Proxy Provider 연동 상세

NPM의 백엔드를 10.89.0.20:9000 (Authentik Embedded Outpost)으로 설정한다. Outpost가 Host 헤더를 보고 어느 Proxy Provider를 적용할지 결정한다.

NPM (443) ─→ Authentik Outpost (10.89.0.20:9000)
                    │
                    ├─ Host: prometheus.du5t.xyz  → 10.89.0.30:9090
                    ├─ Host: file.du5t.xyz        → 10.89.0.5:8080
                    └─ Host: comfy.du5t.xyz       → 10.89.0.1:8188

API 토큰 재발급

Authentik API 토큰은 만료 시 재발급이 필요하다.

podman exec authentik-worker python -m manage shell -c "
from authentik.core.models import Token, TokenIntents, User
user = User.objects.get(username='akadmin')
t = Token.objects.filter(identifier='cli-admin-token').first()
if t: t.delete()
token = Token.objects.create(
    identifier='cli-admin-token', user=user, intent=TokenIntents.INTENT_API
)
print(token.key)
"

신규 서비스 Authentik 연동 절차

OIDC 방식

1. Authentik API: POST /api/v3/providers/oauth2/ — Provider 생성
2. Authentik API: POST /api/v3/core/applications/ — Application 생성
3. 서비스 측 OIDC 설정 (Discovery URL 패턴: https://auth.du5t.xyz/application/o/<slug>/.well-known/openid-configuration)

Proxy Provider 방식

1. Authentik API: POST /api/v3/providers/proxy/ — Provider 생성 (external_host, internal_host 지정)
2. Authentik API: POST /api/v3/core/applications/ — Application 생성
3. Authentik API: PATCH /api/v3/outposts/instances/999d7409-.../ — Outpost providers 배열에 추가
4. NPM DB: UPDATE proxy_host SET forward_host='10.89.0.20', forward_port=9000 WHERE domain_names='...'
5. NPM nginx conf 파일 직접 수정 후 podman exec npm-app nginx -s reload

미적용 서비스 (향후 계획)

서비스	권장 방식	비고
JupyterHub	OIDC (oauthenticator.GenericOAuthenticator)	jupyterhub_config.py 수정 필요
SFTPGo	OIDC (Web Admin > Settings > OIDC)	웹 UI에서 설정 가능
Jellyfin	OIDC (SSO Plugin)	플러그인 설치 필요
Ollama API	Proxy Provider	현재 무인증 노출 상태
