opentelemetry-collector docker安装

一、编写配置

nano /root/otelcol-config.yaml
==================================================
receivers:
  otlp:
    protocols:
      grpc:
        endpoint: 0.0.0.0:4317
      http:
        endpoint: 0.0.0.0:4318
exporters:
  debug:
    verbosity: detailed
service:
  pipelines:
    traces:
      receivers: [otlp]
      exporters: [debug]
    metrics:
      receivers: [otlp]
      exporters: [debug]
    logs:
      receivers: [otlp]
      exporters: [debug]
==================================================

启动

docker run -d --name opentelemetry-collector -v /root/otelcol-config.yaml:/etc/otelcol-contrib/config.yaml -p 1888:1888 -p 8888:8888 -p 8889:8889 -p 13133:13133 -p 4317:4317 -p 4318:4318 -p 55679:55679 otel/opentelemetry-collector-contrib:0.117.0
