What is a container?

[Schumann523]

What is a container? I have researched this topic, and I have come across many definitions that I have found confusing.
Looking at it from the point of view of a PC, isn't a container essentially just an application?
Any input is appreciated. Thanks in advance.

Container - Containers are a form of operating system virtualization, its can be installed on the switch or any device which can support in the Cisco devices.

Cisco Uses Container builds part of many solutions :

Not sure what context you looking for here. 

If you looking at PC, it is another Virtual device, it can be Docker or VM or any other small form of software.

From Docker's definition, a Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings.

While 'application' description is somewhat correct, it doesn't quit convey 'code, runtime, system tools, system libraries and settings.'

When you look at containers that exist for an entire Linux distribution like Ubuntu, I think you get the bigger picture.

It is true that containers are more like an application, in that they typically won't have all the overhead that an entire guestVM would.

Hope that helps.

This is a cute and funny way to explain what is a container and how kubernetes works: https://www.youtube.com/watch?v=4ht22ReBjno

this is the docker's website definition:

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. A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings.
