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

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.
