What is Containers?
➡️ A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another.
(In simple language,container is a block/box in which we keep our code,all required dependencies.Package those requirements as a one block known as image and we run those image it is called as Container).
What is Docker?
➡️ Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly.
(In simple words, Docker(tool) helps us to make image of our project and run it on Docker engine as a Container.)
Docker containers that run on Docker Engine:
Standard: Docker created the industry standard for containers, so they could be portable anywhere
Lightweight: Containers share the machine’s OS system kernel and therefore do not require an OS per application, driving higher server efficiencies and reducing server and licensing costs
Secure: Applications are safer in containers and Docker provides the strongest default isolation capabilities in the industry
