It takes an IAgent. So one can do: network_kubernetes(base_url=url, agent=Agent(contextFactory=...)) Does that approach fit with any emerging conventions for exposing this kind of functionality? I'd be happy to adapt it if there's a better pattern. Also note that it's common for Kubernetes to be deployed with a self-signed or other non-cartel certificate. So even the API in the example, network_kubernetes_from_context, doesn't trust the usual web-oriented collection of CAs. It only respects the certificate found in the local Kubernetes configuration. This means that there's another way to control this - edit ~/.kube/config and put the desired CA certificate there. > Here is an example of txkube usage, taken from the README: > > from __future__ import print_function > from twisted.internet.task import react > > from txkube import v1, network_kubernetes_from_context > > @react > > > btw, don't think I didn't notice this > <https://github.com/twisted/twisted/pull/646#discussion_r96104930>... > 😂 Jean-Paul > > > def main(reactor): > k8s = network_kubernetes_from_context(reactor, u"minikube") > client = k8s.client() > d = client.list(v1.Namespace) > d.addCallback(print) > return d > > You can download txkube from PyPI <https://pypi.python.org/pypi>. > You can contribute to its development on GitHub > <https://github.com/LeastAuthority/txkube>. > > Thanks to Least Authority Enterprises <https://leastauthority.com/> for > sponsoring this development. > > > Thanks, LAE! > > -glyph > > > _______________________________________________ > Twisted-Python mailing list > Twisted-Python@twistedmatrix.com > http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python > >
