Raw Blame History

🤖 AI Contribution Guidelines for ProxmoxVED

This documentation is intended for all AI assistants (GitHub Copilot, Claude, ChatGPT, etc.) contributing to this project.

🎯 Core Principles

1. Maximum Use of `tools.func` Functions

We have an extensive library of helper functions. NEVER implement your own solutions when a function already exists!

2. No Pointless Variables

Only create variables when they:

Are used multiple times
Improve readability
Are intended for configuration

3. Consistent Script Structure

All scripts follow an identical structure. Deviations are not acceptable.

4. Bare-Metal Installation

We do NOT use Docker for our installation scripts. All applications are installed directly on the system.

📁 Script Types and Their Structure

❌ Anti-Patterns (NEVER use!)

1. Pointless Variables

# ❌ WRONG - unnecessary variables
APP_NAME="myapp"
APP_DIR="/opt/${APP_NAME}"
APP_USER="root"
APP_PORT="3000"
cd $APP_DIR

# ✅ CORRECT - use directly
cd /opt/myapp

2. Custom Download Logic

# ❌ WRONG - custom wget/curl logic
RELEASE=$(curl -s https://api.github.com/repos/owner/repo/releases/latest | jq -r '.tag_name')
wget https://github.com/owner/repo/archive/${RELEASE}.tar.gz
tar -xzf ${RELEASE}.tar.gz
mv repo-${RELEASE} /opt/myapp

# ✅ CORRECT - use our function
fetch_and_deploy_gh_release "myapp" "owner/repo"

3. Custom Version-Check Logic

# ❌ WRONG - custom version check
CURRENT=$(cat /opt/myapp/version.txt)
LATEST=$(curl -s https://api.github.com/repos/owner/repo/releases/latest | jq -r '.tag_name')
if [[ "$CURRENT" != "$LATEST" ]]; then
  # update...
fi

# ✅ CORRECT - use our function
if check_for_gh_release "myapp" "owner/repo"; then
  # update...
fi

4. Docker-based Installation

# ❌ WRONG - using Docker
docker pull myapp/myapp:latest
docker run -d --name myapp myapp/myapp:latest

# ✅ CORRECT - Bare-Metal Installation
fetch_and_deploy_gh_release "myapp" "owner/repo"
npm install && npm run build

5. Custom Runtime Installation

# ❌ WRONG - custom Node.js installation
curl -fsSL https://deb.nodesource.com/setup_22.x | bash -
apt install -y nodejs

# ✅ CORRECT - use our function
NODE_VERSION="22" setup_nodejs

6. Redundant echo Statements

# ❌ WRONG - custom logging messages
echo "Installing dependencies..."
apt install -y curl
echo "Done!"

# ✅ CORRECT - use msg_info/msg_ok
msg_info "Installing Dependencies"
$STD apt install -y curl
msg_ok "Installed Dependencies"

7. Missing $STD Usage

# ❌ WRONG - apt without $STD
apt install -y nginx

# ✅ CORRECT - with $STD for silent output
$STD apt install -y nginx

8. Wrapping `tools.func` Functions in msg Blocks

# ❌ WRONG - tools.func functions have their own msg_info/msg_ok!
msg_info "Installing Node.js"
NODE_VERSION="22" setup_nodejs
msg_ok "Installed Node.js"

msg_info "Updating Application"
CLEAN_INSTALL=1 fetch_and_deploy_gh_release "appname" "owner/repo"
msg_ok "Updated Application"

# ✅ CORRECT - call directly without msg wrapper
NODE_VERSION="22" setup_nodejs

CLEAN_INSTALL=1 fetch_and_deploy_gh_release "appname" "owner/repo"

Functions with built-in messages (NEVER wrap in msg blocks):

fetch_and_deploy_gh_release
check_for_gh_release
setup_nodejs
setup_postgresql / setup_postgresql_db
setup_mariadb / setup_mariadb_db
setup_mongodb
setup_mysql
setup_ruby
setup_go
setup_java
setup_php
setup_uv
setup_rust
setup_composer
setup_ffmpeg
setup_imagemagick
setup_gs
setup_adminer
setup_hwaccel

