在k8s中打开遥测python自动仪表不收集数据

Question

因此，我正在尝试使用开放遥测技术来测试FastAPI python服务器。我通过诗歌安装了所需的依赖项：

opentelemetry-api = "^1.11.1"
opentelemetry-distro = {extras = ["otlp"], version = "^0.31b0"}
opentelemetry-instrumentation-fastapi = "^0.31b0"

在本地运行服务器时，在使用opentelemetry-instrument --traces_exporter console uvicorn src.main:app --host 0.0.0.0 --port 5000时，每当调用任何端点时，我都可以看到输出到控制台的跟踪。

我面临的主要问题是，当在k8s中运行应用程序时，在收集器中看不到日志。

我添加了cert管理器kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.8.0/cert-manager.yaml ( OTel操作符需要)和OTel运算符本身install the operator kubectl apply -f https://github.com/open-telemetry/opentelemetry-operator/releases/latest/download/opentelemetry-operator.yaml。

然后，我使用以下配置添加了一个收集器：

apiVersion: opentelemetry.io/v1alpha1
kind: OpenTelemetryCollector
metadata:
  name: otel
spec:
  config: |
    receivers:
      otlp:
        protocols:
          grpc:
          http:
    processors:

    exporters:
      logging:

    service:
      pipelines:
        traces:
          receivers: [otlp]
          processors: []
          exporters: [logging]

最后，为启用自动检测设备，提供了一种仪器CR：

apiVersion: opentelemetry.io/v1alpha1
kind: Instrumentation
metadata:
  name: my-instrumentation
spec:
  exporter:
    endpoint: http://otel-collector:4317
  propagators:
    - tracecontext
    - baggage
  sampler:
    type: parentbased_traceidratio
    argument: "0.25"

我的应用程序的部署包括：

apiVersion: apps/v1
kind: Deployment
metadata:
  annotations:
    kompose.cmd: kompose convert -f docker-compose-run-local-with-aws.yml -c
    kompose.version: 1.26.1 (HEAD)
  creationTimestamp: null

            - name: RELEASE_VERSION
              value: "1.0.0"
            - name: OTEL_RESOURCE_ATTRIBUTES
              value: "service.name=fastapiApp"
            - name: OTEL_LOG_LEVEL
              value: "debug"
            - name: OTEL_TRACES_EXPORTER
              value: otlp_proto_http
            - name: OTEL_EXPORTER_OTLP_ENDPOINT
              value: http://otel-collector:4317
          image: my_org/api:1.0.0
          name: api
          ports:
            - containerPort: 5000
          resources: {}
          imagePullPolicy: IfNotPresent
      restartPolicy: Always

我遗漏了什么？我每件事都检查了一千遍，不知道可能出了什么问题。

您已经错误地配置了导出端点设置OTEL_EXPORTER_OTLP_ENDPOINT。OTLP over HTTP导出程序的端点值应该有端口号4318。第4317号港口号应用于OTLP/gRPC出口商。
