Overview of this book

No doubt Docker Containers are the future of highly-scalable software systems and have cost and runtime efficient supporting infrastructure. But learning it might look complex as it comes with many technicalities. This is where The Docker Workshop will help you. Through this workshop, you’ll quickly learn how to work with containers and Docker with the help of practical activities.? The workshop starts with Docker containers, enabling you to understand how it works. You’ll run third party Docker images and also create your own images using Dockerfiles and multi-stage Dockerfiles. Next, you’ll create environments for Docker images, and expedite your deployment and testing process with Continuous Integration. Moving ahead, you’ll tap into interesting topics and learn how to implement production-ready environments using Docker Swarm. You’ll also apply best practices to secure Docker images and to ensure that production environments are running at maximum capacity. Towards the end, you’ll gather skills to successfully move Docker from development to testing, and then into production. While doing so, you’ll learn how to troubleshoot issues, clear up resource bottlenecks and optimize the performance of services. By the end of this workshop, you’ll be able to utilize Docker containers in real-world use cases.

13. Monitoring Docker Metrics

Overview

This chapter will provide you with the skills needed to set up a monitoring environment for your system to start collecting container and resource metrics. By the end of this chapter, you will be able to devise a monitoring strategy for your metrics and determine what you need to think about before you start development on your project. You will also implement a basic Prometheus configuration on your system. The chapter will extend your knowledge of Prometheus by exploring the user interface, the PromQL query language, configuration options, and the collection of your Docker and application metrics. It will also enhance your visualizations and dashboarding with the inclusion of Grafana as part of your Prometheus installation.
