Docker Installation in Ubuntu 22.02

Docker is a software platform for developing applications based on Containers (lightweight execution environments) that share the operating system kernel but in isolation. In Unix and Linux-based systems, Containers have been utilized for some time, however, when Docker was deployed in the market in 2013, it became easier for the developers to bundle their applications in such a way that it is created once and can be executed anywhere.
