## Kubernetes Annotations
Kubernetes annotations are designed to solve exactly this problem. Oft-overlooked, Kubernetes annotations are designed to add metadata to Kubernetes objects. The Kubernetes documentation says annotations can “attach arbitrary non-identifying metadata to objects.” This means that annotations should be used for attaching metadata that is external to Kubernetes (i.e., metadata that Kubernetes won’t use to identify objects. As such, annotations can contain any type of data. This is a contrast to labels, which are designed for uses internal to Kubernetes. As such, label structure and values are [constrained](https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#syntax-and-character-set) so they can be efficiently used by Kubernetes.
