionToCall(user_id, savm_id, business_sub_entity, user_comments, user_approval))

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=8080, debug=True)

Dockerfile

FROM python:3-onbuild

RUN mkdir /app
ADD . /app

WORKDIR /app

RUN pip3 --no-cache-dir install -r requirements.txt

EXPOSE 8080

ENTRYPOINT ["python3", "main.py"]
ENTRYPOINT ["gunicorn","--bind=0.0.0.0:8080","main:app"]

删除app.yaml中的entrypoint
如下更新Dockerfile

FROM python:3-onbuild

RUN mkdir /app
ADD . /app

WORKDIR /app

RUN pip3 --no-cache-dir install -r requirements.txt

EXPOSE 8080

ENTRYPOINT ["gunicorn", "--bind=0.0.0.0:8080", "main:app"]