📝 Important Rules

Variable Declarations (CT Script)

# Standard declarations (ALWAYS present)
APP="AppName"
var_tags="${var_tags:-tag1;tag2}"
var_cpu="${var_cpu:-2}"
var_ram="${var_ram:-2048}"
var_disk="${var_disk:-8}"
var_os="${var_os:-debian}"
var_version="${var_version:-13}"
var_unprivileged="${var_unprivileged:-1}"

Update-Script Pattern

function update_script() {
  header_info
  check_container_storage
  check_container_resources

  # 1. Check if installation exists
  if [[ ! -d /opt/appname ]]; then
    msg_error "No ${APP} Installation Found!"
    exit
  fi

  # 2. Check for update
  if check_for_gh_release "appname" "owner/repo"; then
    # 3. Stop service
    msg_info "Stopping Service"
    systemctl stop appname
    msg_ok "Stopped Service"

    # 4. Backup data (if present)
    msg_info "Backing up Data"
    cp -r /opt/appname/data /opt/appname_data_backup
    msg_ok "Backed up Data"

    # 5. Perform clean install
    CLEAN_INSTALL=1 fetch_and_deploy_gh_release "appname" "owner/repo"

    # 6. Rebuild (if needed)
    cd /opt/appname
    $STD npm install
    $STD npm run build

    # 7. Restore data
    msg_info "Restoring Data"
    cp -r /opt/appname_data_backup/. /opt/appname/data
    rm -rf /opt/appname_data_backup
    msg_ok "Restored Data"

    # 8. Start service
    msg_info "Starting Service"
    systemctl start appname
    msg_ok "Started Service"
    msg_ok "Updated successfully!"
  fi
  exit  # IMPORTANT: Always end with exit!
}

Systemd Service Pattern

msg_info "Creating Service"
cat <<EOF >/etc/systemd/system/appname.service
[Unit]
Description=AppName Service
After=network.target

[Service]
Type=simple
User=root
WorkingDirectory=/opt/appname
Environment=NODE_ENV=production
ExecStart=/usr/bin/node /opt/appname/server.js
Restart=on-failure
RestartSec=5

[Install]
WantedBy=multi-user.target
EOF
systemctl enable -q --now appname
msg_ok "Created Service"

Installation Script Footer

# ALWAYS at the end of the install script:
motd_ssh
customize
cleanup_lxc

🔍 Checklist Before PR Creation

No Docker installation used
fetch_and_deploy_gh_release used for GitHub releases
check_for_gh_release used for update checks
setup_* functions used for runtimes (nodejs, postgresql, etc.)
tools.func functions NOT wrapped in msg_info/msg_ok blocks
No redundant variables
$STD before all apt/npm/build commands
msg_info/msg_ok/msg_error for logging (only for custom code)
Correct script structure followed
Update function present and functional
Data backup implemented in update function
motd_ssh, customize, cleanup_lxc at the end
No custom download/version-check logic
JSON metadata file created in frontend/public/json/<appname>.json

📖 Reference: Good Example (Termix)

CT Script: ct/termix.sh

Uses check_for_gh_release for version checking
Uses CLEAN_INSTALL=1 fetch_and_deploy_gh_release for clean updates
Backup/restore of /opt/termix/data
Correct structure with all required variables

Install Script: install/termix-install.sh

NODE_VERSION="22" setup_nodejs instead of manual installation
fetch_and_deploy_gh_release "termix" "Termix-SSH/Termix" instead of wget/curl
Clean service configuration
Correct footer with motd_ssh, customize, cleanup_lxc

<EFBFBD> JSON Metadata Files

Every application requires a JSON metadata file in frontend/public/json/<appname>.json.

<EFBFBD>💡 Tips for AI Assistants

Search tools.func first before implementing custom solutions
Use existing scripts as reference (e.g., linkwarden-install.sh, homarr-install.sh)
Ask when uncertain instead of introducing wrong patterns
Consistency > Creativity - follow established patterns
Test local variables - use ${VAR:-default} pattern for optional values
