How can I configure service/path?

[subicura]

Is this a BUG REPORT or FEATURE REQUEST? (choose one):
Feature request

Kong Ingress controller version:
0.0.3

Kubernetes version (use kubectl version):
1.9.6

Environment:
Docker for mac

What happened:
I can't configure service/path.
I want to "http://localhost/sample" to "http://sample-http/external".

What you expected to happen:
Use Ingress or KongIngress .

Ingress (ingress.kubernetes.io/rewrite-target is not working)

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: sample-http
  annotations:
    ingress.kubernetes.io/rewrite-target: "/external"
spec:
  rules:
  - host: localhost
    http:
      paths:
      - path: /sample
        backend:
          serviceName: sample-http
          servicePort: 80

KongIngress (proxy/path is not working)

apiVersion: configuration.konghq.com/v1
kind: KongIngress
metadata:
  name: sample-http
proxy:
  path: /external
route:
  strip_path: true

It needs pull request?

You can try to add an annotation named "request-transformer.plugin.konghq.com" to the Ingress. see more info in https://github.com/Kong/kubernetes-ingress-controller/blob/master/deploy/minikube.md
I config the k8s Ingress like the guid and go right.

• ingress.yaml

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: proxy-from-k8s-to-mockbin
  namespace: kong
  annotations:
    request-transformer.plugin.konghq.com: |
      transform-request-to-mockbin
    jwt.plugin.konghq.com: |
      wechat-jwt
spec:
  rules:
  - host: foo.bar
    http:
      paths:
      - path: /request
        backend:
          serviceName: proxy-to-mockbin
          servicePort: 80

• svc.yaml

kind: Service
apiVersion: v1
metadata:
  name: proxy-to-mockbin
  namespace: kong
spec:
  ports:
  - protocol: TCP
    port: 80
  type: ExternalName
  externalName: mockbin.org

• request-transformer.yaml

apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
  name: transform-request-to-mockbin
  namespace: kong
config:
  remove:
    headers: host

@Daiyoung thanks for reply!

But, I want to tranform "path".

For example, I create 2 api(service/route).

• 'http://localhost/user-service/v1/users' => 'http://kube-user-service/external/v1/users'
• 'http://localhost/report-service/v1/reports' => 'http://kube-report-service/external/v1/reports'

Is it possible to use request-transformer?

@subicura kubernetes-ingress-controller for kong is released just a few days, the document is not very perfect. I also get some problems,like I can't create the jwt credential bound one consumer.
Yours issue is same to me, I will try again and then tell you.

Sorry to revive this post but I can't get this working 😕

I'm trying to configure a service using the /doc path.

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: html2doc-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
spec:
  rules:
  - http:
      paths:
      - path: /doc
        backend:
          serviceName: html2doc-svc
          servicePort: 80

My service receives calls at /{format} where format can be, among others, pdf.

apiVersion: configuration.konghq.com/v1
kind: KongIngress
metadata:
  name: html2doc-kongingress
proxy:
  path: /
route:
  strip_path: true

Even after adding the above KongIngress controller nothing seems to change. When I call /doc I can see in my pod logs that it's trying to access /doc:

Am I doing something wrong? BTW sorry to bother you, I'm kinda newbie in k8s....

[elboletaire]

Ok, I got it... the Ingress controller and the KongIngress controller need to have the same metadata.name. BTW if anyone can confirm me I'm not doing something evil, I'll thank them.

@elboletaire That's correct.

this seems to be a broken link now
