It’s really simple, it’s a container containing a virtual os, which runs a browser and a webserver to run the app. The app connects to several external api services to do it’s thing.
It’s like, really simple!
I‘m very scared that this might actually be the case in some apps out there.
If they’re running a virtual OS in a container, they’re doing it very wrong. Containers and VMs are quite different, even on a Windows host.
I‘m not sure I understand. At least docker containers have their own os, mostly alpine linux. Dunno if that applies to other apllications.
Nah, a container isn’t running nearly as much as an entire OS. Not by a long shot. The Kernel isn’t there at all and the entire device stack is gone. Most don’t even have an init system running like systemd. They’re closer to a chroot in a single terminal than running an entire OS.
The OS flavor in a container is mostly about what flavor of supporting tools are available inside the container. Almost everything else is a thin wrapper making calls in to your host OS or container services.
