Helm安装报错：Ingress缺少paths字段，求排查values.yaml问题

报错信息 #

Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: 
error validating "": 
error validating data: ValidationError(Ingress.spec.rules[0].http): 
missing required field "paths" in io.k8s.api.networking.v1.HTTPIngressRuleValue

问题根源 #

你的values.yaml里Ingress的paths配置存在缩进错误，pathType字段的缩进层级不对，导致Kubernetes无法正确识别合法的paths结构，从而抛出"缺少paths字段"的验证错误。原配置中pathType缩进在backend内部，它应该和path、backend处于同一层级。

修正后的配置 #

ingress:
  enabled: true
  className: ""
  annotations:
    #  kubernetes.io/ingress.class: nginx
    # kubernetes.io/tls-acme: "true"
    alb.ingress.kubernetes.io/target-type: ip
    kubernetes.io/ingress.class: alb
    alb.ingress.kubernetes.io/scheme: internet-facing
  hosts:
    - host: metabasea0000125955
      paths:
      - path: /
        backend:
          service:
            name: test
            port:
              number: 3000
        pathType: Prefix  # 调整缩进，与path、backend同级

说明 #

修正后pathType与path、backend对齐，符合Kubernetes Ingress v1版本的结构要求，Helm就能正确生成合法的Ingress资源清单，通过K8s的验证。
