To the end user, this looks exactly the same as "updating".

If replacing a "regular" program that's just an executable and then restarting it is "updating", why isn't it the same for containers? Except theb the "executable" is the container image and the "running program" is the actual container.

Another level would be "immutable" distributions: would you say they don't "update", they just "download a fresh image to boot from"?

It is exactly the same thing except you as the user are wrong for wanting to "update an application"

Docker is weird and they sure do have some Opinions. I try to avoid it.
