Title: Runbook — Open WebUI (vLLM, Caddy 7500)

• Service Ports: Caddy listens on :7500 and reverse-proxies to Open WebUI at 127.0.0.1:17500.
• vLLM: OpenAI-compatible API on 127.0.0.1:8001 (/v1).

Manual start (no supervisor/systemd):

• Environment:
  • DATA_DIR=/data/adaptai/migrate/vast/workspace-vast1-2/webui
  • DATABASE_URL=sqlite:////data/adaptai/migrate/vast/workspace-vast1-2/webui/webui.db
  • OPENAI_API_BASE_URL=http://127.0.0.1:8001/v1
  • ENABLE_PERSISTENT_CONFIG=True
  • WEBUI_AUTH=False
• Command:
  • /venv/main/bin/open-webui serve --host 127.0.0.1 --port 17500

Using the existing script:

• sudo env WEBUI_AUTH=False ENABLE_PERSISTENT_CONFIG=True OPENAI_API_BASE_URL=http://127.0.0.1:8001/v1 DATA_DIR=/data/adaptai/migrate/vast/workspace-vast1-2/webui DATABASE_URL=sqlite:////data/adaptai/migrate/vast/workspace-vast1-2/webui/webui.db PROC_NAME=open_webui OPENWEBUI_ARGS="--host 127.0.0.1 --port 17500" /opt/supervisor-scripts/open_webui.sh

Verification:

• ss -tulpen | rg ":17500\b" — Open WebUI is listening.
• Load http://localhost:7500 — should proxy to Open WebUI.

DB basics:

• SQLite absolute path for Peewee requires four slashes: sqlite:////abs/path/to/webui.db.
• Config writes live in config.data JSON (e.g., MODEL_ORDER_LIST, DEFAULT_MODELS, WEBUI_AUTH).
