# 健康检查
|
||||
|
||||
查询存活、数据库/迁移就绪状态与运行版本。
|
||||
|
||||
## 准备
|
||||
|
||||
- Go 1.27.1、当前版本 Orbit;服务启动和初始化见[仓库 README](../../README.md#快速开始)。
|
||||
- 无需凭据;服务地址必须可达。
|
||||
- [示例总索引](../README.md)提供统一初始化和权限说明;完整字段、失败处理见[详细手册](../../docs/api/health.md)。
|
||||
|
||||
## 运行
|
||||
|
||||
以下命令从仓库根目录执行;凭据路径替换为实际初始化输出。
|
||||
|
||||
```sh
|
||||
cd examples
|
||||
export ORBIT_URL=http://127.0.0.1:8080
|
||||
go run ./health
|
||||
```
|
||||
|
||||
## 结果核对
|
||||
|
||||
liveness=alive readiness=ready scope=database_and_schema。具体 ID 和统计值以本次运行为准。程序会核对上述关键条件,失败时打印错误并以非零状态退出。
|
||||
|
||||
## 接入自己的项目
|
||||
|
||||
阅读[main.go](main.go)中的客户端创建、请求及错误处理。业务项目通过 `go get git.yuntuo.hk/k2safe/orbit/sdk/go@v0.1.1` 引入 SDK,无需导入本示例包。
|
||||
|
||||
本例只读,不创建任务、队列或订阅。
