FWIW, I packaged Envoy for NixOS in an evening: https://github.com/NixOS/nixpkgs/blob/dab3272f47f13c2a7442e3aec6b4b5bcc1bfd907/pkgs/tools/networking/envoy/defau

FWIW, I packaged Envoy for NixOS in an evening: https://github.com/NixOS/nixpkgs/blob/dab3272f47f13c2a7442e3aec6b4b5bcc1bfd907/pkgs/tools/networking/envoy/default.nix https://github.com/NixOS/nixpkgs/blob/dab3272f47f13c2a7442e3... That nets you $ nix-build -A envoy ... and then you're done. Of course, we have a CI server that builds our packages regularly, so it's likely you wouldn't even need to build from source (though you certainly could, if desired).
