wiki(concepts): ingest ocis-on-vds-deploy-recipe + entity refresh

New concept page documents the oCIS-on-VDS deploy pattern with the 4
non-obvious gotchas surfaced during owncloud-vds-deploy:

  1. UID mismatch — image ocis-user is 1000, host vitya is 1001 →
     compose `user: "1001:1001"` override (alt chown rejected as orphan-UID)
  2. PROXY_TLS=false — explicit per docs when reverse proxy terminates HTTPS
  3. PROXY_ENABLE_BASIC_AUTH=true — required for WebDAV/LibreGraph API
  4. LibreGraph POST /graph/v1.0/users — only way to create users (no CLI)

Plus decomposedfs storage layout, atomic-revert recipe, backup integration
note. Source: .tasks/owncloud-vds-deploy.md.

entities/vds-kzntsv.md updated: stack table + hostnames + file layout
include owncloud row.

index.md catalog + log.md ingest entry refreshed.

+# oCIS на VDS — deploy recipe + non-obvious gotchas
+
+Recipe для разворачивания **ownCloud Infinite Scale** (oCIS) — Go-based замены classic ownCloud Server 10 — в Docker за traefik с LetsEncrypt. Применимо на [[vds-kzntsv]] и других хостах с тем же pattern'ом (`/opt/stacks/<name>/`, traefik network `proxy`, LE certresolver `letsEncrypt`).
+
+Validated 2026-05-21 на image `owncloud/ocis:7.1.0`. Container запустился, traefik routes 200 OK, LibreGraph API + WebDAV работают, init создаёт admin + idm.json в `data/idm/`.
+
+## Когда применять
+
+- Личный personal-cloud для одного пользователя (single binary, no external DB)
+- Replace мёртвого / legacy ownCloud Server 10 (oCIS = main line от ownCloud GmbH, OC10 deprecating)
+- Files-only use-case (calendar/contacts не нужны — для тех нужен Nextcloud)
+- На хосте с уже работающим traefik + LE certresolver (recipe рассчитан на termination upstream)
+
+## Когда **не** применять
+
+- Multi-tenant корпоративная инсталляция → нужны external IDP, OIDC chain, не личный setup
+- Нужны calendar / contacts / mail / collabora → Nextcloud, не oCIS
+- Block-level dedup критичен → Seafile (oCIS использует file-level decomposedfs)
+- Host UID = 1000 (image uid 1000 matches → `user:` override **не** нужен)
+
+## Compose recipe
+
+`/opt/stacks/owncloud/docker-compose.yml`:
+
+```yaml
+services:
+  ocis:
+    image: owncloud/ocis:7.1.0
+    container_name: owncloud
+    restart: unless-stopped
+    user: "1001:1001"                 # ← gotcha 1, см. ниже
+    entrypoint: /bin/sh
+    command: ["-c", "ocis init || true; exec ocis server"]
+    environment:
+      OCIS_URL: https://owncloud.kzntsv.site
+      OCIS_LOG_LEVEL: info
+      OCIS_LOG_COLOR: "false"
+      PROXY_TLS: "false"              # ← gotcha 2
+      PROXY_ENABLE_BASIC_AUTH: "true" # ← gotcha 3
+      OCIS_INSECURE: "false"
+      IDM_CREATE_DEMO_USERS: "false"
+      IDM_ADMIN_PASSWORD: ${OCIS_ADMIN_PASSWORD}
+    volumes:
+      - ./data:/var/lib/ocis
+      - ./config:/etc/ocis
+    networks: [proxy]
+    labels:
+      - traefik.enable=true
+      - "traefik.http.routers.owncloud.rule=Host(`owncloud.kzntsv.site`)"
+      - traefik.http.routers.owncloud.entrypoints=websecure
+      - traefik.http.routers.owncloud.tls.certresolver=letsEncrypt
+      - traefik.http.services.owncloud.loadbalancer.server.port=9200
+
+networks:
+  proxy: { external: true }
+```
+
+`/opt/stacks/owncloud/.env` (chmod 600):
+```
+OCIS_ADMIN_PASSWORD=<32+ random chars, store в pass owncloud/admin-password>
+```
+
+## Gotcha 1: UID mismatch image vs host
+
+Image `owncloud/ocis` runs as **UID 1000** (`ocis-user` внутри контейнера). Если host-side user-owner mounted dirs ≠ 1000 — контейнер падает в restart-loop с:
+
+```
+Could not create config: open /etc/ocis/ocis.yaml: permission denied
+The jwt_secret has not been set properly in your config for ocis.
+```
+
+«jwt_secret has not been set» — **обманка**, симптом сидит на ровном месте perm-deny при попытке записать ocis.yaml на первом `ocis init` пробеге.
+
+**Fix:** `user: "<host-uid>:<host-gid>"` override в compose. На vds-kzntsv host user `vitya` = UID 1001 → `user: "1001:1001"`. Альтернатива (`chown 1000` host-dirs) **отвергнута**: создаёт orphan UID на хосте, путает auditing + backup tools.
