AWSのRegion間で共通なKey Pairを用いる

More than 5 years have passed since last update.

AWS EC2のKey PairはRegion間で別管理になるが、ImportすることでRegion間で共通なKey Pairを利用出来る。
ここではManagement ConsoleでRegion間で共通なKey Pairを用いるための手順をメモする。

利用手順

  • あるRegionのEC2 Management ConsoleのKey PairsでCreate Key Pairし秘密鍵をダウンロードする
  • ローカル環境で秘密鍵から公開鍵を生成する
 $ ssh-keygen -y -f [ダウンロードした秘密鍵]
  • 別のRegionのEC2 Management ConsoleのKey PairsでImport Key Pairする

    • Keypair Nameには適当な名前を入れる
    • Public Key contentsには1つ前の手順で表示された文字列を入れる
  • ImportしたKeyを使用したEC2にダウンロードした秘密鍵でアクセス出来る
