如何使用elasticsearch配置Jaeger？

Question

我已经尝试过执行这个docker命令来使用elasticsearch设置Jaeger代理和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 

但是这个命令给出了下面的错误。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

正如我在上面对OP的第一个答复的评论中提到的那样，我在运行对接器时遇到了一个错误--完全按照给定的方式编写：

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

我认为这个CLI标志已经被Jaeger的人们反对，因为这个答案是写出来的。所以我在jaeger特工的文档里找了一下：

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

我做了一些小小的修改：

1. 我将端口范围"14250:14250"添加到jaeger-收集器端口。
2. 我用：command: ["--reporter.grpc.host-port=jaeger-collector:14250"]更新了jaeger命令输入。
3. 最后，我更新了image标记中的ellastic版本，将其更新为当前可用的最新版本(尽管我怀疑这是必需的)。

更新的船坞-Compose.yaml：

如果Jaeger需要在Kubernetes集群中设置为一个舵机图表，可以使用以下方法：https://github.com/jaegertracing/helm-charts/tree/master/charts/jaeger，它可以将Elasticsearch或Cassandara作为存储后端。这只是一个正确的价值被传递到图表中的问题：

storage:
  type: elasticsearch
