## What it is
A Kubernetes operator that creates, configures, and manages etcd clusters on Kubernetes, automating cluster lifecycle tasks. It handles creation, resizing, failover, rolling upgrades, and backup/restore of etcd clusters via custom resources.

## Use cases
- run etcd clusters on kubernetes
- automate etcd cluster failover
- resize an etcd cluster declaratively
- rolling upgrade etcd versions on k8s
- backup and restore etcd clusters
- deploy etcd with a kubectl yaml manifest

## When to choose
- you need to operate etcd clusters on Kubernetes 1.8+ with etcd 3.2.x
- you want declarative, automated etcd lifecycle management including failover and backups

## When to avoid
- you need actively maintained software - the project is archived and no longer developed
- you run modern Kubernetes versions or newer etcd releases
- you need an operator for databases other than etcd

## Facets
- artifact type: service
- maturity: abandoned
- function: container-orchestration, database, deployment, backup
- domain: databases, self-hosted
- platform: go, self-hosted
- tags: etcd, kubernetes-operator, cluster-management, archived, failover, rolling-upgrade, containers, devops, kubernetes, docker
