How To Install Docker On Ubuntu

Docker:

Docker is an open source platform that is free and easy to use. It is used to create, implement, and manage containerized applications. Containers simplify distributed programming, making them popular as companies shift to cloud-based development and multi-cloud hybrid setups. It helps developers to bundle programs into containers that can be run and executed in any given environment. Docker is also a toolkit that enables automation by allowing developers to use just one API to create, deploy, operate, change, and pause containers using easy commands. Development of containers can also be done without Docker, but using Docker makes the containerization process simpler, faster, and reliable.
