cannot build on 'ssh://root@nix-docker' #29
Description
I'm following the macOS-nix-docker guide here. I installed nix-darwin with
nix-build https://github.com/LnL7/nix-darwin/archive/master.tar.gz -A installer
./result/bin/darwin-installerand I've set
nix.distributedBuilds = true;
nix.buildMachines = [ {
hostName = "nix-docker";
sshUser = "root";
sshKey = "/etc/nix/docker_rsa";
systems = [ "x86_64-linux" ];
maxJobs = 2;
} ];and
services.nix-daemon.enable = true;darwin-rebuild switch:
darwin-rebuild switch

I can ssh as root to the docker builder, but running the test build fails with
$ nix-build -E 'with import <nixpkgs> { system = "x86_64-linux"; }; hello.overrideAttrs (drv: { rebuild = builtins.currentTime; })'

cannot build on 'ssh://root@nix-docker': cannot connect to 'root@nix-docker': ssh: Could not resolve hostname nix-docker: nodename nor servname provided, or not known
error: a 'x86_64-linux' is required to build '/nix/store/8f0dgnis487dsr6xz0d9jyqrhqqvfshb-hello-2.10.drv', but I am a 'x86_64-darwin'Is this an issue with the nix-daemon? How can I get it to talk to the docker container?
