Docker -Compose -Fehler beim Erstellen von Django Dockerfile: Fehler -2 Anschluss an Redis: 6379. Name oder Dienst nicht ⇐ Python

[Anonymous]

Ich versuche, eine Open-Source-Status-Seitenanwendung mit dem Repository von Status-Page/Status-Page mit Docker Compose einzurichten. Wenn ich Docker -compose -D -D -D -D -Dockerfile beim Build -Prozess des Django -Dienstes auf einen Fehler mache. Der Fehler scheint bei der Aktualisierung und initialisieren Sie die Anwendung, aber ich bin mir nicht sicher, wie ich sie weiter debuggen oder auflösen soll.# Use the official Python runtime image
