So löschen Sie alte Protokolle, die im sf-logs-Bucket gespeichert sind

Ein Fehler kann dazu führen, dass sich Protokolle im Objektspeicher-Bucket sf-logs ansammeln. Um alte Protokolle im Bucket sf-logs zu bereinigen, befolgen Sie die Anweisungen zum Ausführen des dedizierten Skripts. Stellen Sie sicher, dass Sie die für Ihren Umgebungstyp relevanten Schritte ausführen.
Führen Sie die folgenden Schritte aus, um alte Protokolle zu bereinigen, die im sf-logs -Bucket gespeichert sind:
  1. Rufen Sie die Version des sf-k8-utils-rhel -Images ab, die in Ihrer Umgebung verfügbar ist:
    • Führen Sie in einer Offlineumgebung den folgenden Befehl aus: podman search localhost:30071/uipath/sf-k8-utils-rhel --tls-verify=false --list-tags
    • führen Sie in einer Online-Umgebung den folgenden Befehl aus: podman search registry.uipath.com/uipath/sf-k8-utils-rhel --list-tags
  2. Aktualisieren Sie Zeile 121 in der folgenden yaml -Definition entsprechend, um das richtige Image-Tag einzuschließen:

  3. Kopieren Sie den Inhalt der oben genannten yaml -Definition in eine Datei mit dem Namen cleanup.yaml. Lösen Sie einen Pod aus, um die alten Protokolle zu bereinigen:
    kubectl apply -f cleanup.yamlkubectl apply -f cleanup.yaml
  4. Details zum Fortschritt abrufen:

    kubectl -n uipath-infra logs cleanup-old-logs -fkubectl -n uipath-infra logs cleanup-old-logs -f
  5. Löschen Sie den Auftrag:

    kubectl delete -f cleanup.yamlkubectl delete -f cleanup.yaml
