What tasks and challenges is the Docker platform designed for?

Docker is designed to solve problems related to deploying and managing applications across different environments. The main tasks and challenges it helps to overcome:

• Environment isolation: Docker containerizes applications along with all their dependencies, preventing conflicts between libraries and settings on different machines.
• Portability: Docker images can be run on any system with Docker installed, simplifying the transfer of applications between development, testing, and production.
• Simplification of CI/CD: Containers allow standardizing the build and deployment process, making it more predictable and automatable.
• Lightweight: Unlike virtual machines, containers use host resources more efficiently, enabling more applications to run on a single server.

Example: instead of configuring environments with the required versions of Python, libraries, and databases on each computer, you can create a Docker image with a ready environment and run it everywhere in the same way.
