Introduction External Secrets Operator (ESO) is a Kubernetes operator that allows you to use external secret management systems, such as AWS Secrets Manager, HashiCorp Vault, and Azure Key Vault, to manage secrets in your Kubernetes cluster. It provides a way to synchronize secrets from these external systems into Kubernetes secrets, making it easier to manage and use secrets in your applications. In this guide, we will demonstrate how to use the External Secrets Operator to synchronize secrets from one Kubernetes cluster (Cluster 1(Upstream Cluster)) to another (Cluster 2,(Downstream Cluster/s)). This is particularly useful when you want to share secrets between different clusters or environments. ...
