httpbin 基于 Gin 开发,用于快速测试基于云原生微服务可观测性和流量管理等功能。
服务可观测性包括:
- 日志
- 指标
- 调用链路跟踪
流量管理包括:
- 网关
- Envoy & Istio
- 服务发现

- 支持 SkyWalking、Zipkin 调用链路跟踪
- 支持 HTTP 接口 /metrics 指标输出
- Readiness、Liveness、Startup 探针
- 通过 /service?services=middle,backend 来模拟调用链路
- 支持日志集成 Trace
- 接入 OpenTelemetry & Jaeger
- Grafana metric 看板
- 基于 Isito 流量管理样例
- 其他 httpbin 原始接口迁移
- 接入 Nacos 服务发现
docker pull cr7258/httpbin:v1
- 部署 deployment
kubectl apply -f deploy/basic.yaml
- 本地端口转发
kubectl -n app-system port-forward service/basic 9090:80
- 测试接口 /hostname 接口 输出 POD_NAME
curl -v http://127.0.0.1:9090/hostname
"basic-6d6969cf9c-llzcp"
- 测试 / 接口 输出整个请求头,请求参数,请求体,环境变量,调用链路等信息
