Building Zeek with nix-shell(shell mode)

Building zeek with plugins

mkZeekPlugins = inputs.zeek2nix.lib.zeekWithPlugins {
  package = inputs.zeek2nix.packages.${system}.zeek-latest;
  plugins = [
    {
      src = inputs.zeek2nix.lib.nixpkgs.zeek-sources.zeek-community-id;
    }
  ];
  };

Testing your Zeek Plugin src with Nix-CI

mkZeekPluginCI = nixpkgs.zeekPluginCi {
    plugins = [
      {
        src = inputs.zeek2nix.lib.nixpkgs.zeek-sources.zeek-netmap;
      }
    ];
    buildInputs = [inputs.zeek2nix.lib.nixpkgs.netmap];
  };

Deploying Zeek with NixOS (flakes feature)

{
  inputs =
    {
      zeek-nix = {
        url = "github:hardenedlinux/zeek-nix/main";
        inputs.nixpkgs.follows = "nixos";
      };
      "..."
        };
        outputs = { self, zeek-nix, nixpkgs, ... }: {
        nixosConfigurations.myConfig = nixpkgs.lib.nixosSystem {
          system = "...";

          modules = [
            zeek-nix.nixosModules.zeek
            ({ ... }: {
              services.zeek = {
                enable = true;
                standalone = true;
                interface = "eno1";
                listenAddress = "localhost";
                package = pkgs.zeekWithPlugins {
                  package = pkgs.zeek-latest;
                  plugins = [
                    {
                      src = pkgs.zeek-sources.zeek-community-id;
                    }
                  ];
                };

                privateScript = ''
                  @load /home/gtrun/project/hardenedlinux-zeek-script/scripts/zeek-query.zeek
                  @load /home/gtrun/project/hardenedlinux-zeek-script/scripts/log-passwords.zeek
                '';
              };
            })
          ];
        };
      };
    }

creating the zeek dynamic dir to /var/lib/zeek

[2020-10-09 Fri 19:35] <- sudo bash ./pre-run-zeekctl.sh

Optional: using cachix to speed up binary build

nix-env -iA cachix -f https://cachix.org/api/v1/install
cachix use zeek
