Functions

func EcosystemsToScanners

func EcosystemsToScanners(ctx context.Context, ecosystems []*Ecosystem) ([]PackageScanner, []DistributionScanner, []RepositoryScanner, error)

EcosystemsToScanners extracts and dedupes multiple ecosystems and returns their discrete scanners

Types

type Coalescer

type Coalescer interface {
	Coalesce(ctx context.Context, artifacts []*LayerArtifacts) (*claircore.IndexReport, error)
}

Coalescer takes a set of layers and creates coalesced IndexReport.

A coalesced IndexReport should provide only the packages present in the final container image once all layers were applied.

type DistributionScanner

type DistributionScanner interface {
	VersionedScanner
	Scan(context.Context, *claircore.Layer) ([]*claircore.Distribution, error)
}

type Ecosystem

type Ecosystem struct {
	Name                 string
	PackageScanners      func(ctx context.Context) ([]PackageScanner, error)
	DistributionScanners func(ctx context.Context) ([]DistributionScanner, error)
	RepositoryScanners   func(ctx context.Context) ([]RepositoryScanner, error)
	Coalescer            func(ctx context.Context) (Coalescer, error)
}

Ecosystems group together scanners and a Coalescer which are commonly used together.

A typical ecosystem is "DPKG" which will use the DPKG package indexer, the "OS-Release" distribution scanner and the "APT" repository scanner.

A Controller will scan layers with all scanners present in its configured ecosystems.

type Fetcher

type Fetcher interface {
	Fetch(ctx context.Context, layers []*claircore.Layer) error
	Close() error
}

Fetcher is responsible for downloading a layer, uncompressing if ncessary, and making the uncompressed tar contents availble for reading.

type LayerArtifacts added in v0.0.14

type LayerArtifacts struct {
	Hash  claircore.Digest
	Pkgs  []*claircore.Package
	Dist  []*claircore.Distribution // each layer can only have a single distribution
	Repos []*claircore.Repository
}

layerArifact aggregates the any artifacts found within a layer

type LayerFetchOpt

type LayerFetchOpt string

LayerFetchOpt tells libindex where to store fetched layers

const (
	// OnDisk - layers will be fetched via HTTP and writen to disk. When scanned the contents will be read from a fd.
	OnDisk LayerFetchOpt = "ondisk"
	// InMem - layers will be fetched via HTTP and writen to the layer's in memory byte array. When scanned the contents will be read from this in memory byte array
	InMem LayerFetchOpt = "inmem"
	// Tee - layers will be fetched via HTTP and written both the layer's in memory byte array and onto disk.
	Tee LayerFetchOpt = "tee"
)

type LayerScanner

type LayerScanner interface {
	Scan(ctx context.Context, manifest claircore.Digest, layers []*claircore.Layer) error
}

LayerScanner is an interface for scanning a set of layer's contents and indexing discovered items into the persistence layer. scanning mechanics (concurrency, ordering, etc...) will be defined by implementations.
