> Containers never solved the permission model. They solved the packaging and idempotency problem Disagree. Containers are primarily about separation and decoupling. Multiple services on one server often have plenty of ways to interact and see each other and are interdependent in non-trivial ways (e.g. if you want to upgrade the OS, you upgrade it for all services together). Services running each in its own container provides separation by default. OTOH, containers as a technology has nothing to do with packaging, reproducibility and deployment. Just these changes arrived together (e.g. with Docker) so they are often associated, but you can have e.g. LXC containers that can be managed in the same way as traditional servers (by ssh into a container).
