Functions

func MakeEtcdItemKey

func MakeEtcdItemKey(ctx api.Context, prefix string, id string) (string, error)

MakeEtcdItemKey constructs etcd paths to a resource relative to prefix enforcing namespace rules. If no namespace is on context, it errors.

func MakeEtcdListKey

func MakeEtcdListKey(ctx api.Context, prefix string) string

MakeEtcdListKey constructs etcd paths to resource directories enforcing namespace rules
