Variables

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

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

Functions

func DefaultVariableResolver

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

DefaultVariableResolver is used in all variable substitutions except preconditions

func Evaluate

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

Evaluate evaluates the condition

func EvaluateConditions

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

EvaluateConditions evalues 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 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 RuleToUntyped

func RuleToUntyped(rule kyverno.Rule) (interface{}, error)

func SubstituteAll

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

func SubstituteAllForceMutate

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

func ValidateBackgroundModeVars(log logr.Logger, ctx context.EvalInterface, rule interface{}) (interface{}, error)

ValidateBackgroundModeVars validates variables against the specified context, which contains a list of allowed JMESPath queries in background processing, and throws an error if the variable is not allowed.

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
