Nextcloud

A self-hosted file sync and share platform, replacing Google Drive and Dropbox with extensive plugin support.

Review notes

PHP and database configuration must be correct. Use PostgreSQL for production, set up cron jobs and Redis for better performance.

Deployment guide

Run with Docker Compose using PostgreSQL and Redis. Domain and trusted_domains must be configured correctly.

Create data and config directories for Nextcloud.
Run Docker Compose with Nextcloud, PostgreSQL, and Redis.
Access the web UI, create an admin account, and configure trusted_domains.
Set up cron jobs (system cron or webcron) for background tasks.
Put HTTPS reverse proxy in front and configure overwrite.cli.url.

Backup:Back up the data directory, PostgreSQL database, and config.php. Test restores regularly.

Copy and run on your server

Use each block separately: save the compose file, or copy the bash script to create it and start the container.
