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.

Kubernetes operations (kops) compared to Docker for AWS

Docker for AWS (D4AWS) quickly became the preferable way to create a Docker Swarm cluster in AWS (and Azure). Similarly, kops is the most commonly used tool to create Kubernetes clusters in AWS. At least, at the time of this writing.

The result, with both tools, is more or less the same. Both create Security Groups, VPCs, Auto-Scaling Groups, Elastic Load Balancers, and everything else a cluster needs. In both cases, Auto-Scaling Groups are in charge of creating EC2 instances. Both rely on external storage to keep the state of the cluster (kops in S3 and D4AWS in DynamoDB). In both cases, EC2 instances brought to life by Auto-Scaling Groups know how to run system-level services and join the cluster. If we exclude the fact that one solution runs Docker Swarm and that the other uses Kubernetes, there is no significant functional...
