📌 Summary

운영·개발 서버에서 디스크를 계속 차지하던 컨테이너 로그·옛 앱 이미지·Prometheus 데이터에 자동 정리 한도를 두고, 디스크·앱 다운 Slack 알림을 추가합니다.

Closes WTH-21

Important

머지 전에 서버 환경 변수를 먼저 추가해 주세요

  • 파일: /home/ubuntu/infra/prod/.env.monitoring
  • 추가: SLACK_ALERT_WEBHOOK_URL=<알림 받을 Slack 채널의 Incoming Webhook URL>
  • 빠뜨려도 Grafana는 정상 기동하지만(자리표시 기본값) 알림이 나가지 않습니다.
  • 머지·배포 후 서버 작업은 아래 "서버 작업 체크리스트"를 참고해 주세요.

📝 Changes

What

  • prod·dev compose의 앱 외 모든 컨테이너에 Docker 로그 제한 적용 (json-file, 20MB × 3개)
    • prod: caddy, redis, alloy, loki, redis-exporter, prometheus, node-exporter, grafana
    • dev: caddy, mysql, redis, alloy, loki, grafana
    • 앱(blue/green)은 기존 제한 그대로 유지 (prod 100MB × 5, dev 50MB × 3)
  • deploy.sh(prod·dev): docker image prune -f → docker image prune -af --filter "until=168h"
  • prod Prometheus: --storage.tsdb.retention.time=15d, --storage.tsdb.retention.size=2GB
  • prod Grafana 알림 프로비저닝 추가 (grafana/provisioning/alerting/alerting.yaml) → Slack
    • 루트 디스크 사용률 80% 초과 5분 지속
    • app-blue/green 모두 수집 실패 2분 지속
    • 데이터가 끊겨도(NoData) 알림으로 처리 — 디스크가 꽉 차면 Prometheus가 먼저 멈추기 때문

Why

  • 2026-11-04 12:48 KST쯤 운영 EC2 루트 디스크(28GB)가 가득 차서 로그인이 실패했습니다. 앱 헬스체크는 DOWN(503)이 됐고, Loki·Prometheus는 no space left on device로 멈췄습니다. 디스크는 하루 약 0.2GB씩 꾸준히 줄고 있었습니다.
  • 앱 외 컨테이너의 Docker 로그에 크기 제한이 없었습니다.
  • 기존 docker image prune -f는 태그 없는 이미지만 지워서, 배포마다 받은 옛 앱 이미지가 계속 남았습니다.
  • Prometheus에 용량 제한이 없었습니다.

How

  • compose 상단에 x-default-logging 앵커를 두고, 각 서비스에서 logging: *default-logging으로 참조합니다.
  • Prometheus는 command를 지정하면 이미지 기본 인자를 대체하므로, --config.file과 --storage.tsdb.path도 함께 지정했습니다.
  • 7일 이내 이미지는 롤백용으로 남깁니다.
  • Slack 웹훅은 .env.monitoring의 SLACK_ALERT_WEBHOOK_URL로 받습니다. 비어 있으면 알림 프로비저닝 검증에 실패해 Grafana가 기동하지 않으므로, compose에서 자리표시 값을 기본으로 둡니다.

📸 Screenshots / Logs

  • docker compose config로 4개 compose 파일이 모두 정상 해석되고, 모든 서비스에 로그 제한이 붙는 것을 확인했습니다.
  • bash -n으로 deploy.sh 2개의 문법을 확인했습니다.
  • 로컬 Grafana 11.5.2에서 알림 규칙 2개·연락처·정책이 로드되는 것을 확인했습니다. 웹훅이 빈 값이면 기동 실패, 자리표시 값이면 정상 기동하는 것도 확인했습니다.

💡 Reviewer 참고사항

배포로 자동 반영되는 것은 deploy.sh와 앱(blue/green) 컨테이너뿐입니다. 나머지는 서버에서 직접 해야 합니다.

