テキスト(コード)で、ネットワーク構成図を描く方法

考察

GMOペパボ Documentation as Code

  • 「ndiag」というGMOペパボのOyamaさんのツールを利用しているようです。

nwdiag

  • Python製
  • Apache License 2.0
  • もっとも一般的な論理ネットワーク構成図に近いです。

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

      web01 [address = "210.x.x.1"];
      web02 [address = "210.x.x.2"];
  }
  network internal {
      address = "172.x.x.x/24";

      web01 [address = "172.x.x.1"];
      web02 [address = "172.x.x.2"];
      db01;
      db02;
  }
}
