Description: Docker CLI: the open-source application container engine
Docker is a product for you to build, ship and run any application as a
lightweight container
.
Docker containers are both hardware-agnostic and platform-agnostic. This means
they can run anywhere, from your laptop to the largest cloud compute instance and
everything in between - and they don't require you to use a particular
language, framework or packaging system. That makes them great building blocks
for deploying and scaling web apps, databases, and backend services without
depending on a particular stack or provider.
