I have two apps (workloads): app1 and app2. My goal is to redirect trafic from app1 to app2 if there is the diona prefix. For example:
app1/diona > app2/<api>
Now I have such rules:
rules:
- host: host
http:
paths:
- backend:
serviceName: ingress-37ce1ad1e8214375784d1e50805c056c
servicePort: 80
path: /diona
When I check app1/diona endpoint in logs of app2 there is an error:
Not Found: /diona
How can I redirect trafic correctly without realizing diona prefix in app2?
You can achieve it using nginx ingress controller. You code will look like this
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
name: rewrite
spec:
rules:
- host: host
http:
paths:
- backend:
serviceName: ingress-37ce1ad1e8214375784d1e50805c056c
servicePort: 80
path: /diona
If you want to redirect app1/diona/* to app2/*, change annotations to
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$1
name: rewrite
spec:
rules:
- host: host
http:
paths:
- backend:
serviceName: ingress-37ce1ad1e8214375784d1e50805c056c
servicePort: 80
path: /diona/(.*)

I have a kubeadm cluster and i am trying to deploy to static websites using ingress (after installing the metalLB and nginx-ingress controller )
After deploying the ingress, i find that the ingress don't load the website assets (the html file only)
Please any help !
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /

rules:
- host: k8s.example.k8s
http:
paths:
- path: /app1

number: 80
- path: /app2

Make sure your routing working properly with ingress
Example and it's not 404 for css:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: ingress-service
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
rules:
- http:
paths:
- path: /?(.*)
backend:
serviceName: service
servicePort: 3000
- path: /api/?(.*)
backend:
serviceName: service
servicePort: 5000

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:

annotations:
kubernetes.io/ingress.class: nginx
# nginx.ingress.kubernetes.io/use-regex: "true"
# nginx.ingress.kubernetes.io/rewrite-target: /
spec:
rules:

# pathType: Exact

I must say I have challenges hitting the admin backend. It just doesn't load i.
I have a service running on Kubernetes available on a domain like example.com. I'm trying to add a path which should redirect to a wordpress blog. So I need to add a rule: everithing that goes in /blog/ should redirect to wordpress, otherwise use the main app.
I tried to include a regexp for the main application path to include all except /blog/
- host: example.com
http:
paths:
- path: /^(?!blog).*$
but I keep getting must be a valid regex or if I remove the slash, it says must be an absolute path. I can't seem to find a way how to do that, it just keeps redirecting to my root app
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
name: app
annotations:
kubernetes.io/ingress.class: nginx
spec:
rules:
- host: example.com
http:
paths:
- path: /
backend:
serviceName: MainAppService
servicePort: 3010
- path: /blog/*
backend:
serviceName: BlogService
servicePort: 3020
Try this -
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$1
kubernetes.io/ingress.class: nginx
name: app
spec:
rules:
- host: example.com
http:
paths:
- path: /(.*)
backend:
serviceName: MainAppService
servicePort: 3010
- path: /blog/(.*)
backend:
serviceName: BlogService
servicePort: 3020
I guess, this should work
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
I have 2 questions:
1) I have a kubernetes cluster with multiple services and I want to use ingress to dynamically redirect the traffic to the cluster.
I expect the configuration to look something like this:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: test
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
rules:
- host: foo.bar.com
http:
paths:
- path: /service1/*
backend:
serviceName: service1
servicePort: 80
path: /*
- path: /service2/*
backend:
serviceName: service2
servicePort: 80
path:/*
So basically I want all the traffic to /service1/endpoint to be redirected to s1:80/endpoint dynamically.
2) Let's say I have 2 web services - service1 & service2.
I want the users to work with the following URL in their browser:
kube/serviceN/endpoint
Is there a way to do that without having my users redirected to service1/endpoint?
Thanks!
I believe your ingress definition to be almost correct:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: test
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
rules:
- host: foo.bar.com
http:
paths:
- path: /service1
backend:
serviceName: service1
servicePort: 80
- path: /service2
backend:
serviceName: service2
servicePort: 80
This should work if you have an ingress correctly deployed!
I hope I have understood your question properly but if so, what you have provided as an example is pretty close to the mark. The below config should work as described.
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: test
spec:
rules:
- host: foo.bar.com
http:
paths:
- path: /service1/
backend:
serviceName: service1
servicePort: 80
- path: /service2/
backend:
serviceName: service2
servicePort: 80
Good luck :)
