Configure Ingress for Pulse on Kubernetes in GKE

Use this procedure to configure NGINX Ingress for Pulse services deployed on a Kubernetes cluster in Google Kubernetes Engine (GKE).

Prerequisites

Before you begin, ensure that:

• Pulse is deployed on the Kubernetes cluster.

• You have kubectl access to the target cluster.

• Helm is installed and configured.

• The Pulse services are available in the target namespace.

Add the NGINX Ingress Helm Repository

Run the following commands:

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx 
helm repo update

Install NGINX Ingress Controller

Install the NGINX Ingress Controller in the ingress-nginx namespace:

helm install ingress-nginx ingress-nginx/ingress-nginx \
 --namespace ingress-nginx \
 --create-namespace

Verify the External IP Address

Run the following command to verify that the Ingress Controller service has an external IP address:

kubectl get svc -n ingress-nginx

Expected output:

NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
ingress-nginx-controller LoadBalancer <IP Address 1> <IP Address 3>8 80:30946/TCP,443:31828/TCP 27h
ingress-nginx-controller-admission ClusterIP <IP Address 2> <none> 443/TCP 27h

Create the Ingress for Pulse Backend Services

Create a file named ingress.yaml with the following content:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
 name: pulse-ingress
 namespace: pulse
 annotations:
 nginx.ingress.kubernetes.io/use-regex: "true"
 nginx.ingress.kubernetes.io/rewrite-target: /$2
spec:
 ingressClassName: nginx
 rules:
 - http:
 paths:

 - path: /manager(/|$)(.*)
 pathType: ImplementationSpecific
 backend:
 service:
 name: accelo-manager
 port:
 number: 20001
 - path: /streaming(/|$)(.*)
 pathType: ImplementationSpecific
 backend:
 service:
 name: ad-streaming
 port:
 number: 19005
 - path: /hydra(/|$)(.*)
 pathType: ImplementationSpecific
 backend:
 service:
 name: ad-hydra
 port:
 number: 19072
 - path: /axnserver(/|$)(.*)
 pathType: ImplementationSpecific
 backend:
 service:
 name: ad-axnserver
 port:
 number: 19999
 
 - path: /profiler(/|$)(.*)
 pathType: ImplementationSpecific
 backend:
 service:
 name: ad-pulse-profiler
 port:
 number: 19029

Apply the file:

kubectl apply -f ingress.yaml

Verify the Ingress Configuration

Run the following command:

kubectl get ingress -n pulse

Confirm that both pulse-ingress and pulse-ui-ingress are created successfully.

Create the Ingress for the Pulse UI Service

Create a file named ui-ingress.yaml with the following content:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
 name: pulse-ui-ingress
 namespace: pulse

spec:
 ingressClassName: nginx

 rules:
 - http:
 paths:
 - path: /
 pathType: Prefix
 backend:
 service:
 name: ad-pulse-ui
 port:
 number: 4100

Apply the file:

kubectl apply -f ui-ingress.yaml

Access the Pulse UI

Use the external IP address of the ingress-nginx-controller service to access Pulse.

Example:

http://<EXTERNAL-IP>

Replace <EXTERNAL-IP> with the external IP address displayed in the kubectl get svc -n ingress-nginx output.
