## What it is
A custom Kubernetes controller written in Go that synchronizes Secrets, ConfigMaps, Roles, RoleBindings, and ServiceAccounts across namespaces. It supports push-based and pull-based replication and is deployable via Helm or raw manifests.

## Use cases
- sync kubernetes secrets across namespaces
- replicate configmaps to multiple namespaces
- share tls certificates between namespaces
- keep rolebindings consistent cluster-wide
- deploy a secret replication controller via helm

## When to choose
- you need the same secret or configmap in many namespaces
- you want automatic propagation when a source resource changes
- you prefer a Helm-installable, cluster-scoped solution

## When to avoid
- you only have a single namespace
- you need cross-cluster replication rather than intra-cluster
- you cannot grant the controller RBAC permissions to manage secrets

## Facets
- artifact type: service
