Le client a envoyé une requête HTTP à un serveur HTTPS

J'ai une application python exécutée sur une machine virtuelle, c'était un héritage, et maintenant je migre vers un Kubernetes.

J'utilise le package influxdb==5.2.3, En me connectant à ce formulaire Influx(Host=r'influx_Host', port=8086, username='MY_USER', password='***', database='DB_NAME', ssl=True). Ce python script appelle un InfluxBD en utilisant un certificat SSL et lorsque je l'exécute directement en utilisant python app.py Fonctionne bien, mais le problème est quand:

J'ai dockerized le script me montre l'erreur suivante.

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)
  File "/usr/src/app/analitica_py_lib_conexiones/conexion_influx.py", line 82, in multiple_query_to_df
    resultado = self.__cliente.query(";".join(queries))
  File "/usr/local/lib/python3.8/site-packages/influxdb/client.py", line 445, in query
    response = self.request(
  File "/usr/local/lib/python3.8/site-packages/influxdb/client.py", line 302, in request
    raise InfluxDBClientError(response.content, response.status_code)
influxdb.exceptions.InfluxDBClientError: 400: Client sent an HTTP request to an HTTPS server.

Je comprends que, de l'intérieur du conteneur, le script utilise https pour appeler Influx, mais je pense que la connexion est redirigée à l'extérieur du conteneur en utilisant Http et perd toute configuration SSL, pourquoi? Je ne sais pas.

J'ai testé déployé sur Kubernetes

J'ai essayé de déployer sur Kubernetes en pensant que j'obtenais la même erreur, mais cela a changé.

Je ne sais pas si cela est lié à l'erreur précédente.

J'obtiens la même erreur que j'ai sur Kubernetes, mais en exécutant le script localement, je change la valeur SSL de True à False dans l'appel de service Influx(Host=r'influx_Host', port=8086, username='MY_USER', password='***', database='DB_NAME', ssl=False).

Cela semble un problème de réseau. J'ai rencontré un problème plus simple pour me connecter à MongoDB à cause de Proxy. Tout peut se produire ce problème.

Par défaut, chaque conteneur exécuté par Docker possède son propre espace de noms réseau.

Offrant quelques méthodes de solution:

  1. traceroute <cluster-ip> exécutez cette commande et vérifiez si vous arrivez au cluster à l'intérieur du conteneur d'attachement de conteneur et exécutez la commande docker exec -it container /bin/bash.
  2. Vérifiez le proxy. export vérifier les variables d'environnement liées au proxy.
  3. curl www.google.com
  4. Essayez de connecter d'autres éléments dans le cluster. Par exemple MySQL, etc. (Une fois qu'une machine m'écrit automatiquement sur la liste noire, j'ai essayé de résoudre le problème de connexion 2 jours)
  5. Essayez d'utiliser une image python-slim. l'image mince est basée sur ubuntu.

C'est un très bon document pour comprendre et résoudre le problème de connexion docker.
