jaeger-query: v1.60.0

Jaeger's official documentation does not give the deployment method of jaeger-query. CRD resources given to Jaeger-operator: Jaeger’s three deployment methods: allInOne, production, streaming.

Therefore, an example of jaeger-query deployment needs to be given.

The following is the yaml of my Deployment for deploying jaeger-query

If you are using version 1.60.0 of jaeger, you need to modify the environment variables

env:
    - name: SPAN_STORAGE_TYPE
      value: grpc  #not grpc-plugin

When quickwit is deployed in distributed form using helm, the environment variables : GRPC_STORAGE_SERVER

env:
  - name: GRPC_STORAGE_SERVER
    value: quickwit-searcher:7281

The document gives the configuration when deploying in allInOne mode, but does not give how to configure it when helm is deployed, and many services have the 7281 port exposed, making it difficult to tell which one to use.

Awesome! thanks @liuxuzxx!

let's add this to the documentation.

FYI, you don't need the jaeger-query deployment if you use Grafana and the Jaeger plugin.

Okay, thank you, I will try use Grafana and the Jaeger plugin

But in that case you need to have rewrite path proxy in between. As Grafan plugin do not support path prefix.

At least I wasn't able to make it working. With a simple envoy proxy between them everything working fine.
