A Docker image is a type of file. These types of files are mainly composed of different layers that are used to divide the code in the Docker contain.
A docker image is a file, constituted of recurring layers, applied to complete code in a docker container and an image is built from the instructions for an executable version of the application, which depends on the host OS kernel. When the client runs an image, it becomes one or multiple instances of that container. Docker, an open-source OS-level virtualization software platform originally designed for Linux, Windows, and macOS will sometimes move software from one host computer to another will cause issues due to the dependencies the software may have had. Docker will do resource isolation characteristics in the OS kernel, similar to cgroups in Linux, to run various independent containers on the corresponding OS.
