Redirect domain1 to domain2

1

I am using kong ingress controller and kong gateway in kubernetes. How do I redirect https://domain1.com to https://domain2.com?

Here’s my attempt:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: domain1-com
  annotations:
    konghq.com/protocols: https
    konghq.com/methods: "GET"
    konghq.com/plugins: "domain1-com-redirect"
    cert-manager.io/cluster-issuer: letsencrypt-prod
spec:
  ingressClassName: kong
  rules:
  - host: domain1.com
    http:
      paths:
      - path: /~/*
        pathType: ImplementationSpecific
        backend:
          service:
            name: lend-tech
            port:
              number: 443
  tls:
  - hosts:
    - domain1.com
    secretName: domain1-com-tls-certificate

kind: Service
apiVersion: v1
metadata:
  name: domain2-tech
  annotations:
    konghq.com/protocol: https
    konghq.com/host-header: domain2.tech
spec:
  ports:
    - name: https
      protocol: TCP
      port: 443
      targetPort: 443
  type: ExternalName
  externalName: domain2.tech

apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
  name: domain1-com-redirect
config: 
  header_filter:
    - kong.response.exit(301, 'Page moved - redirecting...', {['Location'] = 'https://domain2.tech'})
plugin: post-function
