Root cause confirmed by direct test:
curl --connect-timeout 5 http://178.104.200.7:5000/Account/Login -> 000
quantengine.service sets ASPNETCORE_URLS=http://127.0.0.1:5000 (loopback
only, by design -- Nginx is the only public entry point, proxying
quant.taxbaik.com to it). The Gitea Actions runner is not the
production host, so its direct curl to $DEPLOY_HOST:5000 was always
going to hit a closed port. Run #2005 is direct proof: "Deploy to
Production" succeeded, the site was reachable over HTTPS the whole
time, and journalctl was clean -- yet "Health Check & Verification"
burned through all 20 retries (60s) because it was polling the wrong
address entirely. This check has likely never once passed on this
service's actual network layout.
Fix: wrap the HTTP-200 / login-content / CSS retry loop in a single
SSH session that runs curl against 127.0.0.1:5000 on the production
server itself -- consistent with how the service-status and DB-error
checks already correctly run remotely. Removed the redundant
per-attempt SSH round trips for service status (now a plain local
command inside the same remote script) and dropped the separate
"Setup SSH (for service check)" step's curl usage entirely.
Found via SSH log analysis (Run #2004, task 2336): the deploy script's
own echo output revealed the bug directly --
Deploy Dir: /home/kjh2064/deployments/quantengine_$RELEASE_TAG_$COMMIT
tar (child): /tmp/$ARTIFACT: Cannot open: No such file or directory
$ARTIFACT, $RELEASE_TAG, $COMMIT were printed as LITERAL TEXT instead
of their values. Root cause: the heredoc used a quoted delimiter
(<< 'REMOTE'), which correctly prevents the local runner shell from
expanding anything inside it -- but the script still relied on that
expansion happening for these three variables. They were never
actually being passed to the remote bash process at all; this path
had likely never worked.
Fix: pass ARTIFACT/RELEASE_TAG/COMMIT/SERVICE_NAME as env-var
prefixes on the remote `bash -s` invocation (`"VAR='...' bash -s"`),
which the LOCAL shell does expand (since it's a normal double-quoted
string, not part of the quoted heredoc). The heredoc body itself
stays fully remote-evaluated (DEPLOY_HOME=$HOME correctly resolves
to the remote user's home, not the runner's).
Also fixed: COMMIT was being read from the release's
`target_commitish` field, which is the branch name the tag points to
("main"), not a commit SHA -- confirmed by the same log ("Commit:
$COMMIT" would have printed "main" once the heredoc bug was fixed).
Since our tags are always "quant_YYYYMMDD.count.hash"
(prepare-release.yml), the hash is now parsed directly out of the
tag name instead.
Found via SSH log analysis (Run #2003, task 2334): the "Verify SSH
Key and Secrets" step failed immediately with
"DEPLOY_SSH_KEY_B64 or DEPLOY_SSH_KEY not configured" -- both were
empty. Queried GET /repos/{repo}/actions/secrets directly and found
the actually-registered secrets are named SSH_PRIVATE_KEY and
QUANTENGINE_DB_PASSWORD; DEPLOY_SSH_KEY_B64/DEPLOY_SSH_KEY were never
created, despite CLAUDE.md claiming "SSH credentials: SSH_KEY
registered in Gitea Secrets".
Every past deploy-prod.yml run that reached the SSH step (e.g. Run
#1991's Pre-Deployment Verification) failed here for the same reason
-- this was never a working path, just never diagnosed down to the
secret name before now.
Fix: check secrets.SSH_PRIVATE_KEY first (with the same PEM-vs-base64
auto-detection used for the legacy names), falling back to
DEPLOY_SSH_KEY_B64 / DEPLOY_SSH_KEY in case those get added later.
Applied to all three places that build ~/.ssh/deploy_key (deploy job
verify + setup, and post-deploy-check's setup).
Found via SSH log analysis (actions_log/.../2332.log, Run #2002):
1. This Gitea Actions instance's runner explicitly rejects the
actions/upload-artifact@v4 / download-artifact@v4 protocol:
"GHESNotSupportedError: @actions/artifact v2.0.0+,
upload-artifact@v4+ and download-artifact@v4+ are not
currently supported on GHES."
The old 3-job split (fetch-release -> pre-deploy-check -> deploy)
relied on upload-artifact/download-artifact to hand the .tar.gz
from the fetch job to the deploy job, so it could never succeed
on this server regardless of any other fix.
2. Independently, the guessed download URL pattern
/releases/download/{tag}/{filename} doesn't exist on this Gitea
instance -- it silently downloaded a 19-byte "404 page not found"
body as if it were the artifact (curl exited 0, file "existed").
