Variables ¶
var IsNewNwPolicyVerFlag = false
IsNewNwPolicyVerFlag indicates if the current kubernetes version is newer than 1.11 or not
Functions ¶
func CompareK8sVer ¶
CompareK8sVer compares two k8s versions. returns -1, 0, 1 if firstVer smaller, equals, bigger than secondVer respectively. returns -2 for error.
func DropEmptyFields ¶
DropEmptyFields deletes empty entries from a slice.
func GetClusterID ¶
GetClusterID retrieves cluster ID through node name. (Azure-specific)
func GetHashedName ¶
GetHashedName returns hashed ipset name.
func GetLabelsWithoutOperators ¶
GetLabelsWithoutOperators returns labels without operators.
func GetOperatorAndLabel ¶
GetOperatorAndLabel returns the operator associated with the label and the label without operator.
func IsNewNwPolicyVer ¶
IsNewNwPolicyVer checks if the current k8s version >= 1.11, if so, then the networkPolicy should support 'AND' between namespaceSelector & podSelector.
func SetIsNewNwPolicyVerFlag ¶
SetIsNewNwPolicyVerFlag sets IsNewNwPolicyVerFlag variable depending on version.
func SortMap ¶
SortMap sorts the map by key in alphabetical order. Note: even though the map is sorted, accessing it through range will still result in random order.
func UniqueStrSlice ¶
UniqueStrSlice removes duplicate elements from the input string.
