Why Docker
Docker is a popular platform that allows developers to create, deploy, and run applications in a containerized environment. Essentially, it solves the problem of dependency management, allowing developers to easily package their applications with all the required libraries and dependencies in a single container. This makes it easier to deploy applications across different environments without worrying about compatibility issues.
One of the great things about Docker is its ability to create isolated environments, known as containers, which allow developers to run applications with consistent behaviour across different platforms. This means that developers can develop and test their applications on their local machines and then deploy them to production environments with confidence that they will behave the same way.
