low

apk add Without --no-cache

Detects RUN instructions using Alpine Linux's apk add command without the --no-cache flag, which unnecessarily increases Docker image size by 2-5 MB.

critical

Docker Socket Mounted as Volume

Detects VOLUME instructions that mount the Docker socket, giving a container full control over the host's Docker daemon, equivalent to unrestricted root access.

info

Deprecated MAINTAINER Instruction

Detects usage of the deprecated MAINTAINER instruction, which has been deprecated since Docker 1.13 in favor of LABEL instructions with standardized OCI metadata keys.
