Host is db  mariadb To find out, docker ps -a and see what matches nextcloud_db_1 ex: 8f867eda8f45   mariadb   "docker-entrypoint.s…"   2 minutes ago...

sudo nano /srv/path/NextCloud/config/config.php

edit   'overwrite.cli.url' => 'https://your.domain1.com',
ajout   'overwriteprotocol' => 'https',

Trusted domains:

Update to a newer version

Updating the Nextcloud container is done by pulling the new image, throwing away the old container and starting the new one.

It is only possible to upgrade one major version at a time. For example, if you want to upgrade from version 14 to 16, you will have to upgrade from version 14 to 15, then from 15 to 16.

Since all data is stored in volumes, nothing gets lost. The startup script will check for the version in your volume and the installed docker version. If it finds a mismatch, it automatically starts the upgrade process. Don't forget to add all the volumes to your new container, so it works as expected.

$ docker pull nextcloud
$ docker stop <your_nextcloud_container>
$ docker rm <your_nextcloud_container>
$ docker run <OPTIONS> -d nextcloud

Beware that you have to run the same command with the options that you used to initially start your Nextcloud. That includes volumes, port mapping.

When using docker-compose your compose file takes care of your configuration, so you just have to run:

$ docker-compose pull
$ docker-compose up -d
