パブリックパラメータを利用して各OSの最新のAMI IDを取得してみる

本エントリについて

AWS Systems Manager (SSM) パラメータストアのパブリックパラメータを利用して、Debian、Ubuntu、AmazonLinuxの最新のAMI IDを取得してみます。
ここではAWS CLIを利用します。

パブリックパラメータ一覧

まず、どのようなサービスのパブリックパラメータがあるのか、リストを取得してみます。

$ aws ssm get-parameters-by-path --path /aws/service/list --region ap-northeast-1 --query Parameters[].Value
[
    "/aws/service/appmesh/",
    "/aws/service/aws-storage-gateway-latest/",
    "/aws/service/bottlerocket/",
    "/aws/service/canonical/",
    "/aws/service/cloud9/",
    "/aws/service/datasync/",
    "/aws/service/debian/",
    "/aws/service/ecs/",
    "/aws/service/eks/",
    "/aws/service/freebsd/",
    "/aws/service/ami-amazon-linux-latest/",
    "/aws/service/ami-windows-latest/",
    "/aws/service/aws-for-fluent-bit/",
    "/aws/service/global-infrastructure/",
    "/aws/service/marketplace/",
    "/aws/service/redhat/",
    "/aws/service/storagegateway/",
    "/aws/service/suse/"
]

Debian

Debian に関するパラメータは /aws/service/debian/ にあるようですので、配下の情報を取得してみます。
(数十行ありますので、出力は途中で割愛します)
パスを見ればどんなバージョンなのか分かる形になっています。

$ aws ssm describe-parameters --parameter-filters "Key=Name, Option=BeginsWith, Values=/aws/service/debian" --region ap-northeast-1 --query Parameters[].Name
[
    "/aws/service/debian/daily/11/20220711-1073/amd64",
    "/aws/service/debian/daily/11/latest/amd64",
    "/aws/service/debian/daily/bullseye/20220711-1073/amd64",
    "/aws/service/debian/daily/bullseye/latest/amd64",

AMI IDの取得

最新といいつつ、ここでは Debian buster(amd64) についての 最新のAMI IDを取得してみます。
