# Docker Docker is a platform that simplifies the process of developing, shipping, and running applications by using containers. Containers are isolated environments that package software, libraries, and configuration files, allowing applications to run consistently across different environments. Docker enables the separation of applications from infrastructure, facilitating quick software delivery and efficient management. * **Dockerfile**:-A Dockerfile is a script of instructions to build a Docker image. It specifies the base image, sets up the environment, installs dependencies, copies files, and defines the command to run the application. It's essential for automating the creation and deployment of Docker containers. Create files and Build Docker [images](/neevcloud-guide/neevcloud-knowledgebase/docker/some-best-practices-for-using-docker-in-application-development-include/create-a-docker-file-and-using-docker-file-build-images.md). * **DockerBuild**: Docker Build is a feature of Docker Engine that allows users to create Docker images from a set of instructions defined in a text file called a Docker file. These instructions specify how to build the image, including steps like copying files, installing dependencies, and setting up the environment needed to run an application. * **Docker container** is a lightweight, standalone, executable package that includes everything needed to run a piece of software: code, runtime, system tools, libraries, and settings. It's isolated from the host system, ensuring consistent and reliable performance across different environments.
