@mohamma-faud, I tried to install 2 nginx controllers with the above steps and they do not work. First ingress is fine and shows the load balance ip, but the second ingress never get the load balancer ip, it always shows pending

1st ingress:

helm install nginx-ingress ingress-nginx/ingress-nginx –namespace ingress-basic –set controller.replicaCount=1 –set controller.ingressClass=nginx1 –set controller.ingressClassResource.name=nginx1 –set controller.ingressClassResource.controllerValue=“k8s.io/nginx1” –set controller.ingressClassResource.enabled=true –set controller.ingressClassResource.default=true –set controller.IngressClassByName=true –set controller.nodeSelector.“beta.kubernetes.io/os”=linux –set defaultBackend.nodeSelector.“beta.kubernetes.io/os”=linux –set controller.admissionWebhooks.patch.nodeSelector.“beta.kubernetes.io/os”=linux –set controller.service.loadBalancerIP=“X.X.X.X” –set controller.service.annotations.“service.beta.kubernetes.io/azure-dns-label-name”=“test-services”

2ns ingress: helm install nginx-ingress2 ingress-nginx/ingress-nginx –namespace ingress-basic –set controller.replicaCount=1 –set controller.ingressClass=nginx2 –set controller.ingressClassResource.name=nginx2 –set controller.ingressClassResource.controllerValue=“k8s.io/nginx2” –set controller.ingressClassResource.enabled=true –set controller.IngressClassByName=true –set controller.nodeSelector.“beta.kubernetes.io/os”=linux –set defaultBackend.nodeSelector.“beta.kubernetes.io/os”=linux –set controller.admissionWebhooks.patch.nodeSelector.“beta.kubernetes.io/os”=linux –set controller.service.loadBalancerIP=“X.X.X.X” –set controller.service.annotations.“service.beta.kubernetes.io/azure-dns-label-name”=“test2-services”

Can you please help here ?

I was able to resolve it, actually i had to edit the tag in the public ip resources in the azure to fix it. Thanks

Thanks @mohammed-fuad and no need to explicitly define ingressClassName yaml?

No, that’s the responsibility of helm chart.

Hi @mohammed-fuad can you explain how it worked ? i mean we dont need to create the ingressClass manually right? just use it in helm install and refer it in your ingress file? helm --namespace staging install banking-api-stg ingress-nginx/ingress-nginx –set controller.ingressClass=staging \

Using –set controller.ingressClass=staging only not enough, ingressClassResource.name and ingressClassResource.controllerValue must be set

--set controller.ingressClass=staging \
--set controller.ingressClassResource.name=staging \
--set controller.ingressClassResource.controllerValue= "k8s.io/staging"

at your ingress definition you must define the ingressClassName as:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: test-api
  namespace: staging
spec:
    ingressClassName: staging

mybad … i edited it later so sorry about that

@longwuyuan It works finally without creating ingressClass manually, I deleted all the classes and re-installed helm as you recommended.

Thanks for your support.
