Many applications are built to serve the outside world. As such, managing external access to an application is a crucial part of Kubernetes application design. In this lab, you will have the opportunity to use Services and Ingress to expose an application to the outside world.
Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- Create a Service to Expose the Application
The application’s Deployment is called
hive-io-frontendand exists in thehiveNamespace.The application’s web server listens on port
80. Create a Service calledhive-io-frontend-svcto expose this application on port8080. The Service only needs to expose the application within the cluster network.- Expose the Application Externally Using an Ingress
Create an Ingress to expose the application.
An Ingress controller is already installed. You can use
nginxfor theingressClassName.Configure the application use
hive.iofor the domain. The lab server already has an entry in/etc/hostsset 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.
