IBM Cloud Functions：如何运行Docker函数？

Question

FROM python:3.7
COPY ./src /data/python
WORKDIR /data/python
RUN pip install --no-cache-dir flask
EXPOSE 8080
CMD ["python", "main.py"]

• main.py

import os
from flask import Flask
app = Flask(__name__)

@app.route('/')
def index():
    return {'body': os.environ.items()}


def run():
    app.run(host='0.0.0.0', port=8080)


if __name__ == '__main__':
    run()

click invoke result

[
  "2021-01-29T09:53:30.727847Z    stdout: * Serving Flask app \"main\" (lazy loading)",
  "2021-01-29T09:53:30.727905Z    stdout: * Environment: production",

  "2021-01-29T09:53:30.747035Z    stderr: 172.30.139.167 - - [29/Jan/2021 09:53:30] \"\u001b[33mPOST /init HTTP/1.1\u001b[0m\" 404 -",
  "2021-01-29T09:53:30.748Z       stderr: The action did not initialize or run as expected. Log data might be missing."
]

I've added the Docker container to IBM Cloud Functions

What would be the best way to approach this?
