Add AppAPI Functionality to Nextloud (local docker socket)

[Jean28518]

This is what the AI said to me:

#!/bin/bash

# Exit immediately if a command exits with a non-zero status.
set -e

# ==============================================================================
# CONFIGURATION - PLEASE EDIT THESE VARIABLES
# ==============================================================================

# The absolute path to your Nextcloud installation's root directory.
# Example: "/var/www/html/nextcloud"
NEXTCLOUD_PATH="/var/www/nextcloud"

# The user that your web server (e.g., Apache, Nginx) runs as.
# On Debian/Ubuntu, this is typically 'www-data'. On CentOS/RHEL, it's 'apache' or 'httpd'.
WWW_USER="www-data"

# The full public URL of your Nextcloud instance. This must be reachable by the
# containers that will be deployed.
# Example: "https://cloud.mydomain.com"
NEXTCLOUD_URL="https://your-nextcloud-url.com"

# The name you want to give the HaRP Docker container.
HARP_CONTAINER_NAME="nextcloud-appapi-harp"

# The unique internal name for the deploy daemon in Nextcloud.
DAEMON_NAME="harp_proxy_local"

# (Optional) The GPU device to expose. Options: cpu | cuda | rocm
# Set to "cpu" if you don't have a dedicated GPU for this purpose.
COMPUTE_DEVICE="cpu"
