security-docker

Review Docker and container security audit patterns. Use for auditing secrets in layers, port exposure, and non-root users. Use proactively when Dockerfile or docker-compose.yml is present. Examples: - user: "Audit this Dockerfile" → check for secrets in ENV/ARG and non-root USER - user: "Review docker-compose ports" → find accidentally exposed databases - user: "Check for secrets in image history" → audit layers and build artifacts - user: "Optimize Docker security" → implement multi-stage builds and minimal base images - user: "Audit container privileges" → check for privileged: true or docker.sock mounts
