クライアントがHTTPSリクエストをHTTPSサーバーに送信しました

pythonアプリケーションが仮想マシンで実行されており、レガシーでしたが、今はKubernetesに移行しています。

私は_influxdb==5.2.3_パッケージを使用して、このフォームInflux(Host=r'influx_Host', port=8086, username='MY_USER', password='***', database='DB_NAME', ssl=True)に接続します。このpythonスクリプトは、SSL証明書を使用してInfluxBDを呼び出し、_python app.py_を使用して直接実行するとうまくいきますが、問題は次の場合です:

スクリプトをドッキングすると、次のエラーが表示されます。

_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))

    raise InfluxDBClientError(response.content, response.status_code)
influxdb.exceptions.InfluxDBClientError: 400: Client sent an HTTP request to an HTTPS server.
_

コンテナー内からスクリプトがhttpsを使用してInfluxを呼び出すことを理解していますが、接続はHttpを使用してコンテナー外にリダイレクトされ、すべてのSSL構成が失われると思います。なぜですか?知りません。

私はKubernetesにデプロイしてテストしました

同じエラーが発生すると思ってKubernetesにデプロイしようとしましたが、変更されました。

以前のエラーに関連しているかどうかはわかりません。

Kubernetesで発生したのと同じエラーが発生しますが、スクリプトをローカルで実行して、サービス呼び出しInflux(Host=r'influx_Host', port=8086, username='MY_USER', password='***', database='DB_NAME', ssl=False)でSSL値をTrueからFalseに変更します。

ネットワークに問題があるようです。プロキシのため、MongoDBに接続するときに問題が発生しました。この問題はすべて発生する可能性があります。

デフォルトでは、Dockerによって実行される各コンテナーには、独自のネットワーク名前空間があります。

いくつかのソリューションメソッドの提供:

  1. traceroute <cluster-ip>このコマンドを実行し、コンテナー接続コンテナー内のクラスターに到着するかどうかを確認し、docker exec -it container /bin/bashコマンドを実行します。
  2. プロキシを確認します。 exportプロキシに関連する環境変数を確認します。
  3. curl www.google.com
  4. クラスター内の別のものを接続してみてください。たとえば、MySQLなど(マシンがブラックリストを自動的に書き込んだら、接続の問題を2日間解決しようとしました)
  5. Python-slimイメージを使用してみてください。スリムなイメージは、ubuntuに基づいています。

Docker接続の問題を理解して解決するための非常に優れたドキュメントです。
