Starting Nextcloud​

Now lets start it up.

sudo docker compose up -d
info

the -d flag stands for detatched mode.

After its done pulling the docker images you can open up a web browser.

Before proceeding, you will need to configure your reverse proxy. I have an example Nginx config Here.

Connect to nextcloud by typing in your configured domain

You should see this screen.

Nextcloud Dashboard

Checking for errors and warnings​

On the top right click the User Icon and go to Administration Settings

Nextcloud Administration Settings

Here you should see Security & Setup Warnings

Nextcloud Warnings

In order to fix the Maintenance Window and the Phone Region warnings, we will have to edit our config.php file.

Modifying the config.php file​

Run the following command to open the config.php file with nano.

nano nextcloud/config/config.php
Hint

If you recieved an error Directory nextcloud doesnt exist, then you need to change directories.

Run cd /var/docker/nextcloud then try again.

Now add the following to the bottom of the file.

  'maintenance_window_start' => 1,
  'default_phone_region' => 'US',

Nextcloud config.php

Now if you go back to your Administration Settings Page.

It should look something like this.

Nextcloud No Warnings

HINT

In some cases, you may have to delete your browser cache and restart the browser for the Warnings to update.

Creating production use user​

Now you can go create a user for yourself.

Go to the user icon on the top right and select Users.
