Hey, Dan.

In response to your question, Docker container shares the host operating system, CPU and memory.

When moving a Docker container to a new environment, you do not need to reinstall dependencies or files.

Docker understands the pain of moving an application between environments.

Therefore, it provides a virtualized environment for the application inside the container.

I hope this response addresses all your questions.

Thank you for finding this article useful.
