Challenge

Create a Service to Expose the Application

The application's Deployment is called hive-io-frontend and exists in the hive Namespace.

The application's web server listens on port 80. Create a Service called hive-io-frontend-svc to expose this application on port 8080. The Service only needs to expose the application within the cluster network.
Challenge

Expose the Application Externally Using an Ingress

Create an Ingress to expose the application.

An Ingress controller is already installed. You can use nginx for the ingressClassName.

Configure the application using hive.io for the domain. The lab server already has an entry in /etc/hosts set up for this domain, so you do not need to make any changes to /etc/hosts.

Remember that the application's Service listens on port 8080.
