 - **Items Service**: Sends traces via OpenTelemetry Protocol (OTLP)
-- **Jaeger Collector**: Receives traces on port 4318 (HTTP) and 4317 (gRPC)
+- **Jaeger v2**: All-in-one binary that includes collector, query, and UI
+- **OTLP Receivers**: Receives traces on port 4318 (HTTP) and 4317 (gRPC)
 - **Jaeger UI**: Web interface for viewing and analyzing traces

+**Configuration (Jaeger v2):**
+Jaeger v2 uses command-line arguments instead of environment variables:
 ```yaml
-env:
-  - name: COLLECTOR_OTLP_ENABLED
-    value: "true"
-  - name: QUERY_BASE_PATH
-    value: "/jaeger"
-  - name: SPAN_STORAGE_TYPE
-    value: "memory"
-  - name: MEMORY_MAX_TRACES
-    value: "10000"

+  - "--set=extensions.jaeger_query.base_path=/jaeger"
 ```
 
+**Note:** Jaeger v2 uses the OpenTelemetry Collector configuration format. OTLP is enabled by default in all-in-one mode.
