У меня python приложение, работающее на виртуальной машине, было устаревшим, и теперь я перехожу на Kubernetes.
Я использую пакет influxdb==5.2.3, подключаясь к этой форме Influx(host=r'influx_HOST', port=8086, username='MY_USER', password='***', database='DB_NAME', ssl=True). Этот сценарий python вызывает InfluxBD с использованием SSL-сертификата, и когда я запускаю напрямую с использованием python app.py, он работает хорошо, но проблема заключается в том, что:
Я докертизировал скрипт, показывая мне следующую ошибку.
Traceback (most recent call last):
File "app.py", line 591, in <module>
get_horas_stock()
File "app.py", line 513, in get_horas_stock
df_temp = influx_temperatura.multiple_query_to_df(queries_temperatura)

resultado = self.__cliente.query(";".join(queries))

response = self.request(

raise InfluxDBClientError(response.content, response.status_code)
influxdb.exceptions.InfluxDBClientError: 400: Client sent an HTTP request to an HTTPS server.
Я понимаю, что изнутри контейнера скрипт использует https для вызова Influx, но я думаю, что соединение перенаправляется за пределы контейнера через Http и теряет всю конфигурацию SSL, почему? Я не знаю.
Я тестировал развернутые в Kubernetes
Я пытался развернуть в Kubernetes, думая, что я получаю ту же ошибку, но она изменилась.

Я получаю ту же ошибку, что и на Kubernetes, но при локальном запуске сценария я меняю значение SSL с True на False в службе Звоните Influx(host=r'influx_HOST', port=8086, username='MY_USER', password='***', database='DB_NAME', ssl=False).
