Description

PR #3802(main → release)의 병합 충돌을 해결하기 위해 release를 main 기반 브랜치에 병합했습니다.
admin-api와 client-api의 kustomization.yaml에서 충돌한 HTTPRoute 파일 참조를 실제 파일명인 httproute.yaml로 통일했습니다.

Additional Context

  • release의 기존 커밋 이력이 포함되어 커밋 수가 많지만, 실제 main 대비 변경은 4개 파일입니다.
  • admin-api/client-api의 stage·production 구성 4개 모두 Kustomize 빌드를 통과했습니다.
  • 충돌 해결 이력을 보존하도록 Create a merge commit 방식으로 병합해주세요.

Before submitting the PR, please make sure you do the following

Summary by CodeRabbit

  • Infrastructure
    • Updated admin API routing configuration for the production and staging environments. Both continue to route /graphql and /admin-api requests to the admin API.
  • Documentation
    • Added guidance for checking installed n8n settings before upgrades, including warnings about storage and ingress configuration differences that could prevent the replacement service from starting.

### Description

이전 #3140 에서 release 브랜치에 squash commit을 만들면서, main 브랜치와 release의
merge-base가 가장 마지막 커밋이 아니라, main 브랜치와 release 브랜치가 분기된 최초의 커밋이 되었습니다.

아래 그림으로 조금 더 자세히 설명하면, release branch는 main branch로부터 커밋 `e63a60f5`에서
분기되었고, 이후 9월 1일에 release PR을 통해 main branch의 `f024ba37`까지의 변경 내용이
release branch로 squash merge되었습니다. 하지만 merge commit이 아니라 새로운 squash
commit을 생성하였기 때문에, merge-base는 `f024ba37`가 아니라 그대로 `e63a60f5`로 남아있습니다.

즉, 지금 새로운 release PR을 만든다면 GitHub의 diff는 `f024ba37`를 base로 하는 것이 아니라
`e63a60f5`를 base로 하게되고, 그러면 `e63a60f5` 이후 두 브랜치에서 발생한 모든 수정 내역에 대해 merge
conflict가 발생합니다.

예를 들어 9월 1일 release 전에 파일 A에 수정 x를 했고 release 이후에 같은 파일 A에 수정 y를 했다고
합니다. 새로운 release PR을 만들면 git은 release 브랜치에는 수정 x가, main 브랜치에는 수정
x+y(=z)가 되어있는 것으로 여기게 되고 merge conflict로 간주합니다.

이 같은 문제를 방지하려면 `f024ba37`가 merge base가 되도록 merge commit을 생성해야합니다. merge
commit을 생성하면 release branch의 base도 기존의 `e63a60f5`에서 새로운 `f024ba37`로
변경됩니다. 따라서 앞으로는 release 브랜치에 squash and commit을 사용하지 않도록 합니다.

아마 현재 사용 중인 `db.t4g.small` 클래스의 RDS 인스턴스의 실제 사용 가능한 커넥션 수가 약 180개로
추정됩니다.

5가 아니라 3으로 줄이고 대신 vCPU 제한을 증가시시킵니다.
또한, 과도한 커넥션 생성 방지를 위해 DATABASE_URL에 `connection_limit=20`을 추가합니다.

Set query_ready_num_days to 90 (matching retention period) so the TSDB
index shipper downloads index tables from S3 at startup. Without this,
loki only serves logs from the ingester's 3-hour window — all historical
data is unreachable because the on-demand index loading path does not
work correctly in SingleBinary mode with loki 3.6.5.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
## Summary
- Loki 3.6.5의 TSDB index shipper가 S3에서 인덱스 테이블을 사전 로드하지 않아, ingester 메모리
범위(3시간) 밖의 모든 과거 로그 쿼리가 불가능했던 문제 수정
- `query_ready_num_days: 90` 설정 추가 (retention_period 2160h = 90일과 일치)
- 시작 시 S3에서 90일치 인덱스 테이블을 다운로드하여 과거 데이터 쿼리 활성화

## Root Cause
- `query_ready_num_days: 0` (기본값)으로 인해 `ensureQueryReadiness()`가 S3 테이블
목록 조회 없이 즉시 반환
- SingleBinary 모드에서 온디맨드 인덱스 로딩 경로가 정상 동작하지 않아, 사전 로딩이 필수

## Test plan
- [ ] ArgoCD loki-production sync 확인
- [ ] loki 시작 로그에서 `"index pre-download for query readiness completed"`
메시지 확인
- [ ] Grafana에서 과거 날짜(예: 2025-12-01) 로그 쿼리 동작 확인
- [ ] 마이그레이션된 구 minio 데이터(~3개월치) 쿼리 가능 여부 확인

### Description

Promotes the authenticated Iris pprof routing from main to production.

