To Reproduce

Needs #38.

  services.trustix = {
    enable = true;

    signers.davidak = {
      type = "ed25519";
      ed25519 = {
        private-key-path = "/var/trustix/keys/private";
      };
    };

    publishers = [
      {
        signer = "davidak";
        protocol = "nix";
        publicKey = {
          type = "ed25519";
          key = "*****";
        };
      }
    ];

    subscribers = [
      {
        protocol = "nix";
        publicKey = {
          type = "ed25519";
          key = "*****";
        };
      }
    ];

    deciders.nix = {
      engine = "percentage";
      #percentage.minimum = 66;
      percentage.minimum = 0;
    };

    # A remote can expose many logs and they are not neccesarily created by the remote in question
    remotes = [
      #"grpc+http://127.0.0.1"
      #"https://cache.nixos.org"
      "unix:///run/trustix-daemon.socket"
    ];

  };

  # Push local builds via the post-build hook
  services.trustix-nix-build-hook = {
    enable = true;
    logID = "*****";
  };

  # Enable the local binary cache server
  services.trustix-nix-cache = {
    enable = true;
    private-key = "/var/trustix/keys/cache-private-key.pem";
    listen = "0.0.0.0";
    port = 9001;
    openFirewall = true;
  };

  # Configure Nix to use it
  nix = {
    binaryCaches = [
      "http://127.0.0.1:9001"
    ];
    binaryCachePublicKeys = [
      "binarycache.example.com:*****"
    ];
  };

Expected behavior

decide should work according to the configuration.

i had write the config differently than the documentation says to avoid errors. this is the only way i found works without errors

Environment
