Functions

func AddTagEventToImageStream added in v0.4.3 

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

func DifferentTagEvent added in v1.1.2 

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

DifferentTagEvent returns true if the supplied tag event matches the current stream tag event. Generation is not compared.

func HasTagCondition added in v1.1.2 

func HasTagCondition(stream *ImageStream, tag string, condition TagEventCondition) bool

HasTagCondition returns true if the specified image stream tag has a condition with the same type, status, and reason (does not check generation, date, or message).

func ImageStreamToSelectableFields added in v1.0.8 

func ImageStreamToSelectableFields(ir *ImageStream) fields.Set

ImageStreamToSelectableFields returns a label set that represents the object.

func PrioritizeTags(tags []string)

PrioritizeTags orders a set of image tags with a few conventions:

1. the "latest" tag, if present, should be first 2. any tags that represent a semantic major version ("5", "v5") should be next, in descending order 3. any tags that represent a semantic minor version ("5.1", "v5.1") should be next, in descending order 4. any tags that represent a full semantic version ("5.1.3-other", "v5.1.3-other") should be next, in descending order 5. any remaining tags should be sorted in lexicographic order

The method updates the tags in place.

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.

TagReference specifies optional annotations for images using this tag and an optional reference to an ImageStreamTag, ImageStreamImage, or DockerImage this tag should track.

func FollowTagReference added in v1.1.2 

func FollowTagReference(stream *ImageStream, tag string) (finalTag string, ref *TagReference, ok bool, multiple bool)

FollowTagReference walks through the defined tags on a stream, following any referential tags in the stream. Will return ok if the tag is valid, multiple if the tag had at least reference, and ref and finalTag will be the last tag seen. If a circular loop is found ok will be false.
