在下文中一共展示了Labels类的3个代码示例，这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞，您的评价将有助于系统推荐出更棒的Golang代码示例。
示例1: fetchImage
func (h *Host) fetchImage(name types.ACIdentifier, labels types.Labels) (*Image, error) {
if aci, asc, err := fetch.DiscoverACI(discovery.App{Name: name, Labels: labels.ToMap()}); err != nil {
return nil, errors.Trace(err)
} else if aci == nil {
return nil, ErrNotFound
} else {
return h.ImportImage(name, aci, asc)
}
}示例2: MatchLabels
// True if all labels in `labels` are present in `candidate` and have
// the same value
func MatchLabels(labels, candidate types.Labels) bool {
if len(labels) == 0 {
return true
}
cmap := candidate.ToMap()
for _, label := range labels {
if v, ok := cmap[label.Name]; !ok || v != label.Value {
return false
}
}
return true
}示例3: GetACI
// GetACI retrieves the ACI that best matches the provided app name and labels.
// The returned value is the blob store key of the retrieved ACI.
// If there are multiple matching ACIs choose the latest one (defined as the
// last one imported in the store).
// If no version label is requested, ACIs marked as latest in the ACIInfo are
// preferred.
