Multiple Docker host resources are pooled together to act as one, which enables users to quickly scale up container deployments to multiple hosts. Similar to Hub, Trusted Registry is a repository with an extra layer of control and ownership over container image storage and distribution.ĭocker swarm mode in Docker Engine supports cluster load balancing for Docker. The service touts more than 100,000 publicly available applications, as well as public and private container registries. Docker Compose files define the composition of components in a Docker container.ĭocker Hub is a software-as-a-service tool that enables users to publish and share container-based applications through a common library. Containers created by Docker are called Dockerfiles. The daemon also provides a client-side command-line interface (CLI) for users to interact with the daemon through the Docker application programming interface. The engine creates a server-side daemon process that hosts images, containers, networks and storage volumes. The Docker Engine is the underlying technology that handles the tasks and workflows involved in building container-based applications. Docker consists of various components and tools that help create, verify and manage containers. Versions of Docker for Amazon Web Services (AWS) and Microsoft Azure are available.ĭocker Community Edition is open source, while Docker Enterprise Edition is a commercialized version offered by Docker Inc.
#Dokev platform code
This is different than virtual machines (VMs), which encapsulate an entire OS with executable code on top of an abstracted layer of physical hardware resources.ĭocker was created to work on the Linux platform, but has extended to offer greater support for non-Linux operating systems, including Microsoft Windows and Apple OS X.

Docker images contain all the dependencies needed to execute code inside a container, so containers that move between Docker environments with the same OS work with no changes.ĭocker uses resource isolation in the OS kernel to run multiple containers on the same OS. Each container shares the services of one underlying operating system. Container technology is available through the operating system: A container packages the application service or function with all of the libraries, configuration files, dependencies and other necessary parts and parameters to operate.

How Docker worksĭocker packages, provisions and runs containers. Mirantis acquired the Docker Enterprise business in November 2019.
#Dokev platform software
was formed to support a commercial edition of container management software and be the principal sponsor of an open source version. Docker container technology debuted in 2013 Docker Inc. Meredith Courtemanche, Director of Editorial Trainingĭocker is an open source software platform to create, deploy and manage virtualized application containers on a common operating system ( OS), with an ecosystem of allied tools.
