etcd v3.4.42 版本更新介绍

发布日期: 2026-03-20
版本号: v3.4.42

请查阅变更日志了解完整变更列表，并在升级etcd前务必阅读升级指南（可能存在破坏性更改）。安装指南可参考play.etcd.io和etcd操作文档，最新支持的平台信息请查看支持平台页面。
Linux系统安装版本v3.4.42时，可通过Google或GitHub下载链接获取tar.gz压缩包，解压后使用etcd、etcdctl和etcdutl命令验证版本并启动本地服务器。
macOS系统安装同版本时，下载zip压缩包并解压，同样验证版本信息。
Docker部署使用官方镜像（gcr.io/etcd-development/etcd或quay.io/coreos/etcd），通过指定参数运行容器并挂载数据目录，支持通过docker exec执行版本检查、健康检查及读写操作。

Docker

etcd主要使用gcr.io/etcd-development/etcd作为容器注册表，quay.io/coreos/etcd为备用。

Docker

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