+
+**Diagnose UID:** `stat -c "%u:%g %U:%G" /opt/stacks/owncloud/config`.
+
+## Gotcha 2: `PROXY_TLS=false` за reverse proxy
+
+Дефолт oCIS — `PROXY_TLS=true` (HTTPS на proxy port 9200 self-signed). За traefik, который сам терминирует HTTPS, это даёт двойную TLS-обёртку — traefik пытается сделать backend TLS, не получается.
+
+Per ownCloud docs: «If a reverse proxy is used to terminate HTTPS, `PROXY_TLS` can be set to false, though this means communication between the proxy and Infinite Scale will be unencrypted.» На том же хосте, в bridge network — acceptable.
+
+## Gotcha 3: `PROXY_ENABLE_BASIC_AUTH=true` для WebDAV + admin API
+
+Дефолтно oCIS — OIDC-only (browser-based login). Для **rclone / ownCloud-desktop / curl LibreGraph API** нужен basic auth — иначе 401 везде, включая `GET /graph/v1.0/me`.
+
+**Trade-off:** basic auth не имеет MFA/refresh-tokens. Для personal use acceptable. Для shared deployment — обернуть LDAP / OIDC отдельно.
+
+## Gotcha 4: User-create via LibreGraph API (нет CLI)
+
+oCIS **не** имеет `ocis idm user add` или подобной CLI команды. Создание users — только через:
+
+1. Web UI как admin → Settings → Users
+2. LibreGraph API: `POST /graph/v1.0/users` с basic auth admin'а
+
+API recipe:
+```bash
+curl -u "admin:$ADMIN_PWD" -X POST \
+  "https://owncloud.kzntsv.site/graph/v1.0/users" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "displayName": "Vitya",
+    "onPremisesSamAccountName": "vitya",
+    "mail": "vitya@kzntsv.site",
+    "passwordProfile": {"password": "<random-32>"},
+    "accountEnabled": true
+  }'
+```
+→ HTTP 201 с user JSON (с `id` UUID).
+
+List users: `GET /graph/v1.0/users`.
+
+## Storage layout (decomposedfs)
+
+После `ocis init` data dir выглядит так:
+
+```
+/opt/stacks/owncloud/data/
+├── idm/           — internal IDM (LDAP-style) state
+├── idp/           — OIDC IdP private keys (private-key.pem etc)
+├── nats/          — internal pub-sub messaging
+├── search/        — indexer state (bleve)
+└── storage/
+    ├── metadata/spaces/<2>/<rest>/  — space metadata
+    └── users/spaces/<2>/<rest>/     — actual user files (decomposedfs nodes)
+```
+
+Каждый user space = `<2-char-prefix>/<26-char-rest-of-uuid>/` (split UUID для FS spread). Files внутри хранятся как **plain bytes** + sidecar metadata (xattrs / .meta.json). Backup-friendly: tar+rsync захватит всё корректно, восстановление = просто разархивировать обратно.
+
+Internal KV-store (`storage/users/spaces/.../metadata/`, `idm/idm.json`, etc.) — **JSON files**, не БД. Это и есть «no external DB needed» — oCIS использует filesystem + NATS вместо Postgres/Redis.
+
+## Backup integration
+
+`/opt/stacks/owncloud` (whole dir) добавлен в rsync source list [[vds-backup-rsync-kreknin]]:
+
+```diff
+   /opt/stacks/backup \
++  /opt/stacks/owncloud \
+   /etc/ssh \
+```
+
+Live container во время rsync — acceptable trade-off (decomposedfs использует atomic rename, отдельные node-files не corrupt'ятся). Если требуется strictly consistent snapshot — `docker stop owncloud` → rsync → `docker start` (downtime ~30s).
+
+Первый full backup snapshot после import → +~25 GB на kreknin. Далее hardlink-incremental ≈ 1 GB/day.
+
+## Connection chain
+
+```
+DNS owncloud.kzntsv.site → 89.253.255.94 (VDS_IP)
+  → ufw 443
+  → traefik websecure (LE cert via letsEncrypt resolver)
+  → docker network proxy (172.18.0.0/16)
+  → container owncloud:9200 (oCIS proxy service)
+  → internal services: idp / idm / users / groups / proxy / storage-system / sharing / search ...
+```
+
+## Atomic revert
+
+```bash
+ssh vitya@89.253.255.94 'cd /opt/stacks/owncloud && docker compose down -v && cd .. && rm -rf owncloud'
+# rsync source list cleanup (revert):
+ssh vitya@89.253.255.94 "sed -i '\\|/opt/stacks/owncloud|d' /opt/stacks/backup/scripts/run.sh"
+# secrets cleanup:
+pass rm owncloud/admin-password owncloud/user-vitya && pass git push
+```
