Question

After a failed Webex notification deploy, an engineer SSHes into the live container and edits Python files to hotfix production. Which 12-factor rule did that break?

Accepted Answer

Build, release, and run are separate stages—do not mutate the running release to invent a new one. — Build stamps the artifact, release marries it to config, run starts processes—like factory, staging dock, and open street. Editing live files collapses those stages into a snowflake nobody can redeploy.

Answer

Dependencies must be undeclared so production can pick packages from the host OS freely.

Answer

Config must be compiled into the image at build so run never reads the environment.

Answer

Logs must be written only to encrypted USB drives attached during the run stage.
