ネットワーク図(nwdiag)

nwdiagは、小宮健(Takeshi KOMIYA)によって作られた、ネットワーク図を生成するためのツールです。

その文法はわかりやすくシンプルなので、PlantUMLにも組み込まれました。 以下に、公式サイトのサンプルと同等の図を載せています。

シンプルなネットワーク図

ネットワークの定義

ネットワークとグループに対する拡張文法

ネットワーク

ネットワーク、ネットワーク要素に対して、次の項目が設定可能です:
  • アドレス (コンマ,区切り)
  • 説明
  • 形状

🎉 Copied!
@startuml
nwdiag {
  network Sample_front {
    address = "192.168.10.0/24"
    color = "red"

    // define group

      web01 [address = ".1, .2", shape = "node"]
      web02 [address = ".2, .3"]
    }

    color = "palegreen"
    web01 [address = ".1"]
    web02 [address = ".2"]
    db01 [address = ".101", shape = database ]
    db02 [address = ".102"]

    // define network using defined nodes
    group db {
      db01;
      db02;
    }
  }
}
@enduml

グループ

グループに対して、次の項目が設定可能です:

🎉 Copied!
@startuml
nwdiag {
  group {
    color = "#CCFFCC";
    description = "Long group description";

    web01;
    web02;

    web02;
    db01 [address = ".101", shape = database];
  }
}
@enduml

[Ref. QA-12056]

スプライトの使用

標準ライブラリやその他のライブラリに含まれる、あらゆるスプライト(アイコン)を使用できます。

スプライトは<$sprite>の記法を使います。\nで改行できます。また、その他のCreole記法も使用できます。

🎉 Copied!
@startuml
!include <office/Servers/application_server>
!include <office/Servers/database_server>

nwdiag {
  network dmz {
      address = "210.x.x.x/24"

      // set multiple addresses (using comma)
      web01 [address = "210.x.x.1, 210.x.x.20",  description = "<$application_server>\n web01"]
      web02 [address = "210.x.x.2",  description = "<$application_server>\n web02"];
  }
  network internal {
      address = "172.x.x.x/24";

      web01 [address = "172.x.x.1"];
      web02 [address = "172.x.x.2"];
      db01 [address = "172.x.x.100",  description = "<$database_server>\n db01"];
      db02 [address = "172.x.x.101",  description = "<$database_server>\n db02"];
  }
}
@enduml

[Ref. QA-11862]

OpenIconicの使用

ネットワークまたはノードの説明で、OpenIconicのアイコンを使用することもできます。

<&icon>の記法でアイコンを表示します。<&icon*n>でサイズをn倍にします。\nで改行できます:

🎉 Copied!
@startuml

nwdiag {
  group nightly {
    color = "#FFAAAA";
    description = "<&clock> Restarted nightly <&clock>";
    web02;
    db01;
  }
  network dmz {
      address = "210.x.x.x/24"

      user [description = "<&person*4.5>\n user1"];
      // set multiple addresses (using comma)
      web01 [address = "210.x.x.1, 210.x.x.20",  description = "<&cog*4>\nweb01"]
      web02 [address = "210.x.x.2",  description = "<&cog*4>\nweb02"];

  }
  network internal {
      address = "172.x.x.x/24";

      web01 [address = "172.x.x.1"];
      web02 [address = "172.x.x.2"];
      db01 [address = "172.x.x.100",  description = "<&spreadsheet*4>\n db01"];
      db02 [address = "172.x.x.101",  description = "<&spreadsheet*4>\n db02"];
      ptr  [address = "172.x.x.110",  description = "<&print*4>\n ptr01"];
  }
}

複数のネットワークに一つのノードを定義

異なる二つ以上のネットワークに同一のノードを使用することができます。この場合、nwdiagではネットワークの上をジャンプする線が描画されます。

🎉 Copied!
@startuml
nwdiag {
  // define group at outside network definitions
  group {
    color = "#7777FF";

    web01;
    web02;

  }

  network dmz {
    color = "pink"

    web01;
    web02;
  }

  network internal {
    web01;
    web02;
    db01 [shape = database ];
  }

  network internal2 {
    color = "LightBlue";

    web01;
    web02;
    db01;
  }

}

ピア接続

ピア接続は、二つのノード間を単純につなぐものです。この場合は、横長の「バス線」ネットワークは使用されません。

🎉 Copied!
@startuml
nwdiag {
  inet [shape = cloud];
  inet -- router;

  network {
    router;
    web01;
    web02;
  }
}
@enduml

ピア接続とグループ

グループ無し

🎉 Copied!
@startuml
nwdiag {
    internet [ shape = cloud];
    internet -- router;

    network proxy {
        router;
        app;
    }
    network default {
    	app;
        db;
    }
}
@enduml

1番目にグループを記述

🎉 Copied!
@startuml
nwdiag {
    internet [ shape = cloud];
    internet -- router;

    group {
      color = "pink";
      app;
      db;
    }

    network proxy {
        router;
        app;
    }

    network default {
    	app;
        db;
    }
}
@enduml

2番目にグループを記述

🎉 Copied!
@startuml
nwdiag {
    internet [ shape = cloud];
    internet -- router;

    network proxy {
        router;
        app;

    group {
      color = "pink";
      app;
      db;
    }

    network default {
    	app;
        db;
    }
}
@enduml

FIXME
proxyから'db'へ線が引かれてしまいます。('db'は'default network'にしかつながっていないはずです。) [グループ無しの例を参照]

3番目にグループを記述

@startuml
nwdiag {
    internet [ shape = cloud];
    internet -- router;

    network proxy {
        router;
