TMA-DOCKER-4.9
Ensure secrets are not stored in Dockerfiles
Description
Do not store any secrets in Dockerfiles. Docker images are not opaque and contain information about the commands used to build them. As such secrets should not be included in Dockerfiles used to build images as they will be visible to any users of the image. Reported as a manual review item: the audit needs a site-specific judgement.
