Functions

func ConvertClientObjectToMap

func ConvertClientObjectToMap(obj client.Object) (map[string]interface{}, error)

func EvaluateCheckHook

func EvaluateCheckHook(k8sClient client.Reader, hook *kubeobjects.HookSpec, log logr.Logger) (bool, error)

func EvaluateCheckHookExp

func EvaluateCheckHookExp(booleanExpression string, jsonData interface{}) (bool, error)

func EvaluateCheckHookForObjects

func EvaluateCheckHookForObjects(objs []client.Object, hook *kubeobjects.HookSpec, log logr.Logger) (bool, error)

func IsValidJSONPathExpression

Types

type CheckHook

type CheckHook struct {
	Hook *kubeobjects.HookSpec
}

func (CheckHook) Execute

func (c CheckHook) Execute(client client.Client, log logr.Logger) error

type ExecHook

type ExecHook struct {
	Hook *kubeobjects.HookSpec
}

func (ExecHook) Execute

func (e ExecHook) Execute(client client.Client, log logr.Logger) error

type HookExecutor

type HookExecutor interface {
	Execute(client client.Client, log logr.Logger) error
}

Hook interface will help in executing the hooks based on the types. Supported types are "check", "scale" and "exec". The implementor needs return the result which would be boolean and error if any.

func GetHookExecutor

func GetHookExecutor(hook kubeobjects.HookSpec) (HookExecutor, error)

Based on the hook type, return the appropriate implementation of the hook.
