+# replicator
+
+Kubernetes Replicator (mittwald/kubernetes‑replicator) is a lightweight controller that automatically copies Secrets and ConfigMaps between namespaces. It is ideal for sharing resources like wildcard TLS certificates generated by cert‑manager across multiple namespaces without manual copying.
+
+Replicator watches for annotations on a source Secret and keeps synchronized copies updated in the target namespaces. It preserves custom metadata and removes cert‑manager‑specific annotations from the replicated secrets to avoid conflicts. When cert‑manager renews a certificate, Replicator automatically updates all replicated copies.
+
+``` bash
+helm repo add mittwald https://helm.mittwald.de
+kubectl create namespace replicator
+helm repo update
+helm upgrade --install replicator mittwald/kubernetes-replicator \
+  --namespace replicator
+```
