Variables

var RegexEscpReferences = regexp.MustCompile(`\\\$\(.[^\ ]*\)`)

RegexEscpReferences is the Regex for '\$(...)'

var RegexEscpVariables = regexp.MustCompile(`\\\{\{(\{[^{}]*\}|[^{}])*\}\}`)

var RegexReferences = regexp.MustCompile(`^\$\(.[^\ ]*\)|[^\\]\$\(.[^\ ]*\)`)

RegexReferences is the Regex for '$(...)' at the beginning of the string, and 'x$(...)' where 'x' is not '\'

var RegexVariables = regexp.MustCompile(`^\{\{(\{[^{}]*\}|[^{}])*\}\}|[^\\]\{\{(\{[^{}]*\}|[^{}])*\}\}`)

Functions

func ConditionsToJSONObject

func ConditionsToJSONObject(conditions []*kyverno.AnyAllConditions) ([]map[string]interface{}, error)

func DefaultVariableResolver

func DefaultVariableResolver(ctx context.EvalInterface, variable string) (interface{}, error)

DefaultVariableResolver is used in all variable substitutions except preconditions

func DocumentToUntyped

func DocumentToUntyped(doc interface{}) (interface{}, error)

func Evaluate

func Evaluate(log logr.Logger, ctx context.EvalInterface, condition kyverno.Condition) bool

Evaluate evaluates the condition

func EvaluateAnyAllConditions

func EvaluateAnyAllConditions(log logr.Logger, ctx context.EvalInterface, conditions []*kyverno.AnyAllConditions) bool

func EvaluateConditions

func EvaluateConditions(log logr.Logger, ctx context.EvalInterface, conditions interface{}) bool

EvaluateConditions evaluates all the conditions present in a slice, in a backwards compatible way

func FindAndShiftReferences

func FindAndShiftReferences(log logr.Logger, value, shift, pivot string) string

func IsReference

func IsReference(value string) bool

IsReference returns true if the element contains a 'valid' reference $()

func IsVariable

func IsVariable(value string) bool

IsVariable returns true if the element contains a 'valid' variable {{}}

func JSONObjectToConditions

func JSONObjectToConditions(data interface{}) ([]*kyverno.AnyAllConditions, error)

func ReplaceAllVars

func ReplaceAllVars(src string, repl func(string) string) string

ReplaceAllVars replaces all variables with the value defined in the replacement function This is used to avoid validation errors

func SubstituteAll

func SubstituteAll(log logr.Logger, ctx context.EvalInterface, document interface{}) (_ interface{}, err error)

SubstituteAll substitutes variables and references in the document. The document must be JSON data i.e. string, []interface{}, map[string]interface{}

func SubstituteAllForceMutate

func SubstituteAllForceMutate(log logr.Logger, ctx *context.Context, typedRule kyverno.Rule) (_ kyverno.Rule, err error)

func SubstituteAllInConditions

func SubstituteAllInConditions(log logr.Logger, ctx context.EvalInterface, conditions []*kyverno.AnyAllConditions) ([]*kyverno.AnyAllConditions, error)

func SubstituteAllInPreconditions

func SubstituteAllInPreconditions(log logr.Logger, ctx context.EvalInterface, document interface{}) (_ interface{}, err error)

func SubstituteAllInRule

func SubstituteAllInRule(log logr.Logger, ctx context.EvalInterface, typedRule kyverno.Rule) (_ kyverno.Rule, err error)

func UntypedToRule

func UntypedToRule(untyped interface{}) (kyverno.Rule, error)

func ValidateElementInForEach

func ValidateElementInForEach(log logr.Logger, rule interface{}) (interface{}, error)

Types

type NotResolvedReferenceErr

type NotResolvedReferenceErr struct {
	// contains filtered or unexported fields
}

NotResolvedReferenceErr is returned when it is impossible to resolve the variable

func (NotResolvedReferenceErr) Error

func (n NotResolvedReferenceErr) Error() string

type VariableResolver

type VariableResolver = func(ctx context.EvalInterface, variable string) (interface{}, error)

VariableResolver defines the handler function for variable substitution
