In terms of permissions to folders in the container I followed the recipe of the provided dockerfile which is this line:
chmod 777 ./una/inc ./una/cache ./una/cache_public ./una/logs ./una/tmp ./una/storage \ && chmod +x ./una/plugins/ffmpeg/ffmpeg.exe
Is there anything missing?

In terms of studio side, I just checked for all of the paths the current status is the same as the desired status

Prior to deploying the application to a docker container the uploading of pictures and videos was working well locally. This only occurred after I deployed it. Forgot to update this at the previous comment. Could there be some other configurations or settings I would need to change since the uploading is not truly local now. I am accessing the site through host machine browser and the site is currently hosted in the docker container. May I know what can I do in this situation?
