如何使用 elasticsearch 配置 Jaeger？

Question

我曾嘗試執行此 docker 命令以使用 elasticsearch 設置 Jaeger Agent 和 jaeger 收集器。

sudo docker run \
-p 5775:5775/udp \
-p 6831:6831/udp \
-p 6832:6832/udp \
-p 5778:5778 \
-p 16686:16686 \
-p 14268:14268 \
-e SPAN_STORAGE_TYPE=elasticsearch \
--name=jaeger \
jaegertracing/all-in-one:latest 

但是這個命令給出了以下錯誤。 如何使用 ElasticSearch 配置 Jaeger？

"msg":"Failed to init storage factory","error":"health check timeout: no Elasticsearch node available","errorVerbose":"no Elasticsearch node available\

Answer 1

在搜索了一段時間的解決方案后，我找到了一個 docker-compose.yml 文件，其中包含 Jaeger Query、Agent、collector 和 Elasticsearch 配置。

docker-compose.yml

docker-compose.yml 文件安裝elasticsearch、Jaeger 收集器、查詢和代理。

先安裝docker和docker compose https://docs.docker.com/compose/install/#install-compose

然后依次執行這些命令

 
1. sudo docker-compose up -d elasticsearch

2. sudo docker-compose up -d 

3. sudo docker ps -a

啟動所有 docker 容器 - Jaeger 代理、收集器、查詢和彈性搜索。

如果您想使用 Elasticsearch 和 Kibana 部署 Jaeger 以快速驗證和檢查堆棧，例如 in kind 或 Minikube，以下代碼段可能對您有所幫助。

Answer 3

正如我在上面對 OP 的第一個答案的評論中提到的那樣，完全按照給定的方式運行 docker-compose 時出現錯誤：

Error: unknown flag: --collector.host-port

我認為自從編寫該答案以來，Jaeger 人員已棄用此 CLI 標志。 所以我在 jaeger-agent 文檔中翻了一下：

1. https://www.jaegertracing.io/docs/1.20/deployment/#discovery-system-integration
2. https://www.jaegertracing.io/docs/1.20/cli/#jaeger-agent

我通過一些小的修改讓它工作：

1. 我將端口范圍"14250:14250"到 jaeger-collector 端口
2. 我更新了 jaeger-agent 命令輸入： command: ["--reporter.grpc.host-port=jaeger-collector:14250"]
3. 最后，我將image標簽中的彈性搜索版本更新為他們目前可用的最新版本（盡管我懷疑這是必需的）。

更新后的 docker-compose.yaml：

version: "3"

services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.9.3
    networks:
      - elastic-jaeger
    ports:

Answer 4

如果需要在 Kubernetes 集群中設置 Jaeger 作為 helm chart，可以使用這個： https : //github.com/jaegertracing/helm-charts/tree/master/charts/jaeger它可以將 Elasticsearch 或 Cassandara 部署為存儲后端。 這只是傳遞給圖表的正確值的問題：

storage:
  type: elasticsearch

本節以 helm 命令為例： https : //github.com/jaegertracing/helm-charts/tree/master/charts/jaeger#installing-the-chart-using-a-new-elasticsearch-cluster

Answer 5

對於使用 OpenTelemetry、Jaeger 和 Elasticsearch 的人來說，這里是方法。

請注意，所使用的圖像是jaegertracing/jaeger-opentelemetry-collector和jaegertracing/jaeger-opentelemetry-agent 。

version: '3.8'

services:
  collector:
    image: otel/opentelemetry-collector:latest
    command: ["--config=/conf/opentelemetry-collector.config.yaml", "--log-level=DEBUG"]
    volumes:
      - ./opentelemetry-collector.config.yaml:/conf/opentelemetry-collector.config.yaml
    ports:
      - "9464:9464"
      - "55680:55680"
      - "55681:55681"
    depends_on:
      - jaeger-collector

  jaeger-collector:
    image: jaegertracing/jaeger-opentelemetry-collector
    command: ["--es.num-shards=1", "--es.num-replicas=0", "--es.server-urls=http://elasticsearch:9200", "--collector.zipkin.host-port=:9411"]
    ports:
      - "14250"
      - "14268"
      - "9411"
    environment:
      - SPAN_STORAGE_TYPE=elasticsearch
      - LOG_LEVEL=debug
    restart: on-failure
    depends_on:
      - elasticsearch

  jaeger-agent:
    image: jaegertracing/jaeger-opentelemetry-agent
    command: ["--config=/config/otel-agent-config.yml", "--reporter.grpc.host-port=jaeger-collector:14250"]
    volumes:
      - ./:/config/:ro
    ports:
      - "6831/udp"
      - "6832/udp"
      - "5778"
    restart: on-failure
    depends_on:
      - jaeger-collector

  jaeger-query:
    image: jaegertracing/jaeger-query
    command: ["--es.num-shards=1", "--es.num-replicas=0", "--es.server-urls=http://elasticsearch:9200"]
    ports:
      - "16686:16686"
      - "16687"
    environment:
      - SPAN_STORAGE_TYPE=elasticsearch
      - LOG_LEVEL=debug
    restart: on-failure
    depends_on:
      - elasticsearch

  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch-oss:7.9.0
    environment:
      - discovery.type=single-node
    ports:
      - "9200/tcp"

那么只需要

docker-compose up -d

參考： https : //github.com/jaegertracing/jaeger/blob/master/crossdock/jaeger-opentelemetry-docker-compose.yml
