Not true. Managing OS images is the killer app for containers.
Containers power the Heroku platform and it supports millions of apps by containerizing OS images.
When both the bamboo stack and cedar stack were available, we would:
Run a base AMI and update it frequently for kernel, security and performance updates.
Download a bamboo (Debian) OS layer
Dowbload a cedar (Ubuntu 12.04) OS layer.
Layer app slugs on top of which ever stack the customer wanted.
This was amazing for long term support of apps and backwards compatibility.
There are infinitely more rails apps out there that deeply depend on the OS layer than there are static binary apps.
Docker deserves and gets all its credit for making this technique available and easy for everyone.
