I'm running into issues with my ingress.yml. Getting this error:

error: error validating "ingress.yml": error validating data: [ValidationError(Ingress.spec.rules[0].http.paths[0].backend): unknown field "service.name" in io.k8s.api.networking.v1.IngressBackend, ValidationError(Ingress.spec.rules[0].http.paths[0].backend): unknown field "service.port.number" in io.k8s.api.networking.v1.IngressBackend, ValidationError(Ingress.spec.rules[0].http.paths[1].backend): unknown field "service.name" in io.k8s.api.networking.v1.IngressBackend, ValidationError(Ingress.spec.rules[0].http.paths[1].backend): unknown field "service.port.number" in io.k8s.api.networking.v1.IngressBackend];

Based on this documentation serviceName changed to service.name and servicePort changed to service.port and so on. Here is the ingress file:

CodePudding user response：

Kubernetes has a special treatment for YAML format, so basically, you just need to extend the properties individually the service.name and service.port.number:

...
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: bitwarden
                port:
                  number: 80
          - path: /notifications/hub
            pathType: Exact
            backend:
              service:
                name: bitwarden
                port:
                  number: 3012
