All the latest NCP images use Deb11 and php7.4
Unfamiliar with Qnap, but as your using docker, I expect you can simply remove the container, pull the latest image and create a fresh container, with the same data folder(s).
I would still make backups of config and data files and folders, just in case, better safe than sorry
Sorry but I don’t understand why manually is not a solution if with “classic” it’s not too … Docker container doesn’t use phps global configuration … ?
I don’t understand and so sorry if it’s a weird question …
no they don’t - one of important reasons to user Docker or any other virtualization technology is to ship application with dependencies and run applications which might require different libs than you have available on the system.
Thanks for your quick answer and just to known : if in dockerfile is require a specific version to build container but it have no request to install it, the container in consequences couldn’t be launch or take global config of the server ? (It’s little redondant with your previous answer but it’s just a precision for me… )
