config-reflector

config-reflector is a Kubernetes operator for sharing ConfigMap and Secret objects across namespaces.

Features

• Update event propagation to reflected objects
• Automatic garbage collection

Usage

1. Create a new namespace called config-reflector

   kubectl create ns config-reflector
   

2. Deploy manifests in ./deploy directory

   kubectl apply -f ./deploy
   

3. Check if operator pod is running in config-reflector namespace

   kubectl get pods -n config-reflector
   

4. Use following annotations to control how ConfigMaps and Secrets are reflected in other namespaces

   • configreflector.github.io/reflect-namespaces: default, test
     This annotation is used to pass operator a comma separated list of namespaces where annotated Object should be reflected.
   • configreflector.github.io/reflect-annotations: "true"
     This annotation tells operator whether it should copy annotations from source object to its reflection. By default, it is disabled. When enabled, operator related annotations are not copied.
   • configreflector.github.io/reflect-labels: "true"
     This annotation tells operator whether it should copy labels from source object to its reflection. It is disabled by default.
