Types

type BundleCache 

type BundleCache interface {
	// GetBundle returns a bundle for the given image. An error is
	// returned if the bundle cannot be retrieved or the data is
	// corrupted.
	GetBundle(img string) (*operator.Bundle, error)
	// SetBundle caches a bundle for the given image. An error
	// is returned if the bundle cannot be cached.
	SetBundle(img string, bundle operator.Bundle) error
}

BundleCache provides a cache of OPM bundles which are referenced by bundleImage name.

	// contains filtered or unexported fields
}

func NewBundleCacheImpl added in v0.15.0 

func NewBundleCacheImpl(opts ...BundleCacheImplOption) *BundleCacheImpl

}

func NewIndexExtractor 

func NewIndexExtractor(opts ...IndexExtractorOpt) *DefaultIndexExtractor

NewIndexExtractor - takes a variadic slice of options to configure an index extractor and applies defaults if no appropriate option is given.

func (*DefaultIndexExtractor) ExtractAllBundleImages

	// extract all bundles from indexImage, for all packages
	ExtractAllBundles(ctx context.Context, indexImage string) ([]operator.Bundle, error)
}

Extractor - utilizes both the indexExtractor and bundleExtractor to first extract all bundleImages from an indexImage, and then extract all the corresponding bundles from those underlying bundleImages.

type IndexCache 

type IndexCache interface {
	// GetBundleImages retrieves bundles image names for a particular
	// indexImage and package combination.
	GetBundleImages(indexImage string, pkgName string) ([]string, error)
