1. Break Down the Problem

To determine what Docker is primarily used for, we should consider the definitions of each provided option and how they relate to Docker's core functionalities.

2. Relevant Concepts

• Containerization: This refers to the packaging of software applications and their dependencies into isolated units called containers, which can run on any system that supports Docker.
• Continuous Integration: This is a practice in software development that involves merging all developer working copies to a shared mainline several times a day.
• Project Management: This involves planning, execution, and closing of projects, which is not directly related to Docker's functionalities.
• Version Control: This refers to the management of changes to documents, computer programs, and other collections of information.

3. Analysis and Detail

Docker plays a crucial role in the concept of containerization by allowing developers to automate the deployment of applications inside lightweight containers. This allows for consistency across different computing environments and alleviates the "it works on my machine" problem.

4. Verify and Summarize

Among the options presented, continuous integration, project management, and version control do not encapsulate the primary use of Docker. Docker's main functionality aligns with containerization.

Final Answer

Docker is primarily used for: Containerization.
