Configuration in MegaLinter

Enable grype by adding REPOSITORY_GRYPE in ENABLE_LINTERS variable
Disable grype by adding REPOSITORY_GRYPE in DISABLE_LINTERS variable

Variable	Description	Default value
REPOSITORY_GRYPE_ARGUMENTS	User custom arguments to add in linter CLI call Ex: `-s --foo "bar"`
REPOSITORY_GRYPE_COMMAND_REMOVE_ARGUMENTS	User custom arguments to remove from command line before calling the linter Ex: `-s --foo "bar"`
REPOSITORY_GRYPE_CLI_LINT_MODE	Override default CLI lint mode ⚠️ As default value is project, overriding might not work - `file`: Calls the linter for each file - `list_of_files`: Call the linter with the list of files as argument - `project`: Call the linter from the root of the project	`project`
REPOSITORY_GRYPE_PRE_COMMANDS	List of bash commands to run before the linter	None
REPOSITORY_GRYPE_POST_COMMANDS	List of bash commands to run after the linter	None
REPOSITORY_GRYPE_UNSECURED_ENV_VARIABLES	List of env variables explicitly not filtered before calling REPOSITORY_GRYPE and its pre/post commands	None
REPOSITORY_GRYPE_CONFIG_FILE	grype configuration file nameUse `LINTER_DEFAULT` to let the linter find it	`.grype.yaml`
REPOSITORY_GRYPE_RULES_PATH	Path where to find linter configuration file	Workspace folder, then MegaLinter default rules
REPOSITORY_GRYPE_DISABLE_ERRORS	Run linter but consider errors as warnings	`false`
REPOSITORY_GRYPE_DISABLE_ERRORS_IF_LESS_THAN	Maximum number of errors allowed	`0`
REPOSITORY_GRYPE_CLI_EXECUTABLE	Override CLI executable	`['grype']`

Behind the scenes

How are identified applicable files

If this linter is active, all files will always be linted

How the linting is performed

grype is called once on the whole project directory (project CLI lint mode)

filtering can not be done using MegaLinter configuration variables,it must be done using grype configuration or ignore file (if existing)
VALIDATE_ALL_CODEBASE: false doesn't make grype analyze only updated files

Example calls

grype dir:.

Help content

A vulnerability scanner for container images, filesystems, and SBOMs.

Supports the following image sources:
    grype yourrepo/yourimage:tag             defaults to using images from a Docker daemon
    grype path/to/yourproject                a Docker tar, OCI tar, OCI directory, SIF container, or generic filesystem directory

You can also explicitly specify the scheme to use:
    grype podman:yourrepo/yourimage:tag          explicitly use the Podman daemon
    grype docker:yourrepo/yourimage:tag          explicitly use the Docker daemon
    grype docker-archive:path/to/yourimage.tar   use a tarball from disk for archives created from "docker save"
    grype oci-archive:path/to/yourimage.tar      use a tarball from disk for OCI archives (from Podman or otherwise)
    grype oci-dir:path/to/yourimage              read directly from a path on disk for OCI layout directories (from Skopeo or otherwise)
    grype singularity:path/to/yourimage.sif      read directly from a Singularity Image Format (SIF) container on disk
    grype dir:path/to/yourproject                read directly from a path on disk (any directory)
    grype sbom:path/to/syft.json                 read Syft JSON from path on disk
    grype registry:yourrepo/yourimage:tag        pull image directly from a registry (no container runtime required)
    grype purl:path/to/purl/file                 read a newline separated file of purls from a path on disk

You can also pipe in Syft JSON directly:
  syft yourimage:tag -o json | grype

Usage:
  grype [IMAGE] [flags]
  grype [command]

Available Commands:
  completion  Generate a shell completion for Grype (listing local docker images)
