Jump right into Kubernetes development with career-focused lessons and hands-on practice.

DevOps for Developers

Kubernetes is a powerful container management tool that's taking the world by storm. This detailed course will help you master it.

In this course, you'll start with the fundamentals of Kubernetes and what the main components of a cluster look like. You'll then learn how to use those components to build, test, deploy, and upgrade applications, as well as how to achieve state persistence once your application is deployed. You'll also learn how to secure your deployments and manage resources, which are crucial DevOps skills.

By the time you're done, you'll have a firm grasp on what Kubernetes is, as well as the skills to deploy your own clusters and applications with confidence.

A Practical Guide to Kubernetes

# Why usse Ingress objects?

Applications that are not accessible to users are useless. Kubernetes Services provide accessibility with a usability cost. Each application can be reached through a different port. We cannot expect users to know the port of each service in our cluster.

> **Note:** **Ingress** objects manage external access to the applications running inside a Kubernetes cluster.

 While it might seem that we have already accomplished that through Kubernetes Services, they do not make the applications truly accessible. We still need forwarding rules based on paths and domains, SSL termination, and a number of other features.

In a more traditional setup, we’d probably use an external proxy and a load balancer. Ingress provides an API that allows us to accomplish these things. It also has a few other features we expect from a dynamic cluster.
