What is Docker Engine?
Docker is software that helps developers. It packages applications in containers. The contents include all needed code, libraries, and settings. Docker solves problems in software building. The containers run on different computers and systems. Docker helps manage the full lifecycle of the containers. So Docker is very useful for modern app development.
Docker makes managing things like images, containers, networks, and volumes simpler. It has a client-server setup. This helps with moving workloads easily. As more businesses use Docker for its efficiency and scalability, it’s important to understand its parts, how to use it, and its benefits. That way, you can use container technology properly.
