メモ

• ChaliceはデフォルトだとAWS-SDKでリソースを作るだけである
• CloudFormationするには chalice package などして色々する必要がある
  • AWS CloudFormation Support — AWS Chalice
  • Deploying AWS Chalice application using AWS Cloud Development Kit | AWS Developer Blog
• deployed/dev.json に書いてある以外にもリソースは生成されている
  • LambdaのCloudWatchLogsなどはつくられる
• ローカルでちょっと確認したいときは $ chalice local が使える
