Deploy with Docker, Coolify and Nginx

The update server can run on Docker, Coolify or a standalone Nginx host. Configure it through /admin.

Docker and Coolify#

1. Add FluxWP/updater to Coolify or clone it.
2. Select the Dockerfile build pack.
3. Mount persistent storage at /var/www/html/data for settings, statistics and ZIP cache.
4. Configure the domain and SSL and complete setup at https://<domain>/admin.

For local use, the repository includes docker-compose.yml:

docker compose up -d

Configuration#

Use the panel to enter repository, token and server settings. Keep credentials out of the repository. If deploying through Coolify, store any deployment credentials as secrets.

Nginx#

Apache includes .htaccess rules. On Nginx deny access to configuration, data, libraries and hidden files and forward application routes to index.php:

location ~ ^/(config\.php|config\.sample\.php|lib/|data/|bin/|\.) { deny all; }
location / { try_files $uri /index.php$is_args$args; }
location = /index.php {
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root/index.php;
    fastcgi_pass php;
}

After setup, verify that /data/settings.json returns 403 and /admin shows the login screen.
