Functions

func AddTagEventToImageStream 

func AddTagEventToImageStream(stream *ImageStream, tag string, next TagEvent) bool

AddTagEventToImageStream attempts to update the given image stream with a tag event. It will collapse duplicate entries - returning true if a change was made or false if no change occurred.

func ImageStreamToSelectableFields added in v1.0.8 

func ImageStreamToSelectableFields(ir *ImageStream) fields.Set

ImageStreamToSelectableFields returns a label set that represents the object.

func ImageToSelectableFields added in v1.0.8 

func ImageToSelectableFields(image *Image) fields.Set

func JoinImageStreamTag 

func JoinImageStreamTag(name, tag string) string

func NormalizeImageStreamTag added in v1.0.8 

func NormalizeImageStreamTag(name string) string

NormalizeImageStreamTag normalizes an image stream tag by defaulting to 'latest' if no tag has been specified.

func ShortDockerImageID added in v1.0.7 

func ShortDockerImageID(image *DockerImage, length int) string

ShortDockerImageID returns a short form of the provided DockerImage ID for display

func SortStatusTags added in v1.0.6 

func SortStatusTags(tags map[string]TagEventList) []string

func SplitImageStreamTag 

func SplitImageStreamTag(nameAndTag string) (name string, tag string, ok bool)

SplitImageStreamTag turns the name of an ImageStreamTag into Name and Tag. It returns false if the tag was not properly specified in the name.

func UpdateChangedTrackingTags added in v1.0.7 

func UpdateChangedTrackingTags(new, old *ImageStream) int

UpdateChangedTrackingTags identifies any tags in the status that have changed and ensures any referenced tracking tags are also updated. It returns the number of updates applied.

func UpdateTrackingTags 

func UpdateTrackingTags(stream *ImageStream, updatedTag string, updatedImage TagEvent) int

UpdateTrackingTags sets updatedImage as the most recent TagEvent for all tags in stream.spec.tags that have from.kind = "ImageStreamTag" and the tag in from.name = updatedTag. from.name may be either <tag> or <stream name>:<tag>. For now, only references to tags in the current stream are supported.

For example, if stream.spec.tags[latest].from.name = 2.0, whenever an image is pushed to this stream with the tag 2.0, status.tags[latest].items[0] will also be updated to point at the same image that was just pushed for 2.0.

Returns the number of tags changed.
