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.

Summary

This chapter taught you how applications such as Splunk can help you monitor and troubleshoot your applications by aggregating your container logs into one central area. We started this chapter with a discussion on the importance of a log management strategy when working with Docker, and then introduced Splunk by discussing its architecture, as well as some of the finer points on how to run the application.

We worked directly with Splunk, running the Docker container image, and started to forward logs from our running system. We then used the Splunk log driver to send our container logs directly to our Splunk container, mounting important directories to make sure our data was saved and available even after we stopped our container from running. Finally, we took a closer look at the Splunk query language, with which we created dashboards and saved searches and considered the advantages of the Splunk app ecosystem.

The next chapter will introduce Docker plugins and teach...
