Namespace types

Accurate defines the following types of Namespaces:

• Template: Namespace labeled with accurate.cybozu.com/type=template
• Root: Namespace labeled with accurate.cybozu.com/type=root
• Sub-namespace: Namespace labeled with accurate.cybozu.com/parent=<name>

Any Namespace other than sub-namespaces can reference a template Namespace with accurate.cybozu.com/template=<name> label.

Sub-namespace can reference a root or another sub-namespace as its parent.

When configured to do so, Accurate propagates the Namespace labels, annotations, and namespace-scope resources from a referenced Namespace to referencing Namespaces.

Circular references are prohibited by an admission webhook.

Resource propagation

Accurate propagates any namespace-scope resource that are annotated with accurate.cybozu.com/propagate=<mode>.

Mode is one of the following:

• create: the resource will be created in referencing Namespaces if missing.
• update: the resource will be created in referencing Namespaces if missing, or will be updated if not identical, or will be deleted when the resource in the referenced Namespace is deleted.
