I am using sensors to record temperature and humidity and the data is currently displaying properly in Debug, but I am unable to use the write file function to record these continually updated data to a specified .txt file.
It writes fine on my other windows computer, but not on this Ubuntu server, and I suspect it is a problem with the Ubuntu system files. Has this happened to anyone else?
as long as you are running it as user ace (so it has access to the /home/ace directory that looks ok. ( I would untick the creat directory option if you know the directory exists and you haven't added an extra path to the file name - but that won't make a difference to permissions).
Ah right. That is critical information :-). So yes you need to mount the host directory into the docker container and give it the correct permissions. I think you need to read up on how to do a bind-mount
