Docker High Performance. - Second Edition

Overview of this book

Docker is an enterprise-grade container platform that allows you to build and deploy your apps. Its portable format lets you run your code right from your desktop workstations to popular cloud computing providers. This comprehensive guide will improve your Docker work?ows and ensure your application's production environment runs smoothly. This book starts with a refresher on setting up and running Docker and details the basic setup for creating a Docker Swarm cluster. You will then learn how to automate this cluster by using the Chef server and cookbooks. After that, you will run the Docker monitoring system with Prometheus and Grafana, and deploy the ELK stack. You will also learn best practices for optimizing Docker images. After deploying containers with the help of Jenkins, you will then move on to a tutorial on using Apache JMeter to analyze your application's performance. You will learn how to use Docker Swarm and NGINX to load-balance your application, and how common debugging tools in Linux can be used to troubleshoot Docker containers. By the end of this book, you will be able to integrate all the optimizations that you have learned and put everything into practice in your applications.

Alternative methods


There are other general-purpose configuration management tools that allow us to configure our Docker host. The following is a short list of the other tools that we can use:

  • Puppet: Refer to http://puppetlabs.com.
  • Ansible: This can be found at http://ansible.com.
  • CFEngine: This is available at http://cfengine.com.
  • SaltStack: You can find more on this at http://saltstack.com.
  • Docker Machine: This is a very specific configuration management tool that allows us to provision and configure Docker hosts in our infrastructure. More information about Docker Machine can be found on the Docker documentation page at https://docs.docker.com/machine.

If we do not want to manage our Docker host infrastructure at all, we can use Docker hosting services. Popular cloud providers started offering Docker hosts as a preprovisioned cloud image that we can use. Others offer a more comprehensive solution that allows us to interact with all the Docker hosts in the cloud as a single virtual Docker host...
