Ingress for any Kubernetes environment

While developing, testing and running workloads it’s always important to have an easy way to access those applications. Every cloud load balancer slightly differs in configuration, pricing and ease of use.

With Web Relay ingress controller it doesn’t matter if your application runs on Minikube, GKE, AWS or Azure; all applications get same endpoints with exactly the same ingress configuration.

Relay Ingress with Kuard

Here, we add ingress controller from a hosted manifest and provide credentials via relay ingress init command. Webhook Relay ingress controller can be found in webrelay-ingress namespace.

To do it on your own, you will need:

• Kubernetes environment (in the example above we use Minikube)

• Configured kubectl

• Webhook Relay account

Add ingress controller to your environment. Learn more here.

Run:

relay ingress init

This command:

• Creates webrelay-ingress namespace

• Creates webrelay service account

• Creates deployment with the controller

• Creates cluster role and binding

• Generates access key and secret for the Web Relay server and supplies them as a Kubernetes secret

Get your tunnel domain name

$ relay tunnel create --group webrelay-ingress hello-ingress
2p4ptkh9vutgm8tqavigja.webrelay.io<---->http://127.0.0.1

Here, 2p4ptkh9vutgm8tqavigja.webrelay.io is your tunnel endpoint, set it in ingress.yaml file.Add Kuard to your cluster

In this example we are using Kuard workload. Deployment file and ingress configuration is available in https://github.com/webrelay/ingress repository under examples directory. Clone it:

git clone https://github.com/webrelay/ingress
cd ingress/examples

Now, edit ingress.yaml with your Host.

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: webrelay    
  name: relay-ingress
  namespace: default
spec:
  rules:
    - host: 2p4ptkh9vutgm8tqavigmp.webrelay.io # <- set your tunnel host here
      http:
        paths:
        - path: /
          backend:
            serviceName: kuard
            servicePort: 8080

Then create Kuard and ingress resource:

kubectl create -f kuard.yaml -f ingress.yaml
