Elastic APM Opentracing 遇到 Docker apm-server 的 CORS 问题

Question

给定这个 docker 文件来设置后端服务，包括：elasticsearch、apm-server、kibana、jaeger-collector、jaeger-agent、jaeger-query、grafana。

apm-server:
image: docker.elastic.co/apm/apm-server:6.8.1
ports:
  - 8200:8200
environment:
  - output.elasticsearch.hosts=['http://elasticsearch:9200']
  - apm-server.host="0.0.0.0:8200"
  - apm-server.rum.enabled=true
  - setup.kibana.host="kibana:5601"
  - setup.template.enabled=true
  - logging.to_files=false
networks:
  - elastic-jaeger

我正在从我的 Angular 客户端运行带有 Opentracing 的 Elastic APM：

const elasticApm = initApm({
  serviceName: `Test`,
  serviceUrl: `127.0.0.1:8200`,
  // serviceVersion: ``,
  active: true,
  environment: ``, // production, development, test, etc
  logLevel: `warn`, // Possible levels are: trace, debug, info, warn, error
  flushInterval: 500, // ms
  errorThrottleLimit: 20, // errors
  errorThrottleInterval: 30000, // ms
  transactionSampleRate: 1.0,
  distributedTracing: true,
  distributedTracingOrigins: ['http://foo.com']
});

const elasticTracer = createTracer(elasticApm);
this.opentracing.initGlobalTracer(elasticTracer);

我遇到了 CORS 问题：

我的目标是将 Angular 和弹性 APM 的 opentracing 客户端连接到 docker 内的服务。

还有一些额外的问题和文档涵盖了 apm-server 的 CORS：

Distributed Tracing Guide

Config with RUM enabled

看起来配置应该可以工作，因为Default value is set to ['*'], which allows everything.

尝试使用配置：

文件 apm-server/config/apm-server.yml 包含您的配置内容：

apm-server.rum.enabled: true
apm-server.rum.event_rate.limit: 300
apm-server.rum.event_rate.lru_size: 1000
apm-server.rum.allow_origins: ['*']
apm-server.rum.library_pattern: "node_modules|bower_components|~"

apm-server.rum.source_mapping.index_pattern: "apm-*-sourcemap*"
output.elasticsearch.hosts: ["http://elasticsearch:9200"]
apm-server.host: "0.0.0.0:8200"
setup.kibana.host: "kibana:5601"
setup.template.enabled: true
logging.to_files: false

注意 rum.allow_origins 选项，您可以配置该选项来解决 CORS 问题。 https://www.elastic.co/guide/en/apm/agent/rum-js/master/configuring-cors.html
