## 필요하면 IAM정책 추가

저는 풀권한이 있어서 추가 설정은 안했습니다.

 

 

사용자에게 EC2 Instance Connect 엔드포인트를 사용한 인스턴스 연결 허용

//해당 json코드에서 빨강색으로 표시된 부분만 수정해주시면 됩니다.

EX)
region : ap-northeast-2     //서울
access-ID : 73532934xxxx
eice-xxxxxxxxxxx : 엔드포인드 ID

// 접속할 포트
ec2-instance-connect:remotePort": "22"

// 접속할 IP -> 저는 VPC 대역을 넣어줌
"ec2-instance-connect:privateIpAddress": "10.10.0.0/27"

// 이 부분은 AWS의 EC2 Instance Connect 서비스에서 SSH 연결이 유지되는 최대 시간을 설정, 저는 60초
"ec2-instance-connect:maxTunnelDuration": "60"
