What is Docker?
Docker is a software platform for developing, deploying, and running containerized applications. Containers are isolated environments that allow developers to package an application’s dependencies and components into a single, self-contained, portable unit, making it easy to transfer them across different development and production environments.
With Docker, developers can create containers that include everything needed to run their application, such as libraries, frameworks, and tools, and then distribute them across different operating systems and platforms. Containers are very lightweight, as they share the same kernel as the host operating system, which means they use fewer resources than traditional virtual machines.
Docker is used in many development and production environments, from small single-container applications to complex multi-container applications running on a cluster of servers. Docker enables developers and system operators to work together more efficiently because containers can run in any environment that has Docker installed, simplifying deployment and reducing downtime.
In addition, Docker also offers tools for building, managing, and distributing container images, allowing developers to easily share their applications with other team members and the open-source community.
In short, Docker is a container platform that makes it easy to develop, deploy, and run applications in different environments. Docker has changed how developers and operations teams work together by providing a highly portable and efficient container platform that reduces downtime and improves collaboration in application development and deployment.
