In the inspected Load Test Start flow (load-test-start.yml → start.sh), Terraform returns once the EC2 instance is running, not when this user-data script has downloaded and restored the S3 dump. start.sh then immediately restarts stage against the new private IP and reports the environment ready, while the database may still be unavailable; user-data failures are likewise never surfaced. Poll cloud-init status --wait or the generated ready marker through SSM before switching stage or completing the workflow.
Useful? React with 👍 / 👎.

반영했습니다. scripts/load_test/start.sh에서 Terraform apply 이후 load-test DB 인스턴스의 SSM online 상태를 먼저 기다리고, cloud-init status --wait --long 및 /opt/solid-connection/load-test-db-ready marker 존재 확인이 성공한 뒤에만 stage 전환을 진행하도록 했습니다. 실패 시 cloud-final 로그를 출력하고 workflow가 실패하도록 처리했습니다.

SSM agent 설정을 /etc/amazon/ssm/amazon-ssm-agent.json 에 기록하는 부분은 snap 으로 설치된 agent 에서는 반영되지 않을 것 같습니다!
바로 아래 81번째 줄에서 snap.amazon-ssm-agent.amazon-ssm-agent.service 를 먼저 확인하고 있는데, snap 설치본은 이 경로가 아니라 /var/snap/amazon-ssm-agent/current/amazon-ssm-agent.json 을 읽습니다. load_test_db_ami_id 기본값인 ami-0501a03cd31b53e82 가 ubuntu 24.04 기반이라 agent 가 snap 으로 사전 설치되어 있을 가능성이 높아 보입니다.
이 경우 주입한 엔드포인트 설정이 무시되고 agent 가 퍼블릭 엔드포인트로 접속을 시도하는데, prod DB 서브넷의 라우트 테이블(rtb-0d9a10a38c52ad9a6)에는 인터넷 경로가 없어서 SSM 이 오프라인 상태가 되고 start.sh 의 wait_for_ssm 이 타임아웃까지 매달릴 것 같습니다. 같은 서브넷에 같은 계열 AMI 로 떠 있는 prod DB EC2 가 현재 SSM 에 등록되어 있지 않은 것도 같은 이유로 보입니다.
이런 부분은 config_path 를 두 경로 모두로 두고 snap 디렉터리가 존재할 때만 그쪽에도 함께 기록하는 방향으로 해결 가능하다고 생각하는데, 해당 내용에 대해서 의견 부탁드립니다!

의견 주신 내용이 맞습니다. 기본 AMI가 Ubuntu 24.04 계열이라 snap 설치본일 가능성이 있고, 기존처럼 /etc/amazon/ssm/amazon-ssm-agent.json만 쓰면 snap agent가 endpoint 설정을 읽지 못할 수 있었습니다.
반영했습니다. user data에서 기본 경로 /etc/amazon/ssm/amazon-ssm-agent.json은 계속 쓰고, /var/snap/amazon-ssm-agent/current 디렉터리가 존재하면 snap 경로의 amazon-ssm-agent.json에도 같은 Ssm/Mgs/Mds endpoint 설정과 region을 기록하도록 수정했습니다. 그 후 기존 순서대로 snap service를 우선 재시작하므로, private DNS를 끈 interface endpoint 구성에서도 snap agent가 endpoint-specific DNS를 사용하게 됩니다.
