Diagram as CodeでCloudFormationテンプレートからDiagramを生成してみる

AWS

Junichi Hashimoto

サンプルのCloudFormationテンプレートをダウンロードする。

curl -o ./vpc-subnet-ec2-cfn.yaml https://raw.githubusercontent.com/awslabs/diagram-as-code/refs/heads/main/examples/vpc-subnet-ec2-cfn.yaml

Junichi Hashimoto

テンプレートからDiagramを生成する。

awsdac ./vpc-subnet-ec2-cfn.yaml --cfn-template
# [Completed] AWS infrastructure diagram generated: output.png

テンプレート -> Yamlファイル -> Diagramを試してみる。中間ファイルであるYamlファイルを編集することにより、Diagramをカスタマイズできる。

まずYamlファイルを生成する。

awsdac ./vpc-subnet-ec2-cfn.yaml --cfn-template --dac-file
[Completed] dac (diagram-as-code) data written to output.yaml
[Completed] AWS infrastructure diagram generated: output.png
