Functions

func EcosystemsToScanners 

func EcosystemsToScanners(ctx context.Context, ecosystems []*Ecosystem, disallowRemote bool) ([]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 ConfigDeserializer added in v0.0.24 

type ConfigDeserializer func(interface{}) error

ConfigDeserializer can be thought of as an Unmarshal function with the byte slice provided.

This will typically be something like (*json.Decoder).Decode.

type ConfigurableScanner added in v0.0.24 

type ConfigurableScanner interface {
	Configure(context.Context, ConfigDeserializer) error
}

ConfigurableScanner is an interface scanners can implement to receive configuration.

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 Indexer added in v0.0.24 

type Indexer interface {
	// IndexPackages indexes a package into the persistence layer.
	IndexPackages(ctx context.Context, pkgs []*claircore.Package, layer *claircore.Layer, scnr VersionedScanner) error
	// IndexDistributions indexes distributions into the persistence layer.
	IndexDistributions(ctx context.Context, dists []*claircore.Distribution, layer *claircore.Layer, scnr VersionedScanner) error
	// IndexRepositories indexes repositories into the persistence layer.
	IndexRepositories(ctx context.Context, repos []*claircore.Repository, layer *claircore.Layer, scnr VersionedScanner) error
	// IndexManifest should index the coalesced manifest's content given an IndexReport.
	IndexManifest(ctx context.Context, ir *claircore.IndexReport) error
}

Indexer interface provide the method set required for indexing layer and manifest contents into a persistent store.

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.

Setter interface provides the method set for required marking events, or registering components, associated with an Index operation.

type Store 

type Store interface {
	Setter

	Kind() string
}

VersionedScanner can be embedded into specific scanner types. This allows for methods and functions which only need to compare names and versions of scanners not to require each scanner type as an argument.
