Overview

This script minimizes the size of a trivy report by factoring out vulnerability details, so that details for common vulnerabilities are not duplicated for each instance of that vulnerability.

Functions

func ConvertTrivyResultsToImageReport

func ConvertTrivyResultsToImageReport(images []models.Image, reportResultByRef map[string]*models.TrivyResults, ignoreErrors bool) []models.ImageReport

ConvertTrivyResultsToImageReport maps results from Trivy with metadata about the image scanned.

func FetchLastReport

func FetchLastReport(ctx context.Context, host, org, cluster, token string) (*models.MinimizedReport, error)

FetchLastReport returns the last report for Trivy from Fairwinds Insights

func GetImages

func GetImages(ctx context.Context, namespaceBlocklist, namespaceAllowlist []string) ([]models.Image, error)

GetImages returns the images in the current cluster.

func GetImagesToReScan

func GetImagesToReScan(images []models.Image, lastReport models.MinimizedReport, imagesToScan []models.Image, maxScans int) []models.Image

func GetMatchingImages

func GetMatchingImages(baseImages []models.ImageDetailsWithRefs, toMatch []models.Image, isRecommendation bool) []models.ImageDetailsWithRefs

func GetNewestVersions

func GetNewestVersions(ctx context.Context, repo, tag string) ([]string, error)

GetNewestVersions returns newest versions and newest version within same major version

func GetNewestVersionsToScan

func GetNewestVersionsToScan(ctx context.Context, allReports []models.ImageReport, imagesToScan []models.Image) []models.Image

func GetRecommendationKey

func GetRecommendationKey(repoName, specific string) string

func GetSpecificToken

func GetSpecificToken(tag string) string

func GetUnmatchingImages

func GetUnmatchingImages(baseImages []models.ImageDetailsWithRefs, toMatch []models.Image, isRecommendation bool) []models.ImageDetailsWithRefs

func Minimize

func Minimize(images []models.ImageReport, lastReport models.MinimizedReport) models.MinimizedReport

Minimize compresses the format of the Trivy report to de-duplicate information about vulnerabilities.

func ScanImage

func ScanImage(extraFlags, pullRef string) (*models.TrivyResults, error)

ScanImage will scan a single image with Trivy and return the results.

func ScanImages

ScanImages will download the set of images given and scan them with Trivy.

func Sort

func Sort(versions []*semver.Version)

Sort sorts the given slice of Version

func UpdateOwnersReferenceOnMatchingImages

func UpdateOwnersReferenceOnMatchingImages(baseImages []models.ImageDetailsWithRefs, clusterImages []models.Image) []models.ImageDetailsWithRefs
