发布日期: 2026-06-01
版本号: v3.4.45

请查看 etcd 3.4 版本的变更日志以获取完整更新列表，并在升级前阅读升级指南，因为可能存在破坏性变更。安装指南可参考 etcd 操作文档，支持平台信息见支持平台页面。

Linux 系统可从 Google 或 GitHub 下载 etcd v3.4.45，解压后使用 etcd、etcdctl 和 etcdutl 等工具，并可通过本地命令启动服务及进行读写测试。

macOS 系统类似，下载对应版本的压缩包，解压并验证工具版本。

Docker 用户可使用官方镜像启动容器，映射端口和数据目录，配置集群参数后通过 exec 命令进行版本检查和功能测试。

etcd 主要使用 gcr.io/etcd-development/etcd 作为容器镜像仓库，次要使用 quay.io/coreos/etcd。

etcd uses gcr.io/etcd-development/etcd as a primary container registry, and quay.io/coreos/etcd as secondary.
