Synology How to Install Nextcloud Using Docker

Nextcloud is a suite of client-server software for creating and using file hosting services. Nextcloud is free and open-source, which means that anyone is allowed to install and operate it on their own private server devices. In this step by step guide I will show you how to install Nextcloud on your Synology NAS using Docker & Portainer.

Note: This guide works perfectly with the latest Nextcloud 21.0.2 release.

After you paste the code in the Web editor, change the value for TZ (Select your current Time Zone from this list).
After you paste the code in the Web editor, change the value numbers for PUID and PGID with your own values. (Follow my step by step guide on how to do this.)
Note: If you have your docker folder in a different volume, then change /volume1/docker/nextcloud according to your settings. For example: /volume2/docker/nextcloud or /volume3/docker/nextcloud etc.
Note: If you decide to use mariaDB remember to change user, database, root password and database password.
