This is a critical step. You must configure your primary web server (Nginx, Apache, Caddy, Traefik, etc.) to route traffic from the /exapps path to your HaRP container.
Provide a new administrative username and a highly secure password.
Add the following line right before the closing array bracket ( ); ): 'memcache.local' => '\OC\Memcache\APCu', Use code with caution. 2. Set Up a Background Cron Job
Execute the following SQL commands. Replace Secure_Password_Here with a strong, unique alphanumeric passphrase. harp nextcloud install
Create a file named docker-compose.harp.yml in your Nextcloud installation directory (or wherever you manage your containers).
Note: Your Nextcloud path might be /var/www/html/nextcloud or /apps/www/nextcloud . Adjust accordingly.
If you want to run modern, high-performance applications alongside your Nextcloud—like AI backends or real-time collaborative tools—you’ll be dealing with the AppAPI and . However, the old ways of connecting Nextcloud to ExApps came with significant performance bottlenecks and configuration headaches. This is where HaRP changes everything. This is a critical step
Enable the configuration by creating a symlink to the active sites folder:
location ~ /harp/ limit_req zone=music burst=5;
CREATE USER nextcloud WITH PASSWORD 'secure_password'; CREATE DATABASE nextcloud_db OWNER nextcloud; GRANT ALL PRIVILEGES ON DATABASE nextcloud_db TO nextcloud; \q Use code with caution. Add the following line right before the closing
HaRP is a specialized reverse proxy system designed specifically for Nextcloud 32 and later. Its primary job is to act as a dedicated middleman, enabling direct and secure communication between a user's browser and External Apps (ExApps) running inside Docker containers.
sudo systemctl restart php8.2-fpm # Adjust to your PHP version sudo systemctl restart nginx # or apache2
(HaRP is the recommended standard for these versions). Docker and Docker Compose installed on your host. Administrative access to your Nextcloud instance. The AppAPI app installed from the Nextcloud App Store. 2. Deploying the HaRP Container
Nextcloud has introduced HaRP (HTTP Autoregister Reverse Proxy) to replace the older DockerSocketProxy method. HaRP allows External Apps (ExApps) to communicate directly with clients via WebSockets and high-performance proxies without taxing the main PHP stack. 1. Prerequisites
