Coalescer

A coalescer must compute the final contents of a manifest given the artifacts found at each layer.

package indexer // import "github.com/quay/claircore/indexer"

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.

package indexer // import "github.com/quay/claircore/indexer"

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.

package indexer // import "github.com/quay/claircore/indexer"

type LayerArtifacts struct { Hash claircore.Digest Pkgs []*claircore.Package Dist []*claircore.Distribution // each layer can only have a single distribution Repos []*claircore.Repository Files []claircore.File } LayerArifact aggregates the artifacts found within a layer.

A `Coalsecer` implementation is free to determine this computation given the
artifacts found in a layer. A `Coalescer` is called with a slice of
`LayerArtifacts` structs. The manifest's layer ordering is preserved in the
provided slice.
