What is the Difference Between Docker and Container? with Proper Definition and Brief Explanation

The main difference between Docker and container is that a Docker is a platform for creating, running and managing software containers while a container is a lightweight software that provides virtualization of the operating system to run applications and their dependencies in isolated processes. means.

A container is software that bundles its own tools, libraries, and configuration files. There can be multiple containers running on a single operating system kernel. Also, it is light than a virtual machine. On the other hand, Docker is a software that helps to run and manage containers.

What is a container

Containers are an abstraction in the application layer that combines code and dependencies. Virtualize the operating system. Also, it is possible to run multiple containers on the same machine and share the OS kernel with other containers and each container works as isolated processes. Also, a container is lightweight and requires minimal storage space (megabytes). It also requires minimal boot time.

Furthermore, a container provides multiple advantages. Reduces IP management resources and requires minimal code to transfer, migrate, load workloads. In general, a container provides a portable operating environment for development, testing, and deployment.

what is a docker

A docker is a software platform for managing containers. Docker’s main goal is to help developers easily develop applications and ship them to a container for deployment at any time. Also, there are several components available in Docker. Docker for Mac runs the Docker container on Mac OS. Similarly, there are Linux and Windows versions that allow Docker to run on their respective platforms. The Docker engine allows you to create Docker images and create Docker containers. Docker hub is a registry that hosts multiple Docker images. Additionally, Docker Compose helps define applications using multiple Docker containers.

Docker provides multiple benefits. It allows team members in different units to make tasks such as development, QA, etc. much easier. Furthermore, it is possible to deploy the Docker container on a physical device, virtual machine or cloud. Furthermore, it is easily scalable and provides a default isolation capability to improve security.

Difference between Docker and Container


Docker is a software platform for creating, deploying, and managing virtualized application containers on a common operating system with an ecosystem of allied tools. In contrast, Container is a lightweight alternative to full machine virtualization that involves encapsulating an application with its own operating environment.


Docker works as a container management service. However, Container is software that packages code and all of its dependencies so that applications can run quickly and reliably from one computing environment to another. This is the basic difference between Docker and Container.


Docker improves scalability, improves security, and makes the development process easier. The container, on the other hand, improves operational efficiency, productivity, and version control. , This is another difference between Docker and Container.


In conclusion, the basic difference between Docker and Container is that Docker is a platform for building, running, and managing software containers, while a container is a lightweight software that provides virtualization of the operating system to run applications and their dependencies in isolated processes. means..
