The etcd Operator is a Kubernetes-native tool designed to simplify the deployment, management, and operation of etcd clusters within a Kubernetes environment. It leverages Kubernetes Custom Resource Definitions (CRDs) to define and manage etcd clusters, including their configuration, scaling, backups, and restores.

• **Kubernetes Custom Resources:** Employs familiar Kubernetes manifests to configure and deploy etcd clusters.
• **Simplified Deployment Configuration:** Essential etcd configurations like versions, node types, storage, and security settings are defined directly within Kubernetes resources.
• **Automated Cluster Management:** Facilitates the creation, scaling, upgrading, and management of etcd clusters, including automated failover and recovery.
• **High Availability:** Ensures high availability by managing multiple etcd nodes within a cluster.
• **Backup and Restore:** Supports automated and on-demand backups and restores of etcd data.
• **Security:** Enforces security measures such as TLS encryption, authentication, and authorization to protect data.
• **Monitoring and Metrics:** Integrates with Prometheus for monitoring and metrics collection to track the health and performance of etcd clusters.

• **Streamlined etcd Deployment:** Simplifies the process of setting up and managing etcd in Kubernetes.
• **Scalability:** Effortlessly scales etcd clusters to accommodate growing data needs.
• **High Availability:** Configures etcd clusters for high availability, ensuring data durability and accessibility.
• **Open Source:** The etcd Operator is an open-source project under the Apache 2.0 License.

• **Installation:** Install the etcd Operator using Helm or by directly applying the necessary manifests to your Kubernetes cluster.
• **Configuration:** Define etcd clusters and related resources using Kubernetes Custom Resource Definitions (CRDs).
• **Management:** The etcd Operator will automatically deploy and manage your etcd clusters based on your configurations.
