Answer
Secrets live in RAM-backed storage and never appear in layers or logs.
Quick Answer
Docker Secrets (in Swarm mode) distribute secret values to containers as temporary in-memory filesystems mounted at /run/secrets/. They're never written to disk or stored in environment variables. Environment variables for secrets are readable via docker inspect and /proc/self/environ — Secrets avoid both exposure vectors.
