## 先 db 后 lobechat
```
## Postgres pgvector 数据库实例
docker network create pg
# First, create a named volume 持久化存储位置
docker volume create postgres_vector
# Then modify your run command to use the volume 
docker run --name pgvector \
  --network pg \
  -e POSTGRES_PASSWORD=密码密码_密码对应 \
  -p 4321:4321 \
  -v postgres_vector:/var/lib/postgresql/data \
  -d pgvector/pgvector:pg18


docker run -it -d -p 3210:3210 --network pg --env-file lobe-chat.env --name lobe-chat-database lobehub/lobe-chat-database

不太建议自建 SearXNG 还是用 exa + firecrawl
```
## Tailscale tailnet serve / funnel 使用  

Docs: https://tailscale.com/kb/1242/tailscale-serve

```
#tailscale funnel background process
tailscale funnel --bg 34321
#disable the proxy
tailscale funnel --https=443 off
```

Thanks!!!

As the DB pgvector update!

PostgreSQL 18+ now uses version-specific data directories (like /var/lib/postgresql/18/docker) instead of the generic /var/lib/postgresql/data. Your current mount configuration is causing a conflict. update claim

Key Change
Before: -v postgres_vector:/var/lib/postgresql/data
After: -v postgres_vector:/var/lib/postgresql
This allows PostgreSQL 18 to create its version-specific subdirectory (18/docker) automatically.

Need update pgvector command to below:

docker run --name pgvector \
  --network pg \
  -e POSTGRES_PASSWORD=密码密码_密码对应 \
  -p 4321:4321 \
  -v postgres_vector:/var/lib/postgresql \
  -d pgvector/pgvector:pg18
