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.

Creating the cluster and deploying services

We'll start by recreating the cluster and deploying the stacks that we used in the previous chapter.

All the commands from this chapter are available in the 06-alert-humans.sh Gist at https://gist.github.com/vfarcic/2cdd86977b22288313345a2ca0416fe9.
chmod +x scripts/dm-swarm-06.sh
  
./scripts/dm-swarm-06.sh
    
eval $(docker-machine env swarm-1)

We executed the dm-swarm-06.sh script which, in turn, created a Swarm cluster composed of Docker machines, created the networks and deployed the stacks. Now we should wait a few moments until all the services in the monitor stack are up and running. Please use docker stack ps monitor command to confirm that the status of all the services in the stack is Running.

Finally, we'll confirm that everything is deployed correctly by opening Prometheus in a browser.