This replaces the unauthenticated direct Service route with BasicAuth,
request limits, and kube-apiserver pods/proxy routing. The required
production iris-pprof-client certificate has been provisioned before
promotion.

### Production validation

- Unauthenticated stage /pods returns 401.
- The old stage /debug/pprof route returns 404.
- Production is temporarily protected by emergency-deny-iris-pprof until
this rollout is healthy.
- RabbitMQ test/rejudge topology was repaired separately and both
workers are healthy.
### Description

Iris `ServersTransport`가 참조하는 `iris-pprof-client` TLS Secret이 매니페스트에 없어
stage에서 Traefik → kube-apiserver mTLS가 실패합니다. production에는 제가 수동으로 TLS
secret을 적어두었으나, 장기적으로 각 클러스터 CA로 서명한 `CN=iris-pprof` 클라이언트 인증서를
SealedSecret으로 추가하고 stage·production Iris overlay에 연결해야 합니다.

Continuation of #3757,
#3760

### Additional context

- 인증서는 `kubernetes.io/kube-apiserver-client` CSR로 발급한 뒤 각 클러스터 sealing
키로 봉인했습니다.
- 이 인증서 교체는 Traefik → kube-apiserver 인증에만 영향을 주며 pprof basicAuth 자격증명은
바뀌지 않습니다.
  - 즉, pprof API를 사용하는 사용자들에게는 영향을 미치지 않습니다.
- 검증: 두 overlay `kustomize build` 통과,
`pprof.codedang.com`·`pprof.stage.codedang.com`의 `/pods`와
`/pod/<pod>/debug/pprof/goroutine` 200 응답.

## Description

문제 삭제 시 본문에 포함된 이미지 및 첨부 파일을 함께 삭제하는 로직을 비활성화합니다.

현재 문제 본문을 복사하여 새로운 문제를 생성할 경우, 첨부 파일이 새로 생성되지 않고 기존 파일 URL을 그대로 참조합니다.
이 상태에서 둘 중 하나의 문제를 삭제하면 공유 중인 파일이 삭제되어, 남아 있는 문제에서 첨부 파일이 깨지는 문제가 발생합니다.

production에서의 데이터 손실을 방지하기 위해 hotfix로 첨부 파일 삭제 로직을 우선 비활성화합니다.

## Changes

- 문제 삭제 시 본문의 이미지 및 첨부 파일을 DB와 S3에서 삭제하는 로직 비활성화

<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit

- **Behavior Changes**
- Deleting a problem no longer removes its associated attachments from
storage or the file records.
- Deleting an individual attachment now leaves the attachment unchanged
after ownership validation.
- Problem deletion still removes the problem itself and enforces
ownership permissions.

### Description

- Return a compile error when the compiler exits with a nonzero status,
while keeping compiler startup failures as server errors.
- Preserve compiler diagnostics in the judge response.
- Remove a status-code comparison that incorrectly treated compile
errors as system errors.

### Additional context

A failed compilation now returns `resultCode: 6` with the compiler
diagnostic instead of `resultCode: 9` and a missing `log.out` error.

Tests passed: `go test ./src/service/sandbox/judger ./src/service/build

### Description

백엔드(client·admin)의 HTTP 요청 처리 시간 메트릭(`http.server.duration`)이 실제보다
**2배**로 집계되던 문제를 고칩니다.

요청 하나가 들어오면 두 곳에서 각각 기록하고 있었습니다.

- `nestjs-otel`의 `apiMetrics` 기능
- OpenTelemetry의 표준 HTTP 계측 (`@opentelemetry/instrumentation-http`)

두 곳이 **같은 이름**으로 기록해서, 대시보드에서 합치면 숫자가 두 배가 됩니다.
`apiMetrics`는 그대로 켜 두고, `nestjs-otel`이 만든 `http.server.duration` 하나만
버리도록 설정했습니다(OpenTelemetry의 View 기능).

`apiMetrics`의 나머지 메트릭(요청·응답 크기, 요청 수 등)은 이름이 겹치지 않아 그대로 수집됩니다.

**로컬 확인** (로컬 관측성 스택, client에 요청 16번)

| 메트릭 | 수정 전 | 수정 후 |
|---|---|---|
| `http_server_duration` | 32 (두 곳에서 16 + 16) | 16
(`instrumentation-http` 한 곳) |
| `http_server_request_size`, `http_server_response_size` 등
`nestjs-otel` 메트릭 | 16 | 16 (그대로) |

### Additional context

처음에는 `apiMetrics`를 통째로 끄려 했지만, 그러면 요청·응답 크기처럼 다른 곳에서는 얻을 수 없는 메트릭까지 사라져서
겹치는 하나만 버리는 방식으로 바꿨습니다.

