This topic describes how to perform URL rewrite for Kubernetes ingress resources for VMware Tanzu Kubernetes Grid Integrated Edition (TKGI).

About Support for URL Rewrite for Ingress Resources

Tanzu Kubernetes Grid Integrated Edition supports ingress URL path rewrite using NSX-T or NSX v2.5.1+ and NCP v2.5.1+.

All the ingress paths will be rewritten to the provided value. If an ingress has annotation ingress.kubernetes.io/rewrite-target: / and has path /tea, for example, the URI /tea will be rewritten to / before the request is sent to the backend service. Numbered capture groups are supported.

URL Rewrite Example

The following example shows how to implement URL rewrite.

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: cafe-ingress
  annotations:
    kubernetes.io/ingress.class: "nsx"
    ncp/use-regex: "True"
    #/tea/cup will be rewritten to /cup before sending request to endpoint
    ingress.kubernetes.io/rewrite-target: /$1
spec:
  rules:
  - host: cafe.example.com
    http:
      paths:
      - path: /tea/(.*)
        pathType: Prefix
        backend:
          service:
            name: tea-svc
            port:
              number: 80
      - path: /coffee/(.*)
        pathType: Prefix
        backend:
          service:
            name: coffee-svc
            port:
              number: 80
