+一、安装 cert-manager
+OpenTelemetry Operator 提供了 OpenTelemetryCollector CRD（自定义资源定义），能自动处理服务发现和 RBAC（基于角色的访问控制）
+该 Operator 需要 cert-manager 来支持准入 Webhook，部署步骤如下：
+
+安装OpenTelemetry Operator 自定义资源，需先部署 cert-manager ，使用yaml 直接部署，文件：02-cert-manager.yaml (官方文档里)
+官方文档链接：https://cert-manager.io/docs/installation/kubectl/
+
+cert-manager 将安装在cert-manager命名空间中，安装了cert-manager后，通过以下方式验证其部署是否正确 检查cert-manager命名空间: 
+kubectl get pods --namespace cert-manager
+NAME                                       READY   STATUS    RESTARTS   AGE
+cert-manager-7b8b89f89d-tpchr              1/1     Running   0          24s
+cert-manager-cainjector-7f9fdd5dd5-px66h   1/1     Running   0          25s
+cert-manager-webhook-769f6b94cb-zmjmv      1/1     Running   0          24s
+
+
+
+二、安装 OpenTelemetry Operator
+使用 helm 安装OpenTelemetry ，添加 Operator helm 仓库、更新、安装：
+helm repo add open-telemetry https://open-telemetry.github.io/opentelemetry-helm-charts
+helm repo update
+helm install opentelemetry-operator open-telemetry/opentelemetry-operator \
+  --namespace opentelemetry-operator \
+  --create-namespace
+
+或者直接使用yaml部署：文件 03-opentelemetry-operator.yaml
+kubectl apply -f https://github.com/open-telemetry/opentelemetry-operator/releases/latest/download/opentelemetry-operator.yaml
+
+kubectl delete -f https://github.com/open-telemetry/opentelemetry-operator/releases/latest/download/opentelemetry-operator.yaml
+
+# 查看安装的CRD
+kubectl get crd | grep opentelemetry.io
