ok, I try to use docker addon.
I install mariaDB docker addon and nexcloud docker add on.
when I configure nextcloud to use mariaDB, I use root as admin and no password.
nexcloud works fine.
My next step will be to use letsencrypt docker addon. But Nexcloud use 443 defaut port and letsencrypt/nginx use the same.
I read tuto (linuxserver.io) that explained to use port 444 for nextcloud and 443 for nginx. Then link nginx to forward 443 to 444, and change nexcloud domain. Can I do the same with docker addon? it is the limit of this basic addon?
Thanks
