Hi @tsunamaru. The Prometheus storage is used for the metrics, not for the traces. You need to specify the metrics storage in the .spec.metricsStorage field. There is an example in the examples folder:

apiVersion: jaegertracing.io/v1
kind: "Jaeger"
metadata:
  name: "my-jaeger"
spec:
  strategy: allInOne
  allInOne:
    options:
      log-level: debug
      query:
        base-path: /jaeger
      prometheus:
        server-url: "http://prometheus:9090"
    metricsStorage:
      type: prometheus
  storage:
    options:
      memory:
        max-traces: 100000
