CloudFormation

CloudFormation の勉強のために作ってみました。どうせつくるなら使える構成なるように工夫してみました。結局 user-data のお化けになってしましましたね。push 型デプロイの限界ですね。やっぱり CMDB というか、chef, puppet で push+pull でデプロイするのがいいですねぇ。CloudFormation はその意味では有用なので勉強しナイト。

ubuntu + WordPress All-In-One CloudFormation Template

ubuntu Generic AMI から debian/ubuntu のパッケージ管理の流儀にのっとって構成するようにしました。また EC2 特有の IP address 空間に対応する為に Split DNS を構成しています。WordPress については、現在の ubuntu パッケージが古いので、パッケージは導入せず、debian のお作法は踏襲して独自に構成しています。User-data の途中のバイナリーデータは Split DNS の構成ファイル群を tar で固めたものです。
