This is the best book to learn Docker from zero. Docker is the virtualization architecture from the future!
Dockers is a command line program, a background daemon, and a suite of remote services that take a logistical approach to solve common software problems and simplify your installation, execution, publishing, and removal software. To do this, use a UNIX technology called containers.
Historically, UNIX-based operating systems have used the term prison to describe a modified execution time of a program that prevents that program from accessing protected sources. Since 2005, after the launch of the Sun Solaris 10 and Solaris 10 tanks, the tank has become the preferred term for such runtime. The goal, which was only to prevent access to protected resources, was to isolate the process from all resources unless explicitly authorized. The use of containers has been a recommended practice for a long time. But the manual construction of a container can be difficult and just plain wrong. This challenge put them out of reach of some, and misconfigured containers inspired others to have a false sense of security. We need a solution to this problem, and Docker helps. Any software that works with Docker runs in the container. Docker uses existing tank motors to ensure consistent tanks are built in accordance with best practices. This puts greater certainty in the reach of everyone. With Docker, customers get low-cost containers. As Docker and his tanks improve, you get the best and latest jailbreak features. Instead of following the fast-paced and highly technical world of building powerful prison prisons, you can let Docker do it for you. This will save you time, money and give you peace of mind.
Containers are not virtualization. Without Docker, organizations often use hardware virtualization (also known as virtual machines) to provide isolation. Virtual machines provide virtual hardware into which the operating system and other programs can be installed. It takes a lot of time (often minutes) to create and require a significant overload of resources as they run a full copy of the operating system except the software you want to use. Unlike virtual machines, Docker containers do not use hardware virtualization. Programs running in Docker containers communicate directly with the Linux host kernel. As there is no additional layer between the program running inside the container and the computer's operating system, resources are not wasted by using redundant software or simulating virtual hardware. This distinction is important. Docker is not virtualization technology. Instead, it helps you use container technology that is already integrated into your operating system.
With Docker by Jordan Lioy you will learn:
• The basics - the theory behind Docker
• Extensive coverage of Docker architecture
• Deep dive into core concepts such as images and containers
• How Docker can organize your projects
• Networking, volumes, and security
• Docker Certified Associate (DCA) coverage
And much, much more, with a lot of examples to help you understand and implement every solution.
