uid=82(www-data) gid=82(www-data) groups=82(www-data),82(www-data)

entrypoint have not migrated file perms

We do not support simple switching between the different variants (apache, fpm, fpm-alpine).
Doing so is like migrating, which means you have to fix the permissions manually.
(docker-compose exec app chown -R www-data:www-data /var/www/html)

I just migrated to fpm-alpine. For those who find this issue and want to achieve the same: The above fix is not correct. You have to do the following to make everything work again:

docker-compose exec app chown -R www-data:root /var/www

This corresponds to https://github.com/nextcloud/docker/blob/783232840a16a3f9100da526edf8ca597800ac2a/Dockerfile-alpine.template#L83 for a fresh install and sets correct gid/uid for both html and data folders.

for my future self, that it is chown -R 82:0 /var/www if you happen to have this mounted as a nfs share for k8s
