Use IBM ingress domain

In the previous step, the application was accessed with a not standard port. The service was exposed by way of Kubernetes NodePort feature.

Paid clusters come with an IBM-provided domain. This gives you a better option to expose applications with a proper URL and on standard HTTP/S ports.

Using the Kubernetes Ingress, you can set up the cluster inbound connection to the service:

1. Identify your IBM-provided Ingress domain. Replace <CLUSTER_NAME> with the cluster assigned to you:
   Windows

   Bash

   ibmcloud ks cluster-get <CLUSTER_NAME>

   ibmcloud ks cluster-get <CLUSTER_NAME>

   to find

   Ingress subdomain: mycluster.us-south.containers.appdomain.cloud
   Ingress secret:    mycluster
   

2. Create an Ingress file ingress-ibmdomain.yml pointing to your domain with support for HTTP and HTTPS. Use the following file as a template, replacing all the values wrapped in <> with the appropriate values from the above output. service-name is the name under ==> v1/Service in the above step or run kubectl get svc to find the service name of type NodePort.

   apiVersion: extensions/v1beta1
   kind: Ingress
   metadata:
     name: ingress-for-ibmdomain-http-and-https
   spec:
     tls:
     - hosts:
       -  <nameofproject>.<ingress-sub-domain>
       secretName: <ingress-secret>
     rules:
     - host: <nameofproject>.<ingress-sub-domain>
       http:
         paths:
         - path: /
           backend:
             serviceName: <service-name>
             servicePort: 9080
   

3. Deploy the Ingress

   kubectl apply -f ingress-ibmdomain.yml
   

4. Access your application at https://<nameofproject>.<ingress-sub-domain>
