Dockerfile Risk Scanner
Scan Dockerfiles for security misconfigurations, hardcoded secrets and best-practice violations
Paste a Dockerfile and the scanner flags risky patterns such as running as root, unpinned base images, hardcoded secrets and unnecessary packages, with a short explanation of why each matters and how to correct it. More free security tools.
Most Dockerfile security issues come from a handful of repeatable mistakes: running the container process as root (the default if you never add a USER instruction), pulling a base image by a floating tag like latest instead of a pinned digest or version, baking secrets or API keys into ARG/ENV instructions where they persist in the image history, and leaving package manager caches or build tools in the final layer.
This scanner parses your Dockerfile line by line and flags these patterns, explaining why each one matters — for example, a leaked secret in an ENV instruction is recoverable from any image layer with docker history, even if it's removed in a later instruction.