Closes TAS-3017

### Description

공개 `/api/internal` 및 하위 경로를 API backend로 전달하지 않도록 Gateway API
`HTTPRoute`를 추가합니다. backendRefs와 응답 필터가 없는 규칙으로 프록시에서 요청을 종료하며, 기존
Traefik 전용 `IngressRoute`·`noop@internal`·명시적 priority는 제거했습니다.
ClusterIP 직접 수집은 그대로 허용합니다.

### Additional context

- TAS-3004 stack의 첫 번째 PR이며 가장 먼저 병합·적용합니다.
- 병합 순서: 이 PR → [backend
#3770](#3770) → [Prometheus 수집
#3771](#3771). 다음 PR의 base는 부모
병합 후 main으로 변경합니다.
- `main-gateway`의 HTTP와 모든 HTTPS listener에 연결합니다. HTTPS listener의
namespace 허용 목록에 `kube-system`을 추가합니다. hostnames는 제한하지 않아 각 listener가
수용하는 모든 Host에 적용됩니다.
- `PathPrefix`로 `/api/internal`을 차단하고 `RegularExpression:
(?i)^/api/internal(/|$)`로 Express의 대소문자 우회를 막습니다.
`/api/internal-example`은 차단하지 않습니다.
- 정규식 지원과 정규식 경로의 우선순위는 Gateway API의 implementation-specific 기능입니다. 프록시
교체 시 해당 지원과 우회 차단을 다시 검증해야 합니다.
- 응답 코드는 기존 418에서 backend 없는 라우트의 5xx로 변경됩니다. [Gateway API
표준](https://gateway-api.sigs.k8s.io/reference/api-types/httproute/#backendrefs-optional)은
500을 정의하며, [Traefik의 빈 weighted
service](https://github.com/traefik/traefik/blob/v3.5/pkg/server/service/loadbalancer/wrr/wrr.go)는
503을 반환합니다.
- 실제 배포는 수행하지 않았습니다. HTTPRoute의 각 listener
`Accepted=True`·`ResolvedRefs=True`, 외부 경로 및 대소문자 변형의 차단, 기존 API 정상 동작을
확인한 뒤 backend를 적용합니다.

### Validation

- internal의 stage/production Kustomize 렌더링 통과.
- 두 환경에서 HTTPRoute가 6개 listener에 연결 가능하며 backend·필터·Traefik 확장 참조가 없는 것을
검증.
- 대소문자 변형·경로 경계 회귀 검사 통과: `PYTHONDONTWRITEBYTECODE=1 python3 -m unittest
discover -s infra/k8s/internal/tests -v`.
- 변경 YAML Prettier, git diff --check, commit hooks 통과.
### Description

admin과 client가 기존 PrismaService의 `$metrics.prometheus()` 결과를 반환하는
metrics endpoint를 제공합니다. admin과 stage/production client는
`/api/internal/prisma`, 개발 client는 기존 접두사 규칙에 따라 `/internal/prisma`를
사용합니다.

metrics는 JWT/admin 인증 없이 수집하고 Swagger에서는 숨깁니다. AdminGuard가 인증 제외 메타데이터를
user 참조보다 먼저 확인하도록 수정해 익명 요청의 오류를 방지합니다. 기존 보호 API의 JWT·admin 권한 검사는
유지합니다.

### Additional context

- TAS-3004 stack의 두 번째 PR입니다. [접근 차단 PR
#3769](https://github.com/skkuding/codedang/pull/3769)을 **먼저 병합·적용**하고
외부 차단을 확인한 뒤 이 PR을 병합합니다.
- 접근 차단 커밋의 amend에 맞춰 rebase했으며 backend 내용은 변경하지 않았습니다.
- 병합 순서: 접근 차단 → backend → 세 번째 [Prometheus 수집 PR
#3771](#3771).
- 접근 차단 squash merge 후 이 브랜치를 main으로 rebase하고 PR base를 main으로 변경합니다.
- 기존 Prisma 6.13.0에 metrics preview flag를 추가합니다. DB migration은 없습니다.
- 새 모듈은 @libs/internal 별칭으로 참조합니다. devcontainer lock 파일은 포함하지 않습니다.
- 실제 클러스터 배포는 수행하지 않았습니다.

