AzureのARMTemplateでApplicationGatewayの静的Webサイトやってみた
AWSでもGCPでも標準のIaCやってみたのでAzureでも やらなきゃダメでしょということでAzureのIaCであるARMTemplate試してみました。
構成としてはApplicationGateway+BlobStorageので、ついでにDNSもARMTemplateやってみました。SSL証明書はZEROSSLで発行し、ドメインはfreenomで発行しています。
ARMTemplate自体はAWSとかGCPと違ってJSON形式みたいですが、今後はBicepとかいうやつが標準になる様です。ではいってみましょう。
◆作業およびARMテンプレート
1.事前準備
#PowerShellインストール $ mkdir armtemplate $ cd armtemplate $ sudo apt-get update $ sudo apt-get install -y wget apt-transport-https software-properties-common $ wget -q https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb $ sudo dpkg -i packages-microsoft-prod.deb $ sudo apt-get update $ sudo apt-get install -y powershell $ pwsh #テストツールダウンロード PS /home/user/armtemplate> cd armtemplate PS /home/user/armtemplate> git clone https://github.com/Azure/arm-ttk.git
2.DNS
・ARMテンプレート
$ vi dns__template.json
------------------------------------------------ { "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#", "contentVersion": "1.0.0.0", "metadata": { "_generator": { "name": "bicep", "version": "0.5.6.12127", "templateHash": "17563758552659577113" } }, "parameters": { "zoneName": { "type": "string", "defaultValue": "[format('{0}.azurequickstart.org', uniqueString(resourceGroup().id))]", "metadata": { "description": "The name of the DNS zone to be created.

とりあえず3大クラウドのIaCツールを試してみての感想ですが、どこも似てるといえば似ているかなぁという感じです。AWSとGCPがYAMLやJinjaで分かりやすいのに対してJSONというところで少し抵抗感が大きかったです。しかしまぁ、いずれも同じような仕組みなのでどれか1個でもやったことある人ならすぐになれるかと思います。自分は弱いのでダメダメですが、、、。
AWSでCDKとかPulumiとかが流行りだしているので潮流的にプログラマブルにいじくれるようにってことになっているんでしょうねぇ。僕みたいなプログラム苦手な人間には非常に生きづらい世の中になりそうですね。
一応、GitHubに上げています。
