What is the Grype ? Grype Usage with Examples

grype is a tool developed by Aqua Security that can be used to scan container images for vulnerabilities and other security issues. It is designed to work with a variety of container registry services and supports integration with container orchestration platforms, such as Kubernetes.

grype uses a database of known vulnerabilities to scan container images and identify any vulnerabilities that may be present. It can be run from the command line and provides a web-based user interface for managing and analyzing scan results.

In addition to vulnerability scanning, grype also supports a number of other security features, such as runtime protection, network segmentation, and compliance checks. It is designed to provide a comprehensive security solution for containerized applications and can be used in conjunction with other tools, such as trivy, to improve the overall security posture of your containerized environments.

Scan a container image for vulnerabilities:

grype scan IMAGE_NAME

For example, to scan an image located on Docker Hub, you can use a command like this:

grype scan docker://docker.io/library/alpine:latest

Scan multiple container images at once:

grype scan IMAGE_NAME1 IMAGE_NAME2 ...

For example, to scan two images located on Docker Hub, you can use a command like this:

grype scan docker://docker.io/library/alpine:latest docker://docker.io/library/nginx:latest

Scan an image from a private registry:

grype scan registry://REGISTRY_URL/IMAGE_NAME:TAG

For example, to scan an image located at registry.example.com/myimage:latest, you can use a command like this:

grype scan registry://registry.example.com/myimage:latest

Scan an image and write the results to a file:

grype scan --output results.json IMAGE_NAME

For example, to scan an image located on Docker Hub and write the results to a file named results.json, you can use a command like this:

grype scan --output results.json docker://docker.io/library/alpine:latest

Scan an image and receive notifications via email:

grype scan --notify-email EMAIL_ADDRESS IMAGE_NAME

For example, to scan an image located on Docker Hub and receive notifications at user@example.com, you can use a command like this:

grype scan --notify-email user@example.com docker://docker.io/library/alpine:latest

Scan an image and receive notifications via Slack:

grype scan --notify-slack SLACK_WEBHOOK_URL IMAGE_NAME

For example, to scan an image located on Docker Hub and receive notifications via a Slack webhook, you can use a command like this:

grype scan --notify-slack https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX docker://docker.io/library/alpine:latest

Scan an image and receive notifications via a custom webhook:

grype scan --notify-webhook WEBHOOK_URL IMAGE_NAME

For example, to scan an image located on Docker Hub and receive notifications via a custom webhook, you can use a command like this:

grype scan --notify-webhook https://mywebhook.com/notifications docker://docker.io/library/alpine:latest

Scan an image and enable runtime protection:

grype scan --enable-runtime-protection IMAGE_NAME

Scanning an image and excluding specific vulnerabilities:

grype scan --exclude-vulnerability VULN_1 --exclude-vulnerability VULN_2 IMAGE_NAME

Scanning an image and only including vulnerabilities of a certain severity level or higher:

grype scan --severity SEVERITY_LEVEL IMAGE_NAME

Scanning an image and ignoring unfixed vulnerabilities:

grype scan --ignore-unfixed IMAGE_NAME

Scanning an image and using a custom vulnerability database:

grype scan --db DB_FILE IMAGE_NAME
