I facing a problem in an ingress controller nginx kubernetes that is deployed in minikube :
when i included the route that nginx will use to redirect the request it didn't work , however when i remove the route it work :
So , as is explained in yaml file when i use /category it didn't work , however with with just / it is working

i found the solution
i removed nginx.ingress.kubernetes.io/rewrite-target: $1
and i added
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/use-regex: "true"
nginx.ingress.kubernetes.io/app-root: /
Can you try this -
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: spare-ingress-dev
namespace: default
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/rewrite-target: $1
spec:
rules:
- http:
paths:
- path: /(.*)
backend:
serviceName: cluster-test-ip
servicePort: 80
- path: /category/(.*)
backend:
serviceName: cluster-category-ip
servicePort: 5200

I am struggling with making a rewrite/redirect rule on nginx-ingress on Kubernetes.
According to the doc https://kubernetes.github.io/ingress-nginx/examples/rewrite/ it says it is possible with the annotation "nginx.ingress.kubernetes.io/rewrite-target", but unable to implement on my ingress. Maybe I am doing it wrong.
An example, portion of nginx-ingress yaml file.
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
kubernetes.io/ingress.class: nginx
example.com/deployment-name: frontend-page
example.com/ingress-hostnames: www.example.com
nginx.ingress.kubernetes.io/rewrite-target: /$2
spec:
rules:
- host: www.example.com
http:
paths:
- backend:
serviceName: frontend-page
servicePort: 8080
path: /front(/|$)(.*)
Tried another way around as well but no luck:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
kubernetes.io/ingress.class: nginx
example.com/deployment-name: frontend-page
example.com/ingress-hostnames: www.example.com
nginx.ingress.kubernetes.io/rewrite-target: /shop
spec:
rules:
- host: www.example.com
http:
paths:
- backend:
serviceName: frontend-page
servicePort: 8080
path: /
I want to redirect any traffic to the page www.example.com/front/checkdomain to www.example.com/checkdomain. I want to remove that "front" path comes in between.
try this with an updated API version, hope your ingress supports networking.k8s.io/v1beta1
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/rewrite-target: /$2
name: rewrite
namespace: default
spec:
rules:
- host: rewrite.bar.com
http:
paths:
- backend:
serviceName: http-svc
servicePort: 80
path: /something(/|$)(.*)
Example : https://kubernetes.github.io/ingress-nginx/examples/rewrite/#examples
The solution was
Changing from:
nginx.ingress.kubernetes.io/rewrite-target: /$2
To:
nginx.ingress.kubernetes.io/rewrite-target: /$2/
So the yaml looks like:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
kubernetes.io/ingress.class: nginx
example.com/deployment-name: frontend-page
example.com/ingress-hostnames: www.example.com
nginx.ingress.kubernetes.io/rewrite-target: /$2/
spec:
rules:
- host: www.example.com
http:
paths:
- backend:
serviceName: frontend-page
servicePort: 8080
path: /front(/|$)(.*)
i have tomcat backend service running on kubernetes cluster try to rewrite using ingress with path /blob/api/v1/test-backend > /api/v1/test-backend so
the configuration now is running so can hit to xx.somedomain.com/blob/api/v1/test-backend and i want change to xx.somedomain.com/api/v1/test-backend with rewrites
my basic ingress
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
name: ingress-blob
namespace: blob-test
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/ssl-redirect: "true"
nginx.ingress.kubernetes.io/proxy-body-size: 50m
spec:
tls:
- hosts:
- xx.somedomain.com
secretName: cert-key
rules:
- host: xx.somedomain.com
http:
paths:
- path: /blob/
backend:
serviceName: blob-service
servicePort: 8080
- path: /
backend:
serviceName: web-service
servicePort: 80
and this is yaml for rewrite /blob/
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
name: ingress-blob
namespace: blob-test
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/ssl-redirect: "true"
nginx.ingress.kubernetes.io/proxy-body-size: 50m
nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
tls:
- hosts:
- xx.somedomain.com
secretName: cert-key
rules:
- host: xx.somedomain.com
http:
paths:
- path: /blob/api/v1/some-backend
backend:
serviceName: blob-service
servicePort: 8080
when i test with api tester like talend is got 405 error
Try this
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$2
name: rewrite
namespace: default
spec:
rules:
- host: rewrite.bar.com
http:
paths:
- backend:
serviceName: http-svc
servicePort: 80
path: /something(/|$)(.*)
For example, the ingress definition above will result in the following rewrites:
rewrite.bar.com/something rewrites to rewrite.bar.com/
rewrite.bar.com/something/ rewrites to rewrite.bar.com/
rewrite.bar.com/something/new rewrites to rewrite.bar.com/new
Refer : https://kubernetes.github.io/ingress-nginx/examples/rewrite/
Try adding annotation like this
nginx.ingress.kubernetes.io/rewrite-target: "/$1"
I have a react app that works fine. However after putting it in k8s and installing ingress, whenever I refresh a page i get the following although it just refreshed the page. How do I correct this?
Here is a snippet of my yaml
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
name: my-ingress
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/use-regex: "true"
spec:
rules:
- http:
paths:
- path: /api/auth/*
backend:
serviceName: um-service
servicePort: 5001
- path: /api/profile/*
backend:
serviceName: um-service
servicePort: 5001
- path: /api/pass/*
backend:
serviceName: um-service
servicePort: 5001
---
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
name: admin-ingress
annotations:
kubernetes.io/ingress.class: nginx
# nginx.ingress.kubernetes.io/use-regex: "true"
# nginx.ingress.kubernetes.io/rewrite-target: /
spec:
rules:
- http:
paths:
- path: /admin
# pathType: Exact
backend:
serviceName: admin-service
servicePort: 4000
I must say I have challenges hitting the admin backend. It just doesn't load i.
I'm using ingress for kubernetes. My ingress is kubernetes nginx ingress. And routing configs don't work and redirect me root path in every request in https section All configs is given below
cat frontapi-ingress.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: swagger-ingress
annotations:
kubernetes.io/ingress.class: "nginx"
spec:
rules:
- host: preprod-ops.kblab.local
http:
paths:
- backend:
serviceName: kb-workplace
servicePort: 8080
path: /
- backend:
serviceName: gw-branch
servicePort: 8443
path: /api
$ cat swagger-portal.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: swagger-portal
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /

