Pointers to logging, monitoring, analytics, or audit repositories. annotations - (Optional) An unstructured key value map stored with the namespace that may be used to store arbitrary metadata.Build, release, or image information like timestamps, release IDs, git branch, PR numbers, image hashes, and registry address.This would be a solid use case for labels, allowing you to indicate which of these release types a given object falls under. By default, the component chart sets a couple of annotations following the best practices. Annotating pods or deployments will take precedence on the namespace annotation. For example, your team might have different release types, such as alpha, beta, and stable. Here are some examples of information that could be recorded in annotations: The annotations option expects a map with Kubernetes annotations. The metadata in an annotation can be small or large, structured or unstructured, and can include characters not permitted by labels.Īnnotations, like labels, are key/value maps: Image one here illustrates the demonstrated solution, where example service, nginx-hello, deployed to Kubernetes cluster, cls1, is both discoverable and consumable from Kubernetes cluster cls2, using the MCS-Controller. My understanding of annotations is that it is metadata that adds key-value pairs that cannot be used by Kubernetes for identifying/filtering the resource. In contrast, annotations are not used to identify and select objects. 18 Im trying to wrap my head around the difference between annotations and labels. Clients such as tools and libraries can retrieve this metadata. Kubernetes annotations is used to attach arbitrary non-identifying metadata to objects. There are two way using you can attach metadata to Kubernetes objects.
