What am I going wrong in the below query?
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: nginx-ingress
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
rules:
- http:
paths:
- path: /nginx
backend:
serviceName: nginx
servicePort: 80
The error I am getting:
error validating "ingress.yaml": error validating data: [ValidationError(Ingress.spec.rules[0].http.paths[0].backend): unknown field "serviceName" in io.k8s.api.networking.v1.IngressBackend, ValidationError(Ingress.spec.rules[0].http.paths[0].backend): unknown field "servicePort" in io.k8s.api.networking.v1.IngressBackend]; if you choose to ignore these errors, turn validation off with
--validate=false
Ingress spec has changed since updated to v1. Try:
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: nginx-ingress
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
rules:
- http:
paths:
- path: /nginx
pathType: ImplementationSpecific
backend:
service:
name: nginx
port:
number: 80
According to this documentation you need to change ServiceName and ServicePort.
Each HTTP rule contains (...) a list of paths (for example, /testpath), each of which has an associated backend defined with a service.name and a service.port.name or service.port.number. Both the host and path must match the content of an incoming request before the load balancer directs traffic to the referenced Service.
Here is your yaml file with corrections:
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: nginx-ingress
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
rules:
- http:
paths:
- path: /nginx
backend:
service:
name: nginx
port:
number: 8080
ServiceName and ServicePort no keywords are available like that in v1 .
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: nginx-ingress
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
rules:
- http:
paths:
- path: /nginx
backend:
service:
name: nginx
port:
number: 8080
service name and service port syntax is incorrect. Follow the below sample
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: minimal-ingress
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
ingressClassName: nginx-example
rules:

pathType: Prefix
backend:
service:
name: test

currently I'm trying the following setup:
I have:
one cluster
one Ingress Controller
one url (myapp.onazure.com)
two namespaces for two applications default and default-test
two deployments, ingress objects, services for the namespaces
I can easily reach my app from the default namespace with path based routing '/' as a prefix rule
Now i have tried to configure the second namespace and following rule: /testing to hit another service
Unfortunately i get an HTTP404 when i try to hit the following URL myapp.onazure.com/testing/openapi.json
What did I miss?

Not working Ingress 2

apiVersion: networking.k8s.io/v1
metadata:

annotations:
kubernetes.io/ingress.class: public-nginx

http:
paths:

#pathType: Prefix
backend:
service:
name: liveapi-svc-testing
port:

Maybe I am missing a rewrite target to simply '/' in the testing namespace ingress?
Finally I figured out the missing part. I had to add the following statement to the not working ingress object:
annotations:
kubernetes.io/ingress.class: public-nginx
nginx.ingress.kubernetes.io/use-regex: "true"
nginx.ingress.kubernetes.io/rewrite-target: /$1
Please see the complete ingress object:
kind: Ingress
apiVersion: networking.k8s.io/v1
metadata:
name: liveapi-ingress-object
namespace: default-testing
annotations:
kubernetes.io/ingress.class: public-nginx
nginx.ingress.kubernetes.io/use-regex: "true"
nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
tls:
- hosts:

secretName: ingress-tls-csi-testing
rules:

http:
paths:

pathType: Prefix
backend:
service:

port:

Use full DNS name of a service,
$SERVICE.$NAMESPACE.svc.cluster.local
But you need to make sure your ignress controller has acccess to the desired namespace.
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

and this is yaml for rewrite /blob/

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

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 am trying to write an ingress for a rest api service but I am seeing "default backend 404"

I would to build following an service deployed to kubernetes to be accessed using an ingress object.
I would like to use https://mylocation.com/myprogram/doc to access the app but only https://mylocation.com/myprogram/doc/ works.
I have created the following entry in my yaml
# -----------------
# Ingress object
# -----------------
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: myapp-ingress
namespace: documentation
annotations:
kubernetes.io/ingress.class: nginx
#Default is 'true'
spec:
tls:
- hosts:
- mylocation.com
rules:
- host: mylocation.com
http:
paths:
- backend:
serviceName: myapp-service
servicePort: 80
path: /myapp/doc
- backend:
serviceName: myapp-service
servicePort: 80
path: /myapp/doc/(.*)
I have created the ingress object kubectl apply -f filename
When I browse http://mylocation.com//myapp/doc, I get HTTP ERROR 404
When I browse http://mylocation.com//myapp/doc/, It works
Can someone help me to get http://mylocation.com//myapp/doc working?
Thanks for your help.
Make sure to place appropriate regex

I am using abc.com/foo and it is working fine, but whatever url like abc.com/foo/account-login I need to redirect to abc.com/account-login and it is not working. Please let me know how can I set rewrite or any other annotatios in traefik.
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
traefik.frontend.rule.type: PathPrefixStrip

- host: abc.com

paths:
- backend:
serviceName: dev-service
servicePort: http
path: /foo

- host: abc.com
http:
paths:

servicePort: http

It depends on your back-and configuration but probably you can try:
remove traefik.frontend.rule.type: PathPrefixStrip" and set path: /
Please let me know if its helps
