将Scala部署到NixOps

我尝试使用NixOS在NixOS下使用Scala中的Play 2 Web服务部署VirtualBox。

我有这台机器:

{
  backoffice = {
    deployment.targetEnv = "virtualbox";
    deployment.virtualbox.memorySize = 1024; # MB
  };
}

在这个逻辑网络上:

{
  network.description = "Test";

  backoffice =
    { config, pkgs, ... }:
    let
        callPackage = pkgs.lib.callPackageWith (pkgs);
        Back = callPackage ../pkgs/Backoffice.nix {};
    in {
        environment.systemPackages = [
          pkgs.jdk
          Back
        ];

        systemd.services.backoffice = {
            description = "Backoffice";
            # Start the service after the network is available
            after = [ "network.target" ];
            script = "${Back}/webapps/bin/play-back";
            serviceConfig = {
              Restart = "always";
            };
          };

          networking.hostName = "backoffice";
          networking.firewall.allowedTCPPorts = [ 80 ];
          system.stateVersion = "15.09";
    };
}

Backoffice.nix是这个派生的地方:

with import <nixpkgs> {};

stdenv.mkDerivation {
  name = "Backoffice";
  src = ../../back;
  buildInputs = [ sbt ];
  buildPhase = let
        sbtBootDir = "./.sbt/boot/";
        sbtIvyHome = "/var/tmp/`whoami`/.ivy";
        sbtOpts = "-XX:PermSize=190m -Dsbt.boot.directory=${sbtBootDir} -Dsbt.ivy.home=${sbtIvyHome}";
    in ''
        mkdir -p ${sbtBootDir}
        mkdir -p ${sbtIvyHome}
        sbt ${sbtOpts} stage
    '';

  installPhase = ''
    mkdir -p $out/webapps
    cp -ra ./target/universal/stage/* $out
  '';
}

VM启动并部署正常。但是当我进入它时,我无法在里面找到我的后台派生。

如果我在当地做

nix-build Backoffice.nix

...它构建没有问题,我可以在我的开发机器上的/ nix / store中找到派生。

在VM中,有一个/nix/store/shaXXX-backoffice.service,所以它有点工作。但由于后台派生不存在,它什么都不做。

有人能告诉我我做错了吗?

答案 0 :(得分:2)

发现它! systemd.services.backoffice需要什么:

path = [ "${pkgs.jdk.home}" "${pkgs.gawk}" ];

Play Framework脚本正在使用它们来启动它自己。
