Maybe itis the screenshot only, but your double quotes look strange.

Try changing them to what is on your keyboard.

This doesn't look right

I copy the code from here : cloudnas/clouddrive - Docker Image | Docker Hub

please help me to check it

try this: https://codebeautify.org/yaml-validator

Or put the code in a code box. This forum does not support markdown.

I tried this tool and it displays valid,but I got same error when copy them into stack of portainer.

I think portainer does not support "version: "2.1"", only support "version: "2""

your first line in volumes has two :

yes, thanks a lot

Quote from Zoki

If your portainer does not support version 3 you are on the old image. Time to upgrade

Image name changed.
