The DevOps 2.2 Toolkit

By: Viktor Farcic

Overview of this book

Building on The DevOps 2.0 Toolkit and The DevOps 2.1 Toolkit: Docker Swarm, Viktor Farcic brings his latest exploration of the Docker technology as he records his journey to explore two new programs, self-adaptive and self-healing systems within Docker. The DevOps 2.2 Toolkit: Self-Sufficient Docker Clusters is the latest book in Viktor Farcic’s series that helps you build a full DevOps Toolkit. This book in the series looks at Docker, the tool designed to make it easier in the creation and running of applications using containers. In this latest entry, Viktor combines theory with a hands-on approach to guide you through the process of creating self-adaptive and self-healing systems. Within this book, Viktor will cover a wide-range of emerging topics, including what exactly self-adaptive and self-healing systems are, how to choose a solution for metrics storage and query, the creation of cluster-wide alerts and what a successful self-sufficient system blueprint looks like. Work with Viktor and dive into the creation of self-adaptive and self-healing systems within Docker.

Setting Up a Production Cluster

We explored quite a few techniques, processes, and tools that can help us build a self-sufficient system applied to services. Docker Swarm provides self-healing, and we created our own system for self-adaptation. By now, we should be fairly confident with our services and the time has come to explore how to accomplish similar goals applied to infrastructure.

The system should be capable of recreating failed nodes, of upgrading without downtime, and to scale servers depending on the fluctuating needs. We cannot explore those topics using clusters based on Docker machine nodes running locally. The capacity of our laptops is somewhat limited so we cannot scale nodes to a greater number. Even if we could, the infrastructure we'll use for production clusters is quite different. We'll need an API that will allow our system to communicate with...
