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.

Deploying services

We'll start by deploying the stacks we used so far. We will not modify them in any form or way but deploy them as they are. Further on, we'll explore what modifications we should add to those stacks to make them more production-ready.

We'll execute scripts/aws-services.sh (https://github.com/vfarcic/docker-flow-monitor/blob/master/scripts/aws-services.sh) script that contains all the commands we used thus far.

Please replace [...] with the DNS of your cluster.

export CLUSTER_DNS=[...] 
 
curl -o aws-services.sh \ 
    https://raw.githubusercontent.com/vfarcic/docker-\
flow-monitor/master/scripts/aws-services.sh chmod +x aws-services.sh

The commands we executed created the environment variable CLUSTER_DNS, downloaded the script, and assigned it execute permissions.

We won't go into details of the script since it deploys the same stacks...
