The propagators for the ``opentelemetry.propagators.composite.CompositePropagator`` can be defined via configuration in the ``OTEL_PROPAGATORS`` environment variable. This variable should be set to a comma-separated string of names of values for the ``opentelemetry_propagator`` entry point. For example, setting ``OTEL_PROPAGATORS`` to ``tracecontext,baggage`` (which is the default value) would instantiate ``opentelemetry.propagators.composite.CompositePropagator`` with 2 propagators, one of type ``opentelemetry.trace.propagation.tracecontext.TraceContextTextMapPropagator`` and other of type ``opentelemetry.baggage.propagation.W3CBaggagePropagator``. Notice that these propagator classes are defined as ``opentelemetry_propagator`` entry points in the ``pyproject.toml`` file of ``opentelemetry``. Example:: import flask import requests from opentelemetry import propagate PROPAGATOR = propagate.get_global_textmap() def get_header_from_flask_request(request, key): return request.headers.get_all(key) def set_header_into_requests_request(request: requests.Request, key: str, value: str): request.headers[key] = value def example_route(): context = PROPAGATOR.extract(get_header_from_flask_request, flask.request) request_to_downstream = requests.Request("GET", "http://httpbin.org/get") PROPAGATOR.inject( set_header_into_requests_request, request_to_downstream, context=context, ) session = requests.Session() session.send(request_to_downstream.prepare()) .. _Propagation API Specification: https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/context/api-propagators.md ) getLogger)environ)Context)OTEL_PROPAGATORS) compositetextmapNcV^8dQhR\PR\R,R\P\P,R\/#)carriercontextNgetterreturn)rCarrierTrGetter)formats"t/var/www/html/mycamper/aliexpress-site/backend/venv/lib/python3.14/site-packages/opentelemetry/propagate/__init__.py __annotate__rBsOII   I t^I NN7++ ,I Ic8\4PWVR7#)a.Uses the configured propagator to extract a Context from the carrier.
