It is a lightweight runtime system and the underlying client-server technology that creates and manages containers.ĭocker Engine consists of three components: The Docker Engine (DE) is installed on the host machine and represents the core of the Docker system. The tool consists of multiple components, each playing an important role in the platform. Since then, Docker has been drawing attention of many technology providers and high-profile companies. However, many developers showed great interest specifically for the underlying technology of DotCloud - software containers. Before focusing on containers, the project started as a Platform as a Service solution called DotCloud, in 2008.

A version control system for an application.ĭocker was introduced as an open-source project in March 2013 at P圜on.

A cost-effective alternative to virtual machines.

Developing highly portable workloads that can run on multi-cloud platforms.

Streamlining the development lifecycle and supporting CI/CD workflows.

Standardizing environments to ensure consistency across development and release cycles.

Isolating and segregating applications.

Running multiple workloads on fewer resources.

To maximize container performance, make sure to implement Docker container best practices. However, you can grant the instance root capabilities by running a container in privileged mode. Note: Containers do not have direct communication with the host. For step-by-step instructions, check out: The most crucial distinction is that Docker containers are lighter, faster, and more resource efficient than virtual machines. Since Docker utilizes virtualization to create containers for storing apps, the concept may seem similar to virtual machines. Although both represent isolated virtual environments used for software development, there are important differences between containers and VMs. Packaging apps into isolated environments (containers) also makes it easier to develop, deploy, maintain, and use applications. By making the software system agnostic, developers don’t have to worry about compatibility issues. It is mainly used as a software development platform for developing distributed applications that work efficiently in different environments.

Docker is an open-source containerization platform used for developing, deploying, and managing applications in lightweight virtualized environments called containers.
