Der Kubernetes Nginx-Container kann nicht auf den PHP-FPM-Container zugreifen
Ich habe 2 Kubernetes-Bereitstellungen für Nginx- und PHP-FPM-Laravel-Container erstellt. Aber aus irgendeinem Grund scheint der Datenverkehr von Nginx den PHP-FPM-Container nicht erfolgreich zu erreichen und erzeugt den folgenden Fehler
172.18.0.1 - - [18/Jul/2022:16:51:10 +0000] "GET / HTTP/1.1" 404 555 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.127 Safari/537.36"

Diese Docker-Datei läuft auch ohne Probleme einwandfrei. docker-composeDateien, die dieses Bild verwenden, funktionieren ebenfalls einwandfrei.
Irgendeine Idee, warum es vom nginx-deployment 容器的流量无法到达 api-web PHP-FPM-Container kommt und eine Fehlermeldung erhält
