Docker is a platform for creating, shipping, and operating applications within containers. Containers enable programmers to bundle an application and its dependencies $($e$.$g$.,$ frameworks, libraries$)$ into a standardised development unit. This ensures the programme runs smoothly and consistently across multiple computer environments, from development to testing and production.Docker containers are extremely portable and may run on any system, regardless of infrastructure. Virtual machines must be compatible with the host hardware and are typically confined to specific virtualization platforms. $$ Due to limitations in the Windows $7$ operating system, executing Linux containers is not directly supported. Windows $7$ lacks the capability that Linux offers. Containers rely on resources provided by the host operating system's kernel. Docker Toolbox and Docker Machine create a thin Linux virtual machine $($VM$)$ on your Windows $7$ PC$,$ allowing you to run Linux containers indirectly. $$ Virtualization software, such as VMware Wo
