Application deployment is cumbersome. Every project requires a specific set of tools and libraries to run correctly. Developers spend hours structuring the perfect environment during the development phase. However, when it's time to shift the project to a new server, the entire effort must take place again.
Docker helps create a portable environment. It is an open-source tool that isolates your project in the form of a container and helps with mobility. It stores your application and environment in the form of images. Since Docker uses the host OS Kernel, these images can be deployed to any new hardware of the same architecture.
