In June 2015, Docker led the formation of the OCI (Open Container Initiative) organization, which aims to establish a common standard around containers. Later, in order to achieve complex scenarios such as cross-platform, Docker pulled out the libcontainer project, encapsulating operations on namespace and cgroup in the libcontainer project, supporting different platform types. For example, the first community release in June 2018 was 18.06.0-ceĮstablished in 13 years and starting in 15 years, it has experienced rapid development.īefore Docker 1.8, use LXC Docker encapsulates LXC's complex containers and simplifies their creation and use as a set of commands.

Starting in the first quarter of 2017, the Docker version number follows the YY.MM-xx format, similar to projects such as Ubuntu.

The monthly Community Edition also releases the monthly edition via Edge.

The community version will provide 4 months of support, while the enterprise version will provide 12 months of support

Each quarter (1-3,4-6,7-9,10-12), a stable version (Stable) is released for both the Enterprise and Community editions.

There are two major versions of the Docker engine: Enterprise (EE) and Community (CE).

Provides lightweight virtualization where containers are virtual spaces in one host machine, isolated from each other and completely independent You can start the image as a container and manage (start, stop, delete) the life cycle of multiple containers.Ĭontainer containers are isolated from each other, and each container can set a resource limit

Solve environmental dependencies in software delivery based on lightweight featuresĪpplication code and run-dependent environments can be packaged and mirrored as delivery media for deployment across environments

What is a dockerĪ CS-based software product that provides lightweight virtualization capabilities based on the operating system core. This removes the space occupied by the kernel and the time required to run it, making the container extremely lightweight and fast. Common VMware's Workstation, ESXi, Microsoft's yper-V, or Sijie's XenServer.Ĭontainer Runtime: Manages multiple containers through the Linux kernel virtualization capability, which share a set of operating system cores. Hypervisor: An intermediate software layer that runs between the underlying physical server and the operating system, allowing multiple operating systems and applications to share hardware.

To facilitate the creation and management of these containers, dotCloud developed a set of internal tools that were later named "Docker". Know dockerĪ lightweight, efficient virtualization capability is requiredĭocker, based in San Francisco and originally known as dotCloud, leverages Linux Container Technology (LXC), which isolates and restricts resources within the operating system. Through this chapter, you will know the concept and basic operation of docker, learn to build your own business image, and master the communication of Docker's most commonly used bridge network mode by grabbing packages.
