How to set tags for spans

[saritatewari4]

Hello all, I am instrumenting open telemetry with python. I am using baggage for sending extra fields while propagating. I want to set the baggage key as a tag key so that I can search in jaeger ui on the basis of tag. Please help, how I can configure it. This is my code:

`from opentelemetry import trace, baggage
from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import (
OTLPSpanExporter,
)
from opentelemetry.sdk.trace.export import SimpleSpanProcessor
from opentelemetry.sdk.trace import TracerProvider

def hello(**kwargs):

span_exporter = OTLPSpanExporter(
)
tracer_provider = TracerProvider()
trace.set_tracer_provider(tracer_provider)

span_processor = SimpleSpanProcessor(span_exporter)
tracer_provider.add_span_processor(span_processor)

Configure the tracer to use the collector exporter

tracer = trace.get_tracer_provider().get_tracer(name)
with tracer.start_span(name="root span" ) as root_span:
ctx = baggage.set_baggage("foo", "bar")

print(f"Global context baggage: {baggage.get_all()}")
print(f"Span context baggage: {baggage.get_all(context=ctx)}")

with tracer.start_as_current_span(name="root span") as root_span:
parent_ctx = baggage.set_baggage("context", "parent")
with tracer.start_as_current_span(
name="child span", context=parent_ctx
) as child_span:
child_ctx = baggage.set_baggage("context", "child")

print(baggage.get_baggage("context", parent_ctx))
print(baggage.get_baggage("context", child_ctx))
`

And this is my docker compose file:

version: "3" services: jaeger: image: jaegertracing/all-in-one:latest networks: - otelcol ports: - "16686:16686" - "14250" zipkin: image: openzipkin/zipkin-slim:latest networks: - otelcol hostname: zipkin ports: - "9412:9411" collector: image: otel/opentelemetry-collector-contrib:0.42.0 networks: - otelcol command: [ "--config=/otel-config.yaml" ] volumes: - ./otel-config.yaml:/otel-config.yaml hostname: collector ports: - "4317:4317" - "55680:55680" - "9411:9411" depends_on: - jaeger - zipkin networks: otelcol:
Check otel-config.yaml file:
