The etcd-operator project has been donated to Cozystack and relaunched with a new v1alpha2 API (etcd-operator.cozystack.io/v1alpha2). The rewrite, authored by Timofei Larkin, abandons StatefulSet-based member management in favor of directly driving etcd's native Membership API (MemberAdd, MemberPromote, MemberRemove). Each cluster member gets its own EtcdMember resource with an independently reconciled Pod and PVC. Key new capabilities include scale-to-zero (pause/resume), tmpfs-backed storage, CEL-based CRD validation without webhooks, automatic PodDisruptionBudget, snapshot/restore via EtcdSnapshot, TLS with cert-manager integration, and a kubectl-etcd plugin for day-2 operations. An in-place migration tool (etcd-migrate) allows upgrading from v1alpha1 without data movement or quorum loss. The post also compares feature coverage against the official etcd-io/etcd-operator roadmap, where v1alpha2 leads on most items.
