When working with a distributed mission-critical application in production or in any production-like environment, then it is of utmost importance to gain as much insight as possible into the inner workings of those applications. Have you ever had a chance to look into the cockpit of an airplane or the command center of a nuclear power plant? Both the airplane and the power plant are samples of highly complex systems that deliver mission-critical services. If a plane crashes or a power plant shuts down unexpectedly, a lot of people are negatively affected, to say the least. Thus the cockpit and the command center are full of instruments showing the current or past state of some part of the system. What you see is the visual representation of some sensors that are placed in strategic parts of the system, and constantly collect data such as the temperature...

Overview of this book
Containers enable you to package an application with all the components it needs, such as libraries and other dependencies, and ship it as one package. Docker containers have revolutionized the software supply chain in both small and large enterprises.
Starting with an introduction to Docker fundamentals and setting up an environment to work with it, you’ll delve into concepts such as Docker containers, Docker images, and Docker Compose. As you progress, the book will help you explore deployment, orchestration, networking, and security. Finally, you’ll get to grips with Docker functionalities on public clouds such as Amazon Web Services (AWS), Azure, and Google Cloud Platform (GCP), and learn about Docker Enterprise Edition features. Additionally, you’ll also discover the benefits of increased security with the use of containers.
By the end of this Docker book, you’ll be able to build, ship, and run a containerized, highly distributed application on Docker Swarm or Kubernetes, running on-premises or in the cloud.
