What is Docker?
A tool called Docker is intended to make it simpler to develop, distribute, and run applications using containers. A container is a package that includes the application code, libraries, dependencies, and runtime that an application needs to function.
A programme can be packaged with all of its dependencies and operate in any environment thanks to containers. This makes it easier to develop, test, and deploy applications, as you can be sure that the application will run the same way regardless of where it is deployed.
Docker provides a platform for developers to build, package, and distribute containerized applications. It also provides tools for running and managing containers, including the Docker Engine, which is a runtime that executes containers.
Docker is widely used in the software industry, and it is a key component of many modern software developments and deployment pipelines. It is particularly useful for microservices architectures, where applications are divided into small, independent components that can be developed and deployed independently.
It is primarily used as a platform for software developers to create distributed applications that operate effectively in various settings. Developers can avoid worrying about compatibility problems by making the software system independent. Applications can be developed, deployed, maintained, and used more easily if they are packaged into isolated environments (containers).
Uses of Docker include:
- utilizing fewer resources to run several workloads.
- Applications separation and isolation.
- establishing standards for environments to ensure consistency across release and development cycles
- CI/CD workflow assistance and development lifecycle optimization.
- Creating workloads that are extremely portable and can run across several clouds.
