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.

Automating cluster setup

The first thing we should do is get the AWS credentials.

Please open the Amazon EC2 console (https://console.aws.amazon.com/ec2/v2/home), click on your name from the top-right menu, and select My Security Credentials. You will see the screen with different types of credentials. Expand the Access Keys (Access Key ID and Secret Access Key) section and click the Create New Access Key button. Expand the Show Access Key section to see the keys.

You will not be able to view the keys later on, so this is the only chance you'll have to Download Key File.

We'll put the keys as environment variables that will be used by the AWS Command Line Interface (AWS CLI) (https://aws.amazon.com/cli/).

Please replace [...] with your keys before executing the commands that follow.

All the commands from this chapter are available in the 14-self-healing-infra.sh Gist...