spec:
rules:
- host: preprod-ops.kblab.local
http:
paths:
- backend:
serviceName: swagger-portal
servicePort: 9001
path: /swagger-portal
Above config works properly with http config but, below config doesn't work with https config. It only works swagger-portal section
$cat frontapi-ingress-https.yaml

Thanks in advance.
You are setting the nginx.ingress.kubernetes.io/rewrite-target: / annotation on your swagger-portal-https.yaml Ingress, which explicitly implies the redirection to the root path.
If you want to preserve the request path, you need to remove this annotation.
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
namespace: default
name: my-ingress
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/rewrite-target: $2
spec:
rules:
- host: hostname.com
http:
paths:
- path: /
backend:
serviceName: frontend
servicePort: 80
- path: /api/v1(/|$)(.*)
backend:
serviceName: backend
servicePort: 80
What I am trying to accomplish here is:
hostname.com/api/v1/anyurl should become hostname.com/anyurl when it goes to the backend.
hostname.com/anyurl should remain hostname.com/anyurl and go to the frontend.
The /api/v1 rewrite seems to work, but any urls going to the frontend gets rewrited to /.
What I need is the rewrite rule to only apply to the /api/v1 path
I guess this should work for you -
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
namespace: default
name: my-ingress
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/rewrite-target: $1
spec:
rules:
- host: hostname.com
http:
paths:
- path: /(.*)
backend:
serviceName: frontend
servicePort: 80
- path: /api/(.*)
backend:
serviceName: backend
servicePort: 80
I have just edited this, it works for me, please check for this. I guess we can troubleshoot
