The proxy component that relays in-container application traffic (Jupyter, Terminal, TensorBoard, etc.) between the user's browser and the compute session. Renamed from WSProxy to App Proxy in the UI in FR-2841. The internal binary / daemon is still named wsproxy; only the user-facing label changed.
| Language | Term | Notes |
|---|---|---|
| English | App Proxy | Use "App Proxy (formerly WSProxy)" on first mention for users familiar with the old term. |
| Korean | App Proxy | UI 라벨은 영문 그대로 사용합니다. 처음 언급할 때 "App Proxy(이전 명칭 WSProxy)"로 적어 줍니다. |

Field labels (Resource Group settings):
| EN | KO | JA | TH |
|---|---|---|---|
| App Proxy Server Address | App Proxy 서버 주소 | App Proxy サーバアドレス | ที่อยู่เซิร์ฟเวอร์ App Proxy |
| App Proxy API Token | App Proxy API 토큰 | App Proxy APIトークン | โทเค็น API ของ App Proxy |
Do NOT use "WSProxy" as the user-facing label in new documentation. Keep wsproxy (lowercase, in code style) only when referring to the internal binary, daemon, or config key (e.g., wsproxy.proxyURL in config.toml).
| Term | Meaning |
|---|---|
| Container | The runtime environment of a compute session |
| Kernel image / Container image | The base image (snapshot) from which containers are created |
Do NOT use "container" and "kernel" interchangeably. They refer to different concepts.

|---|---|---|---|---|---|
| RBAC | RBAC | RBAC | RBAC | RBAC | Keep as abbreviation across all languages |
| Role | role | 권한 | ロール | บทบาท | A named set of permissions assignable to users |

| Permission Type | permission type | 권한 타입 | 権限タイプ | ประเภทสิทธิ์ | The category of resource a permission controls |
Note: The Korean i18n uses "권한" for both "Role" and "Permission" in different contexts. "세부 권한" is used specifically for fine-grained permissions within a role. Always check resources/i18n/ko.json for the exact UI labels.
| Role | EN | KO | JA | Scope |
|---|---|---|---|---|
| User | user | 사용자 | ユーザー | Standard access |
| Domain Admin | domain admin | 도메인 관리자 | ドメイン管理者 | Manages users and resources within a domain |
| Superadmin | superadmin | 슈퍼관리자 | スーパー管理者 | Full system access across all domains |
These terms match sidebar menu items. Keep documentation references consistent with actual UI labels.
