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.

Preface

Splunk App and Saved Searches

Splunk apps are a way for you to separate your data, searches, reports, and dashboards into separate areas where you can then configure who can access what. Splunk provides a large ecosystem to help third-party developers and companies provide these apps to the general public.

We mentioned earlier in this chapter that Splunk also provides "SplunkBase" for approved apps that have been certified for users by Splunk, such as apps for Cisco Network Devices. It doesn't need to be an approved app for it to be available for use on your system. Splunk allows you to create apps of your own, and if you need to, you can distribute them in a packaged file across to users who wish to use them. The whole point of Splunk apps, dashboards, and saved searches is to reduce the amount of work that is duplicated, as well as providing information to non-technical users when needed.

The following exercise will provide you with some hands-on experience...
