Assess Docker Image Security with cnspec

Use cnspec to scan Docker images, containers, and Dockerfiles for security misconfigurations, CVEs, and end of life operating systems using the built in Mondoo security policies or your own custom policies.

Docker Image Scan

Dockerfiles​

Scan Dockerfiles to reveal security issues before they reach production.

Scan a single Dockerfile, substituting the path a name of the file for FILEPATH:

cnquery scan docker file FILEPATH

Find nested Dockerfiles within a directory, substituting the directory path for PATH:

cnquery scan docker file PATH

Docker images​

Use cnspec to scan Docker images in public or private container registries using their registry name:

cnspec scan docker ubuntu:latest
cnspec scan docker elastic/elasticsearch:7.2.0
cnspec scan docker gcr.io/google-containers/ubuntu:22.04
cnspec scan docker registry.access.redhat.com/ubi8/ubi

If the Docker agent is installed, you can scan images by their id:

cnspec scan docker docker-image-id

Docker containers​

Scan a running or stopped Docker container by the container ID:

cnspec scan docker docker-container-id
note

You can only scan Docker containers if the Docker engine is installed.

Manage cnspec providers for containers​

Providers are the components of cnspec that allow it to evaluate specific platforms. To learn how to manage cnspec providers most efficiently for containers, read Manage cnspec Providers.
