func GetRepositoryTags

func NewReference

func NewReference(ref reference.Named) (types.ImageReference, error)

NewReference returns a Docker reference for a named reference. The reference must satisfy !reference.IsNameOnly().

func ParseReference

func ParseReference(refString string) (types.ImageReference, error)

Types

type Image

type Image struct {
	types.ImageCloser
	// contains filtered or unexported fields
}

Image is a Docker-specific implementation of types.ImageCloser with a few extra methods which are specific to Docker.

func (*Image) GetRepositoryTags

func (i *Image) GetRepositoryTags(ctx context.Context) ([]string, error)

GetRepositoryTags list all tags available in the repository. The tag provided inside the ImageReference will be ignored. (This is a backward-compatible shim method which calls the module-level GetRepositoryTags)

func (*Image) SourceRefFullName

func (i *Image) SourceRefFullName() string

SourceRefFullName returns a fully expanded name for the repository this image is in.

type SearchResult

type SearchResult struct {
	Name        string `json:"name"`
	Description string `json:"description"`
	// StarCount states the number of stars the image has
	StarCount int  `json:"star_count"`
	IsTrusted bool `json:"is_trusted"`
	// IsAutomated states whether the image is an automated build
	IsAutomated bool `json:"is_automated"`
	// IsOfficial states whether the image is an official build
	IsOfficial bool `json:"is_official"`
}

SearchResult holds the information of each matching image It matches the output returned by the v1 endpoint

func SearchRegistry

func SearchRegistry(ctx context.Context, sys *types.SystemContext, registry, image string, limit int) ([]SearchResult, error)

SearchRegistry queries a registry for images that contain "image" in their name The limit is the max number of results desired Note: The limit value doesn't work with all registries for example registry.access.redhat.com returns all the results without limiting it to the limit value
