I can’t seem to wrap my head around (Docker) containers and especially their maintenance.
As I understand it, containers contain a stripped-down OS that shares some resources with the host?
Or is it more like a closed-off part of the file system?

Anyway, when I have several containers running on a host system,
Do I need to keep them all updated separately? If so, how?
Or is it enough to update the host system, and not worry about the containers?

    Container update is not Docker’s concern. Docker is proxy between your Container and OS. So if you want keep your container up to date you need external process. Can be achieved with container orchestration tool like Kubernates
