container
A container runs a process with a packaged filesystem and configured isolation.
Use this when A service starts differently across development and deployment environments.
without the term
“It works on my Mac but fails on the server because of different versions of stuff. Can you package it so it runs the same everywhere?”
with the term · How do you ask a model for container?
Containerize this service with pinned build inputs and a non-root runtime where supported. Verify startup and shutdown without undeclared host dependencies.
What is container?
A container image packages the app with its dependencies and filesystem, so it runs the same everywhere. Configuration and persistent data are supplied from outside.
Why does container matter when vibe coding?
A successful local image can still depend on unrecorded host files.
How do you do container?
Build a reproducible image and test startup, shutdown, configuration, and persistent storage explicitly.
What goes wrong with container?
Assuming a container alone supplies durable storage or a complete security boundary.
