k8s ingress setup - invalid type for io.k8s.api.networking.v1.ServiceBackendPort.number: got "string", expected - kubernetes

Question

I'm trying to setup an ingress in kubernetes for my frontend, the code is as below.
datahub-frontend:
enabled: true
image:
repository: linkedin/datahub-frontend-react
tag: "v0.8.31"
ingress:
enabled: true
annotations:
kubernetes.io/ingress.class: alb
alb.ingress.kubernetes.io/scheme: internet-facing
alb.ingress.kubernetes.io/target-type: instance
alb.ingress.kubernetes.io/certificate-arn: arn:aws:acm:ap-southeast-2:601628467906:certificate/xxxxxxxxxxxxx
alb.ingress.kubernetes.io/inbound-cidrs: 0.0.0.0/0
alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}, {"HTTPS":443}]'
alb.ingress.kubernetes.io/actions.ssl-redirect: '{"Type": "redirect", "RedirectConfig": { "Protocol": "HTTPS", "Port": "443", "StatusCode": "HTTP_301"}}'
hosts:
- host: xxxxx.com
redirectPaths:
- path: /*
name: ssl-redirect
port: use-annotation
paths:
- /*
This is giving me the following error.
Error: UPGRADE FAILED: error validating "": error validating data: ValidationError(Ingress.spec.rules[0].http.paths[0].backend.service.port.number): invalid type for io.k8s.api.networking.v1.ServiceBackendPort.number: got "string", expected "integer"

Answer 1

seems like the ingress definition you posted is incorrect. It is missing the required spec and rules according to kubernetes doc.
This contains an example ingress for ssl-redirect
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
namespace: default
name: ingress
annotations:
alb.ingress.kubernetes.io/certificate-arn: arn:aws:acm:us-west-2:xxxx:certificate/xxxxxx
alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}, {"HTTPS":443}]'
alb.ingress.kubernetes.io/ssl-redirect: '443'
spec:
ingressClassName: alb
rules:
- http:
paths:
- path: /users/*
pathType: ImplementationSpecific
backend:
service:
name: user-service
port:
number: 80
- path: /*
pathType: ImplementationSpecific
backend:
service:
name: default-service
port:
number: 80
I see that you are using actions annotation, you need to specify Ingress.spec.rules[0].http.paths[0].backend.service.port.name with use-annotation. Make sure Ingress.spec.rules[0].http.paths[0].backend.service.port.number is not used.
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: my-ingress
annotations:
...
...
alb.ingress.kubernetes.io/actions.my-rule: '{"type":"fixed-response","fixedResponseConfig":{"contentType":"text/plain","statusCode":"200","messageBody":"hello world"}}'
spec:
rules:
- http:
paths:
- path: /*
pathType: ImplementationSpecific
backend:
service:
name: my-rule
port:
name: use-annotation
