AWS Cloud9とVS Code Remote SSHを組み合わせて使ってみた

# 通常ユーザーは ec2-user ( /home/ec2-user/.ssh/authorized_keys )
$ cat ~/.ssh/authorized_keys
# Important
# ---------
# The following public key is required by Cloud9 IDE
# Removing this key will make this EC2 instance inaccessible by the IDE
#
cert-authority ssh-rsa XXXXX・・・（中略）・・・XXXXX xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@cloud9.amazon.com

#
# Add any additional keys below this line
#

# ssh-keygen -y で秘密鍵から公開鍵を読みだす
ssh-keygen -y -f "秘密鍵のパス"

# Cloud9 IDE内で実行してください

# 最初に元スクリプトを移動してバックアップ
sudo mv ~/.c9/stop-if-inactive.sh ~/.c9/stop-if-inactive.sh-SAVE
# AWSで用意してくれたスクリプトをダウンロード
