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.

What now

We explored how we can add Jenkins to the mix and make it scale any service. We used relative scaling and made sure that there are some limits so that the service will always be within some boundaries.

Jenkins, by itself, proved to be very flexible and allowed us to set up a reasonably bullet-proof scaling mechanism with only a few lines of Declarative Pipeline code. Unfortunately, we hit some limits when integrating Alertmanager with Jenkins. As a result, Alertmanager config is not as generic as we'd like it to be. We might revisit that subject later and apply some alternative strategy. We might want to extend it. The solution might be called Docker Flow Alertmanager. Or, we might choose to replace Jenkins with our own solution. Since I'm fond of names that start with Docker Flow, we might add Scaler to the mix. We might opt for something completely unexpected...
