Static Docker/container security audit across 6 dimensions (K1-K6): base image provenance and pinning, privilege and runtime hardening, secret and build-context hygiene, image minimalism and attack surface, known-vulnerability scan (Trivy/Grype), and compose/orchestration hardening. Static-first — parses Dockerfile, Containerfile, and docker-compose (incl. override/merge files) with zero Docker and zero network; the CVE dimension (K5) runs Trivy/Grype only when present, else degrades to N/A.…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# zuvo:container-audit Audit container artifacts (Dockerfile, Containerfile, docker-compose) as **code** for security defects — running as root, mutable `:latest` bases, secrets baked into layers, bloated attack surface, known CVEs, and `docker.sock` mounts. Single-pass, read-only. **When to use:** before shipping a Dockerized service, after editing a Dockerfile or compose file, periodic container hardening review, pre-deploy gate. **When NOT to use:** auditing the **live Docker daemon** on a remote host over SSH (`zuvo:infra-audit` IS9); Docker **build speed / cache** in CI (`zuvo:ci-audit` CI8); application-code vulnerabilities (`zuvo:security-audit`). ## Mandatory File Loading Read every file below before starting. Print the checklist. ``` CORE FILES LOADED: 1. ../../shared/includes/codesift-setup.md -- [READ | MISSING -> STOP] 2. ../../shared/includes/env-compat.md -- [READ | MISSING -> STOP] 3. ../../shared/includes/report-output-location.md -- [READ | MISSING -> STOP] 4. ../../shared/includes/severity-vocabulary.md -- [READ | MISSING -> STOP] 5. ../../shared/includes/run-logger.md -- [READ | MISSING -> STOP] …

How to install
mdr add greglas75/zuvo/container-audit@sha256:ea189ff50b0b7d97The line at the top of this page pins the label git:20261017.3e0c4c2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
