Wechseln zu einer anderen Redis-Instanz?

Unterstützung Installation
1

Meine Discourse-Instanz nutzte zuvor eine gemeinsam genutzte Redis-Instanz mit anderen Anwendungen. Jetzt möchte ich, dass Discourse eine eigene Redis-Instanz verwendet. Kann ich einfach die YAML-Konfiguration bearbeiten, ein neues Image bootstrappen, den Container neu starten und feststellen, dass alles in Ordnung ist?

Beim Bootstrappen des neuen Images erhalte ich folgenden Fehler:

./discourse-doctor kann helfen, das Problem zu diagnostizieren.

Ich bin mir nicht sicher, ob es notwendig ist, Daten von der alten Redis-Instanz zu migrieren, damit es funktioniert.

2

Stellen Sie sicher, dass der Container auf diese IP zugreifen kann.

Das ist nicht erforderlich.

Es scheint, dass ein normaler Container (im Gegensatz zu Kubernetes-Pods) keine Verbindung zu einer Kubernetes-ClusterIP herstellen kann. Ich habe versucht, über redis-cli in einem Redis-Container eine Verbindung zu meiner neuen Redis-Instanz herzustellen, was jedoch fehlschlug. Allerdings kann ich eine Verbindung zur Redis-Instanz auf dem Host herstellen. Was ist der empfohlene Weg, um in einer Kubernetes-Umgebung zu arbeiten?

Wir bieten Standardmethoden an, um außerhalb des Anwendungscontainers auf Datenbanken zuzugreifen, wie unter Configure Discourse to use a separate PostgreSQL server beschrieben. Die Details zur Netzwerkkonfiguration bei diesen fortgeschrittenen Setups liegen in Ihrer Verantwortung, da sie je nach Ihrer Implementierung stark variieren können.

Wir bieten bereits eine extrem einfache Installation für alle unter discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub an, die funktioniert und Tausende von Instanzen im Internet betreibt. Ich befürchte jedoch, dass diejenigen, die sich für einen eigenen Weg entscheiden, mit den Konsequenzen leben müssen, da es für uns unmöglich ist, Support für alle möglichen Kombinationen anzubieten.

Für alle, die auf dasselbe Problem gestoßen sind: Ich habe es schließlich mit ./launcher bootstrap web_only --docker-args "--network=host" gelöst. Es scheint, dass ein k8s-Node-Host eine Verbindung zu einer ClusterIP herstellen kann, ein normaler Docker-Container (kein k8s-Pod) jedoch nicht.
