I've been developing the streamer functionality, and it's correctly working (in my testing) as driven from the Remote.policy attribute. It correctly works with 'immediate', 'on_demand', and 'cache_only'. Read more about the expected behaviors in the epic [0].
# Try it out! Here is the core commit needed: https://github.com/pulp/pulp/pull/3738 Here is the streamer you should pip install from master: https://github.com/bmbouter/pulp_streamer Here is what it looks like to port a plugin using DeclarativeVersion, e.g. pulp_file to support lazy: https://github.com/pulp/pulp_file/pull/132 You'll need to configure Pulp's webserver for streaming. I did this by exporting an environment var to dynaconf in the same bash environment as my django run server. Specifically I configured Pulp to redirect to port localhost:8080/streamer/ with this command: export PULP_CONTENT='@json {"HOST": null, "WEB_SERVER": "django", "REDIRECT": {"ENABLED": true, "PORT": 8080, "HOST": "localhost", "PATH_PREFIX": "/streamer/"}}' Then I run the streamer (after pip installed) with gunicorn which you also need to pip install. Run it with: gunicorn pulpcore.streamer:server --bind localhost:8080 --worker-class aiohttp.GunicornWebWorker -w 2 Then sync a pulp_file repo with policy='on_demand' or policy='cache_only' and see how Pulp behaves. Feedback, ideas, concerns are welcome in any form. Note this is still rough, and the following are known things to be done: * fix tests to get Travis passing * docs for the streamer and for pulpcore * an installer role to install the streamer * integration with squid to cache lots of data at the streamer * transfer the pulp_streamer to the Pulp org on github * publish an initial release to PyPI for users to use it * write a blog post about porting to it and using it * make a demo [0]: https://pulp.plan.io/issues/3693 Thanks!
