我有简单的应用程序 Package 在容器中
app = Flask(__name__)
@app.route('/readiness')
@app.route('/liveness')
def health():
return {"health_status": "running"}, 200
class StandaloneApplication(gunicorn.app.base.BaseApplication):
def __init__(self, flask_app, gunicorn_options=None):
self.options = gunicorn_options or {}
self.gunicorn_app = flask_app
super().__init__()
def load_config(self):
config = {key: value for key, value in self.options.items()
if key in self.cfg.settings and value is not None}
for key, value in config.items():
self.cfg.set(key.lower(), value)
def load(self):
return self.gunicorn_app
if __name__ == "__main__":
options = {
'bind': ['0.0.0.0:8080', '0.0.0.0:8090'],
'workers': 1,
"timeout": 60
}
StandaloneApplication(app, options).run()
log.info("Server started")已成功运行应用程序的容器

url = '0.0.0.0:8080/readiness'
requests.get(url)我得到了requests.exceptions.ConnectionError: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))
如何在Docker中正确请求 flask 应用程序？

您需要发布8080端口。当前，您有
8080/tcp, 0.0.0.0:8080->80/tcp，但此配置是the 8080 port inside the container is published on port 80 from local machine。您需要
8080/tcp, 0.0.0.0:8080->8080/tcp（与8090相同），将-p 8080:8080添加到docker运行命令，并使用docker ps进行检查。另一个细节，你可以使用localhost或者127.0.0.1来获取，0.0.0.0不推荐使用www.example.com。
