Lab description

If you're building and deploying cloud-native applications and microservices, then Kubernetes is the must-have platform. Kubernetes provides superior container-orchestration, deployment, scaling, and management. When it comes to securing application traffic within Kubernetes, consider using Network Policies.

Being able to consume Kubernetes hosted services externally is a common requirement. Kubernetes provides the Ingress resource type to implement this requirement. In this lab, you learn how to deploy an Nginx Ingress Controller and install and expose a sample API service using an Ingress resource.

Lab Objectives

Upon completion of this lab, you will be able to:

You should:

  • Be comfortable with basic Linux command line administration
  • Be comfortable with basic Kubernetes cluster administration

Lab Environment

This lab will start with the following AWS resources provisioned automatically for you:

  • A single EC2 instance, named k8s.cluster.cloudacademy.platform.instance, which will have a public IP address attached. This will be the instance that you will connect to using your local workstation browser.

To achieve the lab end state, you will be walked through the process of:

  • Using your local workstation browser to remotely connect to k8s.cluster.cloudacademy.platform.instance
  • Install and setup the Nginx Ingress Controller
  • Deploy a ready made Programming Languages themed API into a Kubernetes cluster
  • Create and deploy an Ingress resource to expose the API externally
  • Test and validate the API externally
