Puedo acceder al tablero de kubernetes obteniendo su URL usando minikube dashboard --url. Sin embargo, al utilizar este enfoque, se utiliza un nombre de puerto diferente cada vez que reinicio el clúster Minikube. Por lo tanto, intento agregar ingress-nginxy exponer el servicio kubernetes-dashoard:
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: k8s-dashboard-ingress
namespace: kubernetes-dashboard
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
rules:
- host: kube-dashboard.local
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: kubernetes-dashboard
port:
number: 80
kube-dashboard.localse asigna a la dirección IP de la dirección IP del clúster mediante /etc/hosts. Esto parece funcionar y el navegador obtiene contenido inicial, pero la ventana del navegador permanece vacía. Parece que solo la solicitud inicial se enruta al panel, pero las otras solicitudes de los recursos JS fallan de alguna manera. ¿Qué hay de malo con la regla de ingreso?