### Validation

- HTTP 테스트 14개 통과: 익명 수집·Content-Type, JWT 보호, admin 일반 사용자 403, Swagger
제외, API 접두사 중복 방지.
- 본 폴더 소스의 tsc --noEmit 및 변경 TypeScript ESLint/Prettier 통과.
- 최종 소스를 임시 검증 환경에 복사해 정상 macOS 의존성으로 admin/client build 및 HTTP 테스트 통과.
- rebase 전후 backend 내용 동일 확인.


### Review updates

Removed the custom @libs/auth/* wildcard alias; the test-only
JwtStrategy import uses a relative source path. The @libs/auth and
@libs/internal public barrel aliases remain. HTTP tests (14), typecheck
and lint pass.

## Summary by CodeRabbit

- **New Features**
  - Added a Prometheus metrics endpoint for Prisma database monitoring.
- Metrics are available in client and admin environments with
appropriate authentication and administrator access controls.
- Internal metrics endpoints are excluded from generated API
documentation.

- **Bug Fixes**
- Improved authorization handling for routes that do not require
administrator access, avoiding unnecessary request and role processing.

<!-- end of auto-generated comment: release notes by coderabbit.ai -->
admin·client의 Prisma metrics를 기존 Prometheus에서 수집하도록 API별 ServiceMonitor를
추가합니다. Service label과 named http 포트로 대상 endpoint를 선택하여
`/api/internal/prisma`를 30초 간격으로 Pod별 직접 수집합니다.

기존 Prometheus의 release: prometheus selector, Grafana datasource 및 OTel
pipeline을 유지합니다. README에 내부 수집과 배포 후 확인 절차를 추가합니다.

- TAS-3004 stack의 **세 번째 PR**입니다. [접근 차단
병합·적용합니다.
- 기존 infra PR에서 ServiceMonitor, API Service label/port, API
Kustomization 등록, 수집 문서를 분리했습니다. 공개 접근 차단 리소스와 backend 코드는 포함하지 않습니다.
- backend squash merge 후 이 브랜치를 main으로 rebase하고 PR base를 main으로 변경합니다.
- API endpoint가 배포된 후 ServiceMonitor를 적용하고 모든 API Pod target UP과 Grafana
Explore의 prisma_pool_connections_busy 조회를 확인합니다.
- 실제 클러스터 배포는 수행하지 않았습니다. devcontainer lock 파일은 포함하지 않습니다.

- admin-api/client-api의 stage/production Kustomize 렌더링 통과.
- kube-prometheus-stack 79.5.0 Helm 렌더링으로 기존 ServiceMonitor selector 확인.
- ServiceMonitor label·namespace·named port 연결 및 수집 경로 검증 통과.
- YAML Prettier 및 commitlint hooks 통과.
- 분리 전후 Service/ServiceMonitor 설정 동일 확인. README의 테스트 명령 경로를 정정했습니다.

Rebased onto the reviewed parents. Collection configuration is
unchanged; README now documents the Gateway API HTTPRoute block,
listener attachment checks, case-insensitive matching,
implementation-specific regexp support, and the blocking 5xx response.

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->

- **New Features**
  - Added Prometheus metrics endpoints for the Admin and Client APIs.
  - Added automatic monitoring of API metrics every 30 seconds.
- API services now provide consistent discovery labels and named HTTP
ports.

- **Bug Fixes**
- Protected internal API routes from external forwarding while allowing
monitoring through internal service endpoints.

- **Documentation**
- Added guidance for configuring, validating, and querying API metrics
in Prometheus and Grafana.

Provision a Pyroscope data source in both stage and production Grafana
instances using the self-hosted Pyroscope service from the preceding
PRs.

- Add a non-editable `grafana-pyroscope-datasource` with stable UID
`pyroscope` and proxy access to
`http://pyroscope.monitoring-pyroscope.svc.cluster.local:4040`.
- Set `minStep` to `1m` to match Alloy's 60-second scrape interval.
- Keep all existing data sources intact.

**Stacked on #3788** (`t3042-configure-alloy`), which in turn depends on

- Confirmed the pinned Grafana chart 10.5.13 runs Grafana 12.3.1, which
supports the Pyroscope data source.
- `helm lint` and `helm template` passed with all three existing Grafana
values files for each environment.
- Parsed the rendered provisioning ConfigMap: exactly one Pyroscope data
source in each environment; existing data sources remain.
- YAML Prettier check and `git diff --check` passed.

The data source connection and profile queries require runtime
validation after deployment.
Install a self-hosted Pyroscope v2 backend in the existing monitoring
stack.

