Привет, я новичок в Kubernetes и helm и недавно попробовал один учебник от Pluralsight.

Согласно учебнику, мой входной файл выглядит следующим образом —

 apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: {{ .Release.Name }}-{{ .Chart.Name }}-ingress
spec:
  rules:
{{- range .Values.ingress.hosts }}
  - host: {{ $.Release.Name }}.{{ .host.domain }}
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: {{ $.Release.Name}}-{{ .host.chart }}
            port:
              number: 80
{{- end }}
 

Когда я пытаюсь подключиться к ip-адресу minikube, он выдает мне эту ошибку —

 404 Not Found
----
nginx
 

Я установил диаграмму управления с помощью гостевой книги helm install dev
Это мой журнал стручков и входа —
Команда — kubectl get ingress —

и моя версия миникуба такова —

 minikube version: v1.23.0
commit: 5931455374810b1bbeb222a9713ae2c756daee10
 

Я добавил ip-адрес мини-куба с хостом в etc/hosts, так что этой проблемы нет

Попробуйте добавить ниже, чтобы исправить эту внутреннюю ошибку по умолчанию, и посмотрите, решит ли это проблему. Кроме того, было бы полезно проверить, совпадают ли ваш IP-адрес входа и IP-адрес мини-куба.

 spec:
  defaultBackend:
    service:
      name: {{ $.Release.Name}}-{{ .host.chart }}
      port:
        number: 80
