Sometimes, confusion between Docker images and containers could arise due to disc space. Therefore, the execution and building of containers are performed by a Docker daemon. A Docker host can either be a physical or a virtual machine running the OS of the host. A container that shifts between different Docker environments using the same OS will work without any change as the image has all the dependencies needed for executing the code.ДЄlso, containers are different from virtual machines, which cover an entire OS with the code on top of the abstraction layer from various hardware resources. Moving software from host machines to host machines sometimes lead to different issues due to the software dependencies. These are templates created by Docker file and arranged in layers, where each layer is dependent on the other. A Docker image is a series of processes set in a Docker file. In simple words, Docker facilitates smooth application development and deployment.Дocker creates remote virtualized environments for building, testing, and deploying various applications. Docker image is a read-only-template created by using the open-source software platform, Docker, designed to run on Windows, macOS, and Linux. It is a standalone, lightweight, and executable software package, which includes all attributes (i.e., code, system tools, libraries, runtime, etc.) required to run an application.Дocker image helps in the convenient packaging of applications as well as pre-configured servers, which can be used privately or even publicly with other users. What is a Docker Image?ДЄ Docker image includes a set of instructions used to create a container for a Docker platform.
