Overview ¶
Package cataloger provides the ability to process files from a container image or file system and discover packages (gems, wheels, jars, rpms, debs, etc). Specifically, this package contains both a catalog function to utilize all catalogers defined in child packages as well as the interface definition to implement a cataloger.

Functions ¶
func Catalog ¶
func Catalog(resolver source.FileResolver, theDistro *distro.Distro, catalogers ...Cataloger) (*pkg.Catalog, []artifact.Relationship, error)
Catalog a given source (container image or filesystem) with the given catalogers, returning all discovered packages. In order to efficiently retrieve contents from a underlying container image the content fetch requests are done in bulk. Specifically, all files of interest are collected from each catalogers and accumulated into a single request.
Types ¶
type Cataloger ¶
type Cataloger interface {
// Name returns a string that uniquely describes a cataloger
Name() string
// Catalog is given an object to resolve file references and content, this function returns any discovered Packages after analyzing the catalog source.
Catalog(resolver source.FileResolver) ([]pkg.Package, []artifact.Relationship, error)
}
Cataloger describes behavior for an object to participate in parsing container image or file system contents for the purpose of discovering Packages. Each concrete implementation should focus on discovering Packages for a specific Package Type or ecosystem.
func AllCatalogers ¶ added in v0.30.0
func AllCatalogers() []Cataloger
AllCatalogers returns all implemented catalogers
func DirectoryCatalogers ¶
func DirectoryCatalogers() []Cataloger
DirectoryCatalogers returns a slice of locally implemented catalogers that are fit for detecting packages from index files (and select installations)
func ImageCatalogers ¶
func ImageCatalogers() []Cataloger
ImageCatalogers returns a slice of locally implemented catalogers that are fit for detecting installations of packages.
type Monitor ¶
type Monitor struct {
FilesProcessed progress.Monitorable // the number of files selected and contents analyzed from all registered catalogers
PackagesDiscovered progress.Monitorable // the number of packages discovered from all registered catalogers
}
Monitor provides progress-related data for observing the progress of a Catalog() call (published on the event bus).
