Kann nicht von Python mit Docker Containers Elastic Search und MongoDB herstellen [geschlossen] ⇐ Python

[Anonymous]

Ich habe diesen Code, der die Benutzerabfrage an Kafka sendet, zusammen mit Dokumenten, die aus dem elastischen Suchcontainer- und Geschäftsregeln vom MongoDB -Container zurückgegeben wurden. Das Problem ist jedoch, dass Dokumente nicht von Mongo und elastischer Suchverbindung abgerufen werden.

Code: Select all
