发布日期: 2023-04-14
版本号: v3.4.25

请查看变更日志以获取完整更改列表，并在升级etcd前阅读升级指南（可能存在破坏性变更）。安装指南可参考官方文档，了解支持的平台信息。

Linux/macOS安装步骤：

  1. 下载etcd v3.4.25版本压缩包（支持Google或GitHub源）
  2. 解压文件至临时目录，验证etcd及etcdctl版本
  3. 启动本地etcd服务，通过etcdctl进行键值读写操作

Docker部署方式：

  • 使用gcr.io或quay.io的镜像
  • 运行容器时绑定数据目录并配置端口、集群参数
  • 通过docker exec执行版本检查、健康状态查询及数据读写

所有系统均需注意操作前清理临时文件，测试完成后可通过示例命令验证基础功能。

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