What is Docker used for?
The question is about Docker
Docker is used for creating, managing, and running containerized applications. Docker gives a developer the power to package an application and its dependencies, libraries, and configuration into a lightweight, portable container that would run consistently on most environments-from a developer’s machine through a staging and testing environment all the way to production.
Docker is in use with microservices architecture, which very greatly eases the deployment of many services. It also reduces barriers in CI/CD pipelines to faster builds and more frequent updates. Scalability and resource-efficient usage are those features of Docker which make Docker so popular among modern software development teams, DevOps workflows, and cloud-native applications.
