Docker

Docker is a containerization platform that allows you to package, ship and run any application as a lightweight and portable container.

The benefits of using Docker include faster deployment times, improved code reuse, and easier collaboration among developers. Docker also provides a consistent development environment across different machines and operating systems.

To get started with Docker, you'll need to install the Docker Engine on your machine. You can download the Docker installation package from the official Docker website. Once installed, you can use the Docker CLI to create and manage containers.

A Docker container is a lightweight and portable environment that runs an application, whereas a virtual machine is a complete operating system running on top of another OS. Containers are faster and more efficient than VMs because they share the host's kernel and don't require a separate OS instance.

You can manage Docker containers using the Docker CLI or the Docker web interface, called Docker Desktop. With Docker CLI, you can create, start, stop, pause, and delete containers using commands such as `docker run`, `docker ps`, `docker stop`, etc.

Docker images are templates used to build Docker containers. Images contain the application code, dependencies, and settings required to run an application. You can use Docker images as a starting point for creating your own custom containers or to deploy existing applications in a consistent environment.