🖥️ 서버 작업 체크리스트 (prod EC2)

장애 복구 (11/4 완료)

  • 디스크 확보
  • 앱 헬스 UP, Redis 저장 정상, 로그인 정상 확인

한 번만 (이 PR과 무관)

  • EBS 증설 및 파일 시스템 확장 (28GB → 42.5GB, 11/4 15:47 반영 확인)
  • journald 크기 제한: /etc/systemd/journald.conf에 SystemMaxUse=200M → sudo systemctl restart systemd-journald

이 PR 머지·배포 전

  • /home/ubuntu/infra/prod/.env.monitoring에 SLACK_ALERT_WEBHOOK_URL=<알림 채널 웹훅> 추가 (없어도 Grafana는 뜨지만 알림이 나가지 않음)

이 PR 머지·배포 후

  • caddy·redis 로그 설정 반영 (/home/ubuntu/infra/prod에서): docker compose up -d caddy redis
    • 컨테이너 재생성. Redis 데이터는 볼륨에 유지, caddy 재생성 중 몇 초간 요청이 끊길 수 있으니 트래픽이 적은 시간에
    • 재생성하면 기존 대용량 json 로그도 함께 삭제됨
  • 모니터링 스택 반영: bash /home/ubuntu/infra/prod/monitoring/scripts/deploy.sh
    • docker compose up을 직접 실행하지 말 것 — 스크립트가 --env-file .env.monitoring과 DOCKER_GID를 넘겨야 Grafana 계정 등 환경 변수가 채워짐
  • 확인: docker inspect --format '{{.Name}} {{.HostConfig.LogConfig.Config}}' $(docker ps -q)에 모든 컨테이너 max-size 표시
  • 확인: Grafana → Alerting → Alert rules에 규칙 2개 표시. 파일 시스템 확장 전이면 디스크 규칙이 바로 울림(현재 85%)

dev 서버

  • 위 "머지·배포 후" 절차 동일하게 (docker compose up -d caddy mysql redis, 모니터링은 dev의 monitoring/scripts/deploy.sh). 알림은 prod에만 있음

✅ Checklist

  • PR 제목 설정 완료 (WTH-123 인증 필터 설정)
  • 테스트 구현 완료 (설정 변경, docker compose config로 검증)
  • 리뷰어 등록 완료
  • 자체 코드 리뷰 완료

🤖 Generated with Claude Code

Summary by CodeRabbit

  • 운영 개선
    • 개발 및 운영 환경의 주요 서비스 로그를 파일당 20MB, 최대 3개로 제한합니다.
    • 7일 넘게 사용하지 않은 Docker 이미지를 정리합니다.
    • 운영 모니터링에 디스크 사용량 및 앱 응답 상태 알림을 추가했습니다. 알림은 Slack으로 전송되며, 웹훅이 설정되지 않은 경우 자리표시 URL이 사용됩니다.

Walkthrough

개발 및 프로덕션 컨테이너의 로그 파일 제한을 설정했습니다. 프로덕션 Grafana에 Slack 알림 수신기와 디스크 및 앱 상태 규칙을 추가했습니다. 두 배포 스크립트에서 Docker 이미지 정리 기준을 168시간으로 변경했습니다.

Changes: 컨테이너 로그 제한

Layer / File(s) Summary
개발 및 프로덕션 로그 제한
infra/dev/docker-compose.yml, infra/dev/monitoring/docker-compose.yml, infra/prod/docker-compose.yml
개발 및 프로덕션 Docker Compose 설정에 json-file 로그 드라이버와 파일당 20m, 최대 파일 수 3을 지정했습니다. 해당 설정을 Caddy, MySQL, Redis 및 개발 모니터링 서비스에 적용했습니다.

프로덕션 모니터링

Layer / File(s) Summary
모니터링 서비스 및 Prometheus 설정
infra/prod/monitoring/docker-compose.yml
모니터링 서비스에 공통 로그 제한을 적용했습니다. Prometheus의 설정 파일과 저장소 경로를 명시하고, 보존 기간을 15일, 저장소 크기 제한을 2GB로 설정했습니다. Grafana의 Slack 웹훅 환경 변수를 추가했습니다.
Grafana 알림 및 규칙
infra/prod/monitoring/grafana/provisioning/alerting/alerting.yaml
Slack 수신기와 알림 그룹 정책을 추가했습니다. 루트 디스크 사용률이 5분간 80%를 초과하거나 weeth-app의 up 값 최댓값이 2분간 1 미만이면 알림 상태가 됩니다. 데이터 없음과 실행 오류도 알림 상태로 처리합니다.

배포 이미지 정리

Layer / File(s) Summary
이미지 정리 조건 변경
infra/dev/scripts/deploy.sh, infra/prod/scripts/deploy.sh
이미지 정리 명령을 docker image prune -af --filter "until=168h"로 변경했습니다.

Merge Risk: Moderate · up to 2235b

Validate the Slack webhook before merging: deployment can otherwise succeed without delivering disk or app alerts. Image cleanup also needs attention to preserve recently retired releases and avoid deployment failures under disk pressure. Smaller monitoring regressions remain.

