基于 docker 把 Label Studio 的 Django DB 从 SQLite 迁移到 PostgreSQL

# 1. 创建一个新的 Docker 网络，以便容器之间可以彼此通信
docker network create label-studio-net
 
# 2. 启动一个 PostgreSQL 容器，并设置必要的环境变量
docker run --rm -d --name label-studio-db \
  --network label-studio-net \
  -e POSTGRES_DB=label-studio \
  -e POSTGRES_USER=label-studio \
  -e POSTGRES_PASSWORD=label-studio \
  -v pgdata:/var/lib/postgresql/data \
  postgres:12-alpine
 
# 3. 停止并删除原来的 Label Studio 容器（如果有的话）
docker stop label-studio
docker rm label-studio
 
# 4. 启动一个新的 Label Studio 容器，使用之前创建的网络，并通过环境变量指定 PostgreSQL 数据库
docker run --rm -d --name label-studio \
  --network label-studio-net \
  -e LABEL_STUDIO_DB_HOST=label-studio-db \

  -e LABEL_STUDIO_DB_PASSWORD=label-studio \
