tilt ci 

works as expected with the same downloaded CRDs list:

grep --include='*.yaml' --include='*.yml' -rEil '\bkind[^\w]+CustomResourceDefinition\s*$'

  if len(files) != 0:
        local_resource(name+'-install', cmd='kubectl apply -f %s' % " -f ".join(files), deps=files)  # we can wait/depend on this, but it won't cause a proper uninstall
        k8s_yaml(files)  # this will cause a proper uninstall, but we can't wait/depend on it

        # TODO: Figure out how to avoid another named resource showing up in the tilt HUD for this waiter
        local_resource(name+'-ready', resource_deps=[name+'-install'], cmd='kubectl wait --for=condition=Established crd --all')  # now we can wait for those crds to finish establishing

Allow duplicates may have to be propagated to the place where CRDs are installed: https://github.com/tilt-dev/tilt-extensions/blob/master/helm_remote/Tiltfile#L216 - still not clear why this works on MacOSx though.

[nicks]

ya, we'd accept a pr to propagate allow duplicates to install_crds

as for why it works on macos -- my guess is that you've got a different version of grep on your macos box, and so the install_crds function isn't properly filtering the CRDs. The grep ecosystem on macos is really fractured. does it fail if you install the coreutils version of grep (brew install coreutils)?
