After reviewing the NixOps source code, I'm pretty sure that GCE doesn't support the privateIPv4 value. I've opened issue #309 <https://github.com/NixOS/nixops/issue/309> for this. I'm happy to try to cargo cult some code to add support for privateIPv4 on GCE, but I'm not sure I'm the best person to do this. -- Russell O'Connor <http://r6.ca/> ``All talk about `theft,''' the general counsel of the American Graphophone Company wrote, ``is the merest claptrap, for there exists no property in ideas musical, literary or artistic, except as defined by statute.'' _______________________________________________ nix-dev mailing list [email protected] http://lists.science.uu.nl/mailman/listinfo/nix-dev
