AWS-SAA: SAML 2.0 シングルサインオン

一発でリソースを削除する

terraform destory では削除に失敗したりするのがある。

いちいちコンソールに飛ぶのはだるいので、なるべく多くのリソースを削除するのにいい方法がないかを調べ、実験する。

コンテナイメージ

よく使う言語・フレームワークについては、コンテナイメージの理想系的なのを持っておきたい。

Tips

複数行コメント

variable plaintext_params {
  type        = map(string)
  default     = {}
  description = <<EOF
  Lambda@Edge does not support env vars, so it is a common pattern to exchange Env vars for values read from a config file.
  So instead of using env vars like:
  `const someEnvValue = process.env.SOME_ENV`
  you would have lookups from a config file:
  ```
  const config = JSON.parse(readFileSync('./config.json'))
  const someConfigValue = config.SomeKey
  ```
  Compared to var.ssm_params, you should use this variable when you have non-secret things that you want very quick access
  to during the execution of your lambda function.
