import ( "fmt" "k8s.io/kubernetes/pkg/util" ) func main() { mySet := util.StringSet{} mySet.Insert("apple", "banana", "orange") fmt.Println("Initial Set:", mySet.List()) mySet.Insert("pear") fmt.Println("Updated Set:", mySet.List()) mySet.Delete("banana") fmt.Println("Updated Set:", mySet.List()) fmt.Println("Set Contains Apple?", mySet.Has("apple")) }In this example, we create a new StringSet, insert some values, update the set to include a new value, delete a value, and check if a value exists in the set. The List() method returns the current set as a list of strings. The StringSet List data structure is part of the Kubernetes API package, which provides utility functions and data structures for working with Kubernetes objects.
