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.

Developer's role in the system

The human domain consists of processes and tools that are operated manually. We are trying to move away from that domain all the actions that are repeatable. That does not mean that the goal is for that domain to disappear. Quite the contrary. By pushing repetitive tasks away from it, we are freeing ourselves from mundane tasks and increasing the time we spend with those that bring real value. The less we do the tasks that can be delegated to machines, the more time we can spend with those that require creativity. This philosophy is in line with strengths and weaknesses of each actor in this drama. Machines are good at crunching numbers. They know how to execute predefined operations very fast. They are much better and more reliable at that than us. Unlike machines, we are capable of critical thinking. We can be creative. We can program those...
