I thought I understood Docker until I saw the BusyBox docker image

Question

I thought I understood Docker. I understood it as a way to package up software with lots of dependencies..to basically create a little world where absolutely everything is t

Answer 1

But I don't understand at all why this image exists, which makes me think that I don't actually understand why Docker exists. What is the point of a BusyBox docker image?

I just started using BusyBox with docker, but so far it has been convenient to use with the --rm command to create unsaved instances with common built in utilities like ping, and yeah just ping so far :/

docker container run --rm -it --network [network_name] busybox

and then all those utilities in BusyBox are available on that docker custom network and instantly destroyed when you exit the BusyBox CLI
