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

Extending Prometheus with Grafana

The Prometheus web interface provides a functional expression browser that allows us to search and view the data in our time-series database with limited installation. It provides a graphical interface but doesn't allow us to save any of our searches or visualizations. The Prometheus web interface is also limited as it cannot group queries in dashboards. Also, there are not many visualizations that are provided by the interface. This is where we can expand our collected data further with the use of an application such as Grafana.

Grafana allows us to connect directly with the Prometheus time-series database and perform queries and create visually appealing dashboards. Grafana can run as a standalone application on a server. We can preconfigure the Grafana Docker image to deploy onto our system, configured with a connection to our Prometheus database, and with a basic dashboard already set up to monitor our running containers.

The following...