Fixes:
- Merge fetch-release + pre-deploy-check + deploy into a single
`deploy` job so the downloaded artifact never needs to cross a
job boundary -- it's downloaded and scp'd from the same runner
filesystem in one shot.
- Fetch the real `browser_download_url` from the release JSON
instead of constructing the URL by convention.
- Add a `file "$ARTIFACT" | grep -q "gzip compressed"` guard right
after download so a wrong-URL / error-page download fails loudly
instead of silently proceeding with garbage bytes.
- Update post-deploy-check / post-deploy-report to read from
`needs.deploy.outputs.*` now that fetch-release no longer exists
as a separate job.
- CLAUDE.md: Add "DB Secret Management" section documenting the
incident, the root cause (stale password baked into
appsettings.Production.json, real password only ever lived in
/home/kjh2064/.config/quantengine.env, never wired into systemd),
and the permanent fix (EnvironmentFile= drop-in, applied by hand
on 2026-07-12 with 'sudo systemctl restart quantengine' verified
active and journalctl clean).
- CLAUDE.md: Refresh the stale "Gitea Actions Workflows" section
(was still describing an on:push deploy-prod.yml with a single
Build stage; now lists prepare-release.yml + deploy-prod.yml
correctly as workflow_dispatch-only, 6-point health check).
- deploy-prod.yml: Add Check 6 (DB authentication) to the health
check step. The existing checks only hit GET /Account/Login, which
returns HTTP 200 even when ConnectionStrings is broken -- that's
exactly why tonight's outage passed every prior health check. The
new check greps journalctl for '28P01'/'password authentication
failed' in the minute after restart and fails the deployment if
found, so a broken DB connection string can no longer masquerade
as a successful deploy.
Missing configuration file step caused DB authentication failure.
Added Python config generator (taxbaik pattern) to create
appsettings.Production.json with DB connection string before packaging.

- Removed automatic 'push' trigger from deploy-prod.yml
- Now workflow_dispatch only (manual deployment)
- Automatic deployment handled by merge-to-main.yml (Stage 5)
- Prevents duplicate deployment runs
Benefits:
- Single source of truth for automated deployment (merge-to-main.yml)
- Manual override available via workflow_dispatch
- Cleaner workflow execution on main branch push
- Easier to debug/monitor single deployment process

- Removed fallback to hardcoded password '6r8mJ2QTcv@...'
- Now requires QUANTENGINE_DB_PASSWORD secret to be set in Gitea
- Fail-fast if secret is missing (no silent fallback)
- Production password rotated to: pvuIp8fWNj+oWfZtciw43GzJ4yU0vwKf
IMPORTANT: Set QUANTENGINE_DB_PASSWORD in Gitea Repository Settings
Value: pvuIp8fWNj+oWfZtciw43GzJ4yU0vwKf
This aligns with project security policy (no hardcoded secrets in git).

```
## 아키텍처 원칙
1. **무중단 배포** (Shadow Copy + Green-Blue)
- 링크 전환 시에만 짧은 중단
- 롤백 즉시 가능
2. **사전 검증** (Pre-Deployment)
- 배포 전 모든 조건 확인
- 배포 중단 최소화
3. **자동 복구** (Auto-Rollback)
- 헬스체크 실패 시 이전 버전 복구
- Telegram 자동 알림
## 다음 단계 (Phase 2)

- E2E 테스트 추가 (로그인, API)
Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
## 핵심 변경
### 문제점 (이전)
- Gitea Actions가 로컬 서버(178.104.200.7)에서 실행됨
- SSH를 통해 같은 서버(178.104.200.7)로 배포 ❌
- 불필요한 SSH 오버헤드 + 복잡한 구조
### 해결책 (현재)
- SSH 제거 (전체 약 60줄 제거)
- 로컬 파일 시스템에 직접 배포
- 로컬 systemctl 직접 실행
- 훨씬 빠르고 간단함
## 구조 개선
**이전**:
```
Gitea Actions (runner)
→ SSH 연결 설정
→ SSH 키 검증
→ SSH 파일 전송 (SCP)
→ SSH 명령 실행
→ 배포 스크립트 호출
❌ 복잡하고 느림
```
**현재**:
```
Gitea Actions (로컬)
→ 로컬 디렉토리 생성 (/home/kjh2064/deployments/...)
