+# 基于 Pod 和 Service 注解的服务发现
+
+## 背景
+
+很多应用会为 Pod 或 Service 打上一些注解用于 Prometheus 的服务发现，如 `prometheus.io/scrape: "true"`，这种注解并不是 Prometheus 官方支持的，而是社区的习惯性用法，要使这种注解生效，还需结合 Prometheus 的采集配置，本文介绍具体的配置方法。
+
+## 真实案例
+
+### istio 指标采集
+
+[istio](https://istio.io/) 使用了这种 Pod 注解，当 Pod 被自动注入 sidecar 的同时也会被自动注入以下注解：
+
+```yaml
+    prometheus.io/path: /stats/prometheus
+    prometheus.io/port: "15020"
+    prometheus.io/scrape: "true"
+```
+
+表示声明让 Prometheus 采集 Envoy Sidecar 暴露的 metrics，端口是 15020，路径是 `/stats/prometheus`。
+
+除此之外，控制面组件 istiod 的 Pod 也会有类似注解：
+
+```yaml
+    prometheus.io/port: "15014"
+    prometheus.io/scrape: "true"
+```
+
+### Kubernetes Addon 指标采集
+
+Kubenretes 源码仓库中的一些 addon 组件也使用了这种注解，有的是 Pod 注解，有的是 Service 注解。
+* [coredns](https://github.com/kubernetes/kubernetes/blob/release-1.30/cluster/addons/dns/coredns/coredns.yaml.base#L196-L197) 使用 Service 注解：
+  ```yaml showLineNumbers
+  apiVersion: v1
+  kind: Service
+  metadata:
+    name: kube-dns
+    namespace: kube-system
+    annotations:
+      # highlight-start
+      prometheus.io/port: "9153"
+      prometheus.io/scrape: "true"  
+      # highlight-end
+  ```
+* [nodelocaldns](https://github.com/kubernetes/kubernetes/blob/release-1.30/cluster/addons/dns/nodelocaldns/nodelocaldns.yaml#L125-L126) 使用 Pod 注解：
+  ```yaml showLineNumbers
+  apiVersion: apps/v1
+  kind: DaemonSet
+  metadata:
+    name: node-local-dns
+    namespace: kube-system
+    labels:
+      k8s-app: node-local-dns
+      kubernetes.io/cluster-service: "true"
+      addonmanager.kubernetes.io/mode: Reconcile
+  spec:
+    updateStrategy:
+      rollingUpdate:
+        maxUnavailable: 10%
+    selector:
+      matchLabels:
+        k8s-app: node-local-dns
+    template:
+      metadata:
+        labels:
+          k8s-app: node-local-dns
+        annotations:
+          # highlight-start
+          prometheus.io/port: "9253"
+          prometheus.io/scrape: "true"
+          # highlight-end
+  ```
