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.

Infrastructure tasks

Infrastructure tasks are related to flows that are in charge of making sure that hardware is operational and that nodes are forming the cluster. Just as service replicas, those nodes are dynamic. Their numbers are fluctuating as a result of ever-changing needs behind our services. Everything related to hardware or, more often, VMs and their ability to be members of a cluster is under this umbrella.

We'll group infrastructure related tasks into self-healing, request, and self-adaptation flows.

Self-healing flow

A system that automatically manages infrastructure is not much different from the system we built around services. Just as Docker Swarm (or any other scheduler) is in charge of making sure that...