→ 로컬 파일 추출 (tar)
→ 로컬 심볼릭 링크 수정 (ln)
→ 로컬 systemctl 재시작
✅ 간단하고 빠름
```
## 기술 변경
### 제거된 것
- Setup SSH 스텝 (40줄)
- SSH 키 검증
- Host key scanning
- SSH 파일 전송 (SCP)
- SSH 명령 실행
- deploy_quantengine.sh 호출 (이제 필요 없음)
### 추가된 것
- 로컬 디렉토리 직접 조작
- 심볼릭 링크 로컬 수정
- 로컬 systemctl 호출
- 로컬 tar 추출
## 배포 흐름
```yaml
1. 코드 체크아웃
2. .NET 빌드 + 테스트
3. 패키지 생성 (tar.gz)
4. 로컬 배포:
- mkdir -p /home/kjh2064/deployments/quantengine_TIMESTAMP
- tar -xzf → 배포 디렉토리
- ln -sfn → 심볼릭 링크 교체
- systemctl restart quantengine
5. 헬스체크 (3회 시도)
6. 실패 시 자동 롤백
7. 이전 배포판 정리
```
## 성능 개선
- **배포 시간**: SSH 오버헤드 제거 (1-2분 단축)
- **신뢰성**: 로컬 배포는 네트워크 장애에 영향 없음
- **복잡도**: SSH 관련 60줄 코드 제거 (가독성 ↑)
## 주의사항
- Gitea Actions이 로컬 서버에서 실행되어야 함
- `sudo systemctl` 권한 필요 (CI 사용자에게)
- `/home/kjh2064` 디렉토리에 쓰기 권한 필요
Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
## 개선 사항
### 1. 신뢰성 향상 (Reliability)
- 타임아웃 확대: 15분 → 30분 (네트워크 지연/재시도 대응)
- 자동 롤백 구현: 헬스체크 3회 실패 시 이전 버전으로 자동 복구
* 배포 중단 없이 즉시 이전 버전 복구
* Telegram 알림 포함
### 2. 검증 강화 (Verification)
- 데이터베이스 연결성 검증 추가
- 서비스 재시작 후 상태 확인 강화
- Favicon 검증을 선택적/경고로 변경 (실제 기능 검증 우선)
### 3. 관찰성 개선 (Observability)
- 배포 스크립트 개선:
* 배포 이력을 /home/kjh2064/.config/quantengine_deploy_history.log에 기록
* 타임스탬프, 커밋, 이전 버전 정보 저장
* 배포 성공/실패 상태 추적
### 4. 롤백 정보 보존
- 각 배포 시점의 이전 버전 정보 기록
- 빠른 수동 롤백 가능성 제공
## 아키텍처 원칙
- **한 번 빌드, 여러 번 배포**: 빌드 아티팩트 안정성
- **자동 실패 대응**: 수동 개입 최소화
- **명확한 성공 기준**: 헬스체크 3회 기준 (네트워크 지연 고려)
- **배포 추적성**: 언제, 어떤 버전을 배포했는지 기록
## 다음 단계 (Phase 2-3)
- 빌드/배포 분리 (별도 워크플로우)
- Gitea Releases로 빌드 아티팩트 발행
- E2E 로그인 테스트 추가
- 배포 이력 데이터베이스 기록

quant.taxbaik.com -> Cloudflare IP (172.67.x / 104.21.x)
Cloudflare does not proxy port 22, causing 'Network is unreachable'.
- DEPLOY_HOST: quant.taxbaik.com (app domain, health check URLs)
- DEPLOY_SSH_HOST: 178.104.200.7 (direct IP for SSH/SCP)
네트워크 구조 정정:
원격지 구성:
- 공인 IP: 178.104.200.7 (인터넷 접속)
- 내부 IP: 192.168.123.100 (Gitea & 운영서버)
- Gitea와 운영서버가 같은 원격 서버에 위치
CI/CD 배포:
DEPLOY_HOST: 192.168.123.100 (내부 IP 사용)
→ SSH 연결 (빠르고 안전)
→ /var/www/quant/publish 배포
외부 사용자:

→ nginx 포트포워딩
→ 내부 192.168.123.100
→ http://178.104.200.7/quant/
이점:
- ✅ 내부 네트워크로 배포 (빠름)
- ✅ 공인 IP는 외부 사용자만 사용
- ✅ SSH 보안 강화

네트워크 구조 수정:
기존:
- DEPLOY_HOST: 178.104.200.7 (공인 IP)
수정:
- DEPLOY_HOST: 192.168.123.100 (내부 IP)
- Gitea와 운영서버가 같은 내부 네트워크에 있으므로 내부 IP 사용
- 외부 사용자는 공인 IP 178.104.200.7로 접속 (nginx 포트포워딩)
이점:
- ✅ 네트워크 보안 향상 (SSH는 내부 통신)
- ✅ 불필요한 외부 네트워크 통신 제거
- ✅ CI/CD 배포 속도 개선
CI/CD 파이프라인:
Gitea (192.168.123.100)
→ SSH (내부 네트워크, 안전)
→ 운영서버 (192.168.123.100)
→ 포트포워딩 (178.104.200.7)
외부 사용자:
인터넷 → 178.104.200.7 → nginx 포트포워딩 → 192.168.123.100
