The DevOps 2.3 Toolkit

By: Viktor Farcic

Overview of this book

Building on The DevOps 2.0 Toolkit, The DevOps 2.1 Toolkit: Docker Swarm, and The DevOps 2.2 Toolkit: Self-Sufficient Docker Clusters, Viktor Farcic brings his latest exploration of the DevOps Toolkit as he takes you on a journey to explore the features of Kubernetes. The DevOps 2.3 Toolkit: Kubernetes is a book in the series that helps you build a full DevOps Toolkit. This book in the series looks at Kubernetes, the tool designed to, among other roles, make it easier in the creation and deployment of highly available and fault-tolerant applications at scale, with zero downtime. Within this book, Viktor will cover a wide range of emerging topics, including what exactly Kubernetes is, how to use both first and third-party add-ons for projects, and how to get the skills to be able to call yourself a “Kubernetes ninja.” Work with Viktor and dive into the creation and exploration of Kubernetes with a series of hands-on guides.

Using Ingress to Forward Traffic

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.

Ingress objects manage external access to the applications running inside a Kubernetes cluster. While, at first glance, it might seem that we 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, in addition to a few other features we expect from a dynamic cluster.

We'll explore...