토끼가 로그 크기를 살펴봐요
파일 셋, 크기는 이십 메가
디스크와 앱 상태도 확인해요
알림은 Slack으로 깡총
오래된 이미지는 정리하고
새벽에도 로그는 차곡차곡

Review comments at @infra/dev/monitoring/docker-compose.yml:
- Line 13: Alloy 재생성 후에도 로그 위치 정보가 유지되도록 Alloy 서비스의 위치 정보 저장 경로를 확인하고, 해당 경로를 영구
볼륨에 연결하세요. 기존 위치 정보가 새 볼륨으로 보존되며 Alloy가 재생성 후에도 그 볼륨을 사용하도록 설정하세요.

Review comments at @infra/dev/scripts/deploy.sh:
- Line 106: 배포 스크립트의 `docker image prune -af --filter "until=168h"` 정리 단계를 이미지
pull보다 앞에 배치하고, 디스크 여유 공간이 부족할 때 pull 전에 실행되도록 하세요. 기존의 이미지 정리 범위와 배포 동작은 유지하세요.

Review comments at @infra/prod/monitoring/docker-compose.yml:
- Around line 62-66: Prometheus의 command 인자에서 내장 콘솔 경로 설정이 빠져 있습니다. Prometheus
서비스의 command에 이미지의 콘솔 라이브러리와 템플릿 위치를 지정하는 인자를 추가해 `/consoles/node-cpu.html` 요청이
정상 처리되도록 하세요.
- Around line 108-109: SLACK_ALERT_WEBHOOK_URL 설정이 없을 때 자리표시 값으로 배포가 계속되지 않도록
하고, 배포 전에 웹훅 설정을 검증해 누락되면 명확한 오류와 함께 배포를 중단하세요.

Review comments at
@infra/prod/monitoring/grafana/provisioning/alerting/alerting.yaml:
- Around line 43-45: 경고 규칙의 B 표현식에서 exporter별 루트 디스크 사용률이 하나의 시계열만 남도록 중복을
제거하세요. `/`와 별도 `/rootfs` 마운트가 모두 루트로 표시되는 경우에도 exporter마다 경고 인스턴스가 하나만 생성되도록 하고,
기존 80% 임계값은 유지하세요.

Review comments at @infra/prod/scripts/deploy.sh:
- Line 106: 배포 스크립트의 docker image prune 명령은 이미지 생성 시각을 기준으로 삭제하므로, 이전 릴리스의 사용 종료
후 7일간 보존되도록 변경해 주세요. 운영과 개발 스크립트 모두에서 사용 종료 시각을 추적해 보존 기간을 판단하고, 그 시각이 7일을 넘긴
이미지에만 삭제가 적용되도록 하세요.

Alloy의 로그 위치 정보를 재생성 전에 보존하세요.

이번 설정을 적용하면 Alloy가 재생성되고 위치 정보가 사라집니다. 그러면 Alloy가 남아 있는 앱 로그를 다시 전송할 수 있습니다. Loki는 일부 로그를 중복 저장할 수 있습니다. 기존 위치 정보를 영구 볼륨으로 옮기고 Alloy가 해당 볼륨을 사용하도록 설정하세요.

경고 규칙의 B 표현식에서 exporter별 루트 디스크 사용률이 하나의 시계열만 남도록 중복을 제거하세요. `/`와 별도 `/rootfs`
마운트가 모두 루트로 표시되는 경우에도 exporter마다 경고 인스턴스가 하나만 생성되도록 하고, 기존 80% 임계값은 유지하세요.

이전 이미지의 사용 종료 시각을 기준으로 보존해 주세요.

7일 넘게 실행한 릴리스를 교체하면 이전 이미지가 즉시 삭제될 수 있습니다. until은 사용 종료 시각이 아니라 생성 시각을 기준으로 합니다. 운영과 개발 스크립트에서 이전 이미지의 사용 종료 후 7일이 지날 때까지 삭제를 막아 주세요.

Review comment at @infra/prod/scripts/deploy.sh at line 106:
배포 스크립트의 docker image prune 명령은 이미지 생성 시각을 기준으로 삭제하므로, 이전 릴리스의 사용 종료 후 7일간 보존되도록
변경해 주세요. 운영과 개발 스크립트 모두에서 사용 종료 시각을 추적해 보존 기간을 판단하고, 그 시각이 7일을 넘긴 이미지에만 삭제가
적용되도록 하세요.
