いつの間にかParameterStoreから最新のAMI-IDを取得できるようになっていたためメモ

各AWSサービスで使用できるPublicパラメータというものがParameterStoreで公開されている。
ParameterStoreからは以下の用に各サービスに対応するパラメータが取得できる

  • ami-amazon-linux-latest

  • ami-windows-latest

  • ami-macos-latest

  • appmesh

  • aws-for-fluent-bit

  • bottlerocket

  • canonical

  • cloud9

  • datasync

  • debian

  • ecs

  • eks

  • freebsd

  • global-infrastructure

  • marketplace

  • storagegateway

各サービスのパラメータのパスは aws ssm get-parameters-by-path --path /aws/service/list で取得できる。

AMI-IDの取得

今回はAMI-IDを取得する。

amiでgrep
C:\Users\szk>aws ssm get-parameters-by-path --path /aws/service/list | grep ami
            "Name": "/aws/service/list/ami-amazon-linux-latest",
            "Value": "/aws/service/ami-amazon-linux-latest/",
            "ARN": "arn:aws:ssm:ap-northeast-1::parameter/aws/service/list/ami-amazon-linux-latest",
            "Name": "/aws/service/list/ami-windows-latest",
            "Value": "/aws/service/ami-windows-latest/",
            "ARN": "arn:aws:ssm:ap-northeast-1::parameter/aws/service/list/ami-windows-latest",

サービスごとのパラメータのグループのリストが出るので、取得したいパラメータを更に取得
