1. 升級前準備工作
1.1 數據備份：
進入原安裝包 docker 目錄，備份“volumes”文件夾，此文件夾包含了 Dify 數據庫數據：
root@joe:/usr/local/dify/docker/volumes# pwd
/usr/local/dify/docker/volumes
root@joe:/usr/local/dify/docker# tar -czvf volumes.tar.gz volumes/
root@joe:/usr/local/dify/docker# ll

root@joe:/usr/local/dify/docker# cp volumes.tar.gz /opt/dify1.4.2/
1.2 備份配置文件（.env 和 docker-compose.yml）：
root@joe:/usr/local/dify/docker# cp .env .env.bak
root@joe:/usr/local/dify/docker# cp docker-compose.yaml docker-compose.yaml.bak
root@joe:/usr/local/dify/docker# cp .env.bak /opt/dify1.4.2/
root@joe:/usr/local/dify/docker# cp docker-compose.yaml.bak /opt/dify1.4.2/1.3 停止服務
root@joe:/usr/local/dify/docker# docker compose down
2. 執行升級
以下是基于 Docker 安裝的 Dify 版本升級步驟：
下載最新版本代碼（如從 GitHub）并解壓。
2.1 上傳文件
2.2 加壓文件
root@joe:/usr/local# tar -zxvf dify-1.5.0.tar.gz
2.3 復制文件
root@joe:/usr/local# cp -rf dify/docker/volumes/ dify-1.5.0/docker/volumes/
root@joe:/usr/local# cp -rf dify/docker/.env dify-1.5.0/docker/2.4 刪除源文件目錄并且替換新的
oot@joe:/usr/local# ll
