And transfers those headaches to your security and ops teams.

There's a new RCE vulnerability against node-sprintf version
1.1.0. Where is it running? Is it safe to keep running your
containers until the weekend, or do you need to replace some
today?

You've got a display inconsistency in floating point
representation. Which of your deployed containers has it? What
libraries were they using? If it's a one-line fix, can you
insert the patched library on every container or do you need to
rebuild every container?

Your QA team tested version 10.4.2, but node:latest is pulling
in 10.4.2a since some point after your got it tested but before
you deployed. Does your deployment process guarantee the version
number that you tested is the version you deployed?

All of those problems are solved by configuration management and
deployment systems, and containers at best obfuscate them.
