Using Docker virtual containers to launch services

Abstract

Docker is a virtualization tool that allows developers and system administrators to run applications and services in containers isolated from each other and from the guest operating system. Docker containers, unlike other virtualization tools, work directly with the host machine hardware, which is good for system resource consumption. Containers run from prebuilt images. The ability to collect all dependencies and application data in an image allows you not to worry about compatibility with the systems in which the container will run. The independence of containers from each other allows you to run entire groups of related services, in which a change of version or data in one of the containers does not affect the functioning of the rest of the group.
