AWS Lambdaでコンテナ(インスタンス)を再利用させないようにする

Last updated at Posted at 2023-02-23

Lambdaは前回実行から310秒以内に実行するとコンテナを再利用します。sleepさせて意図的に再利用できないようにできます。汚れた環境で実行したくない場合に便利です

検証方法

sleep 320にするとログストリームが増え、新しいコンテナ(インスタンス)で実行されていることがあわります

for i in `seq 10`; do curl https://.lambda-url.ap-northeast-1.on.aws/; sleep 320; done

sleep 300にするとログストリームが増えず、1つのコンテナ(インスタンス)で実行されていることがあわります

for i in `seq 10`; do curl https://.lambda-url.ap-northeast-1.on.aws/; sleep 300; done
