我正在尝试获取Flask Docker容器的健康状态。这个容器没有暴露端口5000，它与wsgi服务器对话，然后我使用Nginx作为Flask的套接字代理。Flask容器正在运行Flask和uwsgi。我能够在Nginx上进行健康检查，但不是在Flask容器上。每次我检查健康状态时，Flask容器都显示为不健康。虽然它显示为不健康，但站点和API功能齐全。这是在一个开发环境的时刻.我已经尝试了只是localhost和localhost：5000上的portcheck和似乎没有为我工作，都返回不健康.不知道我做错了什么.
uwsgi.ini:

[uwsgi]

module = wsgi:app
master = true
processes = 5
enable-threads = true
single-interpreter = true

buffer-size = 32768

socket= api.sock
chmod-socket = 664
uid = www-data
gid = www-data

wsgi.py

from flask_project import create_app

app = create_app()

if __name__ == '__main__':
    app.run(debug=True)

init.py

from flask import Flask

def create_app():
    app = Flask(__name__)

    ## internal configs here
    
    return app
