用docker+portainer 10分鐘快速部署 nextcloud v22.2.3 最新版

採用nextcloud官方的Stack的basic版本，進行安裝
選用的版本 nextcloud 22.2.3 apache+mysql(miriadb)的版本

安裝過程中，沒有太多的問題
如果有遇到下面的異常再排除就好

過程中重覆安裝時，會出現下面的資料(reinstall時，nextcloud設定正確不會掉資料)
Error. It looks like you are trying to reinstall your NextCloud. However the file CAN_INSTALL is missing from your config directory. Please create the file CAN_INSTALL in your config folder to continue.
在config的目錄中執行下面的指令
touch CAN_INSTALL

Error while trying to create admin user: Failed to connect to the database: An exception occurred in the driver: SQLSTATE[HY000] [2002] No such file or directory
DBServer 把localhost 改成 db即可

完整的stack如下，修改紅色的部份即可
會這樣stack設定
可以單獨備份nextcloud的設定檔/app/資料庫/上傳的檔案/佈景主題等等
所以災難復原時，放回去，再config touch CAN_INSTALL 設定正確
資料應該就會回來
