发布日期: 2026-03-20
版本号: v3.5.28

该文本是etcd v3.5.28版本的安装与入门指南。首先，它提示用户在升级前务必查阅详细的变更日志和升级指南，因为可能存在破坏性更改。对于安装，指南推荐通过play.etcd.io网站或官方操作文档进行学习，并提供了支持的平台列表。具体安装方法包括：对于Linux系统，通过指定的下载地址获取安装包，解压后即可使用etcd、etcdctl和etcdutl命令；对于macOS系统，流程类似，但使用.zip格式的压缩包；对于Docker环境，则主要从指定的容器镜像仓库拉取镜像来快速启动一个单节点的etcd服务。指南在每个平台部分都包含了验证安装（检查版本）和启动服务的基本命令示例。

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

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