Nextcloud (Docker Compose)

Build a Nextcloud instance in Docker Compose complete with PostgreSQL and Redis

Prerequisites

1. Docker
2. Docker Compose
3. A reverse proxy on its own Docker network

Setup

1. Create a copy of .env.example:

cp .env.example .env

2. Replace the NEXTCLOUD_HOST variable with your desired domain

3. Replace VOLUME_PATH variable if you wish to change where volume data is stored

4. Modify other variables as needed

5. Create the following required secrets files (you should consider restricting access to these files):

• secrets/postgres_password.txt
• secrets/nextcloud_admin_user.txt
• secrets/nextcloud_admin_password.txt

# Postgres
echo "SuperSecretPassword" > secrets/postgres_password.txt # Replace with your own super secret password

# Nextcloud
echo "admin" > secrets/nextcloud_admin_user.txt                   # Replace with desired admin username
echo "SuperSecretPassword" > secrets/nextcloud_admin_password.txt # Replace with super secret password for admin Nextcloud user

6. Bring up the containers!

sudo docker-compose -p nextcloud up --build -d

7. (Optional) To enable some file previews copy previews.config.php into your Nextcloud's config directory (replace $volume with the path you have set in the VOLUME_PATH environment variable):

sudo cp nextcloud/previews.config.php $volume/var/www/html/config/
sudo chown www-data:root $volume/var/www/html/config/previews.config.php