- Add an Argo CD ApplicationSet for stage (`main`) and production
(`release`) using Pyroscope Helm chart 2.3.1.
- Store profile blocks in the existing monitoring MinIO tenant and
persist metastore Raft state on a 10Gi PVC.
- Create the `pyroscope` bucket for new tenants and initialize it
idempotently for existing tenants.
- Reflect the existing MinIO user Secret into the Pyroscope namespace.
- Set profile retention and query lookback to 14 days in stage and 30
days in production.

Alloy collection and the Grafana data source are follow-up work.

- `helm lint` and `helm template` passed with both stage and production
values.
- Rendered settings were checked for retention, MinIO storage, bucket
initialization, and PVC.
- `kubectl kustomize` passed for both MinIO overlays.
- Prettier YAML check and `git diff --check` passed.

Cluster runtime validation remains for deployment after merge.

<!-- This is an auto-generated comment: release notes by coderabbit.ai

production.
* Added persistent storage for Pyroscope metadata and automatic
initialization of the profiling storage bucket.
  * Made monitoring credentials available to the Pyroscope environment.

* **Documentation**
* Added operational documentation covering deployment, storage,
retention, verification, and service connectivity.

Deploy Grafana Alloy to collect Iris pprof profiles and send them to the
self-hosted Pyroscope service.

- Deploy one Alloy instance per cluster through an Argo CD
ApplicationSet, using chart 1.12.1.
- Discover ready `iris`, `iris-test`, and `iris-rejudge` Pods in the
`iris` namespace and scrape each Pod IP on port 6060.
- Collect 10 seconds of CPU profiles every 60 seconds, alongside memory
and goroutine profiles; disable block and mutex profiles because Iris
does not enable their Go profiling rates.
- Restrict Kubernetes discovery RBAC to Pods in the `iris` namespace,
add environment labels, and expose Alloy metrics to Prometheus.

**Stacked on #3787** (`t3041-install-pyroscope`). Please review only the
Alloy commit in this PR. Grafana data source provisioning remains a
follow-up.

- `helm lint` and `helm template` passed for stage and production.
- The rendered River configurations passed `alloy validate` using Alloy
v1.19.2.
- Rendered RBAC contains only a namespaced Pod Role; rendered
deployments and environment labels were checked.
- `kubectl kustomize` confirmed all three Iris workloads are
discoverable in both clusters.
- YAML Prettier check and `git diff --check` passed.

Cluster runtime validation remains for deployment after merge.

<!-- This is an auto-generated comment: release notes by coderabbit.ai

* **New Features**
* Added Grafana Alloy monitoring deployment for stage and production
clusters.
* Alloy now discovers ready Iris pods, collects profiling data, and
forwards it to Pyroscope.
  * Added Prometheus health metrics through a ServiceMonitor.
  * Added environment-specific configuration for stage and production.

* **Documentation**
* Added deployment details and post-rollout verification steps for Alloy
monitoring.

Suggested reviewers: manamana32321

Merge Risk: ⚪ Minimal · up to c8da6

The change fixes the admin API route structure and adds upgrade guidance for n8n. No merge-blocking issue was found.

Security Architecture Review

Security architecture risk: 🔵 Low · up to c8da6

No new access, privilege, or routing expansion was established. The added warning addresses an existing upgrade hazard, but the installed storage configuration and safe recovery from an interrupted upgrade remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • observed — The declared admin API request surface remains codedang.com and stage.codedang.com at /graphql and /admin-api, forwarding to the same Service on port 3000. The source delta establishes no expansion of this configured surface; live acceptance and backend authorization are not established by these manifests.

Resilience and Maintainability Implications

  • inferred — The documented storage mismatch matters beyond availability because the n8n PVC preserves users, credentials, workflows, and execution metadata. Reusing the correct durable volume is therefore an identity and state-continuity requirement. The PR adds a precondition warning rather than introducing this dependency; installed volume ownership and recovery remain unverified.

Hardening Proposals

  • proposed — Before executing the existing upgrade procedure, verify the rendered PVC identity and installed ownership, preserve a recoverable database copy and encryption-key continuity, and establish recovery for a Pending replacement and a partial ingress cutover. Confirm the replacement HTTPRoute is accepted and serving before relying on it.

Explanation

The PR description says this change resolves HTTPRoute filename references in admin-api and client-api kustomization files. The whole-PR diff changes neither kustomization file and contains no client-api change. It reformats admin-api HTTPRoute YAML, removes a blank line from the MinIO route, and adds n8n upgrade warnings to infra/k8s/n8n/README.md. The MinIO and n8n changes have no connection to the stated conflict-resolution objective.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Include computed values in the comparison.

Without --all, helm get values does not dump computed values, so operators can miss chart defaults when reconciling the installed configuration with values.yaml. Add --all; Helm documents this option for dumping computed values. (docs.helm.sh)
