accurate-controller

accurate-controller is a Kubernetes controller to manage sub-namespaces and to propagate resources from parents to their children namespaces.

Configuration file

accurate-controller reads a configuration file on startup. The default location is /etc/accurate/config.yaml. The location can be changed with --config-file flag.

The configuration file should be a JSON or YAML file having the following keys:

Key	Type	Description
`labelKeys`	`[]string`	Keys of namespace labels to be propagated.
`annotationKeys`	`[]string`	Keys of namespace annotations to be propagated.
`subNamespaceLabelKeys`	`[]string`	Keys of SubNamespace labels to be propagated.
`subNamespaceAnnotationKeys`	`[]string`	Keys of SubNamespace annotations to be propagated.
`watches`	`[]object`	GroupVersionKind of namespace-scoped objects to be propagated.

Example:

labelKeys:
- team

annotationKeys:
- foo.bar/baz

subNamespaceLabelKeys:
- app

subNamespaceAnnotationKeys:
- foo.bar/baz

watches:
- group: rbac.authorization.k8s.io
  version: v1
  kind: Role
- group: rbac.authorization.k8s.io
  version: v1
  kind: RoleBinding
- version: v1
  kind: Secret

Environment variables

Name	Required	Description
`POD_NAMESPACE`	Yes	The namespace name where `accurate-controller` is running.
