Revised documentation to standardize use of 'bash docs/contribution/setup-fork.sh --full' for fork configuration, clarified install script execution flow, and updated JSON metadata template and field references. Improved helper function docs, resource requirements, and category lists. Updated references and instructions throughout for consistency and accuracy.

🤖 AI Contribution Guidelines for ProxmoxVE
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.

❌ 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/YourUsername/YourRepo/releases/latest | jq -r '.tag_name')
wget https://github.com/YourUsername/YourRepo/archive/${RELEASE}.tar.gz
tar -xzf ${RELEASE}.tar.gz
mv repo-${RELEASE} /opt/myapp
# ✅ CORRECT - use our function
fetch_and_deploy_gh_release "myapp" "YourUsername/YourRepo" "tarball" "latest" "/opt/myapp"
3. Custom Version-Check Logic
# ❌ WRONG - custom version check
CURRENT=$(cat /opt/myapp/version.txt)
LATEST=$(curl -s https://api.github.com/repos/YourUsername/YourRepo/releases/latest | jq -r '.tag_name')
if [[ "$CURRENT" != "$LATEST" ]]; then
# update...
fi
# ✅ CORRECT - use our function
if check_for_gh_release "myapp" "YourUsername/YourRepo"; 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" "YourUsername/YourRepo"
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" "tarball" "latest" "/opt/appname"
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" "tarball" "latest" "/opt/appname"
Functions with built-in messages (NEVER wrap in msg blocks):
fetch_and_deploy_gh_releasecheck_for_gh_releasesetup_nodejssetup_postgresql/setup_postgresql_dbsetup_mariadb/setup_mariadb_dbsetup_mongodbsetup_mysqlsetup_rubysetup_gosetup_javasetup_phpsetup_uvsetup_rustsetup_composersetup_ffmpegsetup_imagemagicksetup_gssetup_adminersetup_hwaccel
9. Creating Unnecessary System Users
# ❌ WRONG - LXC containers run as root, no separate user needed
useradd -m -s /usr/bin/bash appuser
chown -R appuser:appuser /opt/appname
sudo -u appuser npm install
# ✅ CORRECT - run directly as root
cd /opt/appname
$STD npm install
10. Using export in .env Files
# ❌ WRONG - export is unnecessary in .env files
cat <<EOF >/opt/appname/.env
export DATABASE_URL=postgres://...
export SECRET_KEY=abc123
export NODE_ENV=production
EOF
# ✅ CORRECT - simple KEY=VALUE format (files are sourced with set -a)
cat <<EOF >/opt/appname/.env
DATABASE_URL=postgres://...
SECRET_KEY=abc123
NODE_ENV=production
EOF
11. Using External Shell Scripts
# ❌ WRONG - external script that gets executed
cat <<'EOF' >/opt/appname/install_script.sh
#!/bin/bash
cd /opt/appname
npm install
npm run build
EOF
chmod +x /opt/appname/install_script.sh
$STD bash /opt/appname/install_script.sh
rm -f /opt/appname/install_script.sh
# ✅ CORRECT - run commands directly
cd /opt/appname
$STD npm install
$STD npm run build
12. Using sudo in LXC Containers
# ❌ WRONG - sudo is unnecessary in LXC (already root)
sudo -u postgres psql -c "CREATE DATABASE mydb;"
sudo -u appuser npm install
# ✅ CORRECT - use functions or run directly as root
PG_DB_NAME="mydb" PG_DB_USER="myuser" setup_postgresql_db
cd /opt/appname
$STD npm install
13. Unnecessary systemctl daemon-reload
# ❌ WRONG - daemon-reload is only needed when MODIFYING existing services
cat <<EOF >/etc/systemd/system/appname.service
# ... service config ...
EOF
systemctl daemon-reload # Unnecessary for new services!
systemctl enable -q --now appname
# ✅ CORRECT - new services don't need daemon-reload
cat <<EOF >/etc/systemd/system/appname.service
# ... service config ...
EOF
systemctl enable -q --now appname
14. Creating Custom Credentials Files
# ❌ WRONG - custom credentials file is not part of the standard template
msg_info "Saving Credentials"
cat <<EOF >~/appname.creds
Database User: ${DB_USER}
Database Pass: ${DB_PASS}
EOF
msg_ok "Saved Credentials"
# ✅ CORRECT - credentials are stored in .env or shown in final message only
# If you use setup_postgresql_db / setup_mariadb_db, a standard ~/[appname].creds is created automatically
15. Wrong Footer Pattern
# ❌ WRONG - old cleanup pattern with msg blocks
motd_ssh
customize
msg_info "Cleaning up"
$STD apt-get -y autoremove
$STD apt-get -y autoclean
msg_ok "Cleaned"
# ✅ CORRECT - use cleanup_lxc function
motd_ssh
customize
cleanup_lxc
16. Manual Database Creation Instead of Functions
# ❌ WRONG - manual database creation
DB_USER="myuser"
DB_PASS=$(openssl rand -base64 18 | tr -dc 'a-zA-Z0-9' | cut -c1-13)
$STD sudo -u postgres psql -c "CREATE ROLE $DB_USER WITH LOGIN PASSWORD '$DB_PASS';"
$STD sudo -u postgres psql -c "CREATE DATABASE mydb WITH OWNER $DB_USER;"
$STD sudo -u postgres psql -d mydb -c "CREATE EXTENSION IF NOT EXISTS postgis;"
# ✅ CORRECT - use setup_postgresql_db function
# This sets PG_DB_USER, PG_DB_PASS, PG_DB_NAME automatically
PG_DB_NAME="mydb" PG_DB_USER="myuser" PG_DB_EXTENSIONS="postgis" setup_postgresql_db
17. Writing Files Without Heredocs
# ❌ WRONG - echo / printf / tee
echo "# Config" > /opt/app/config.yml
echo "port: 3000" >> /opt/app/config.yml
printf "# Config\nport: 3000\n" > /opt/app/config.yml
cat config.yml | tee /opt/app/config.yml
# ✅ CORRECT - always use a single heredoc
cat <<EOF >/opt/app/config.yml
# Config
port: 3000
EOF

🔍 Checklist Before PR Creation
- No Docker installation used
fetch_and_deploy_gh_releaseused for GitHub releasescheck_for_gh_releaseused for update checkssetup_*functions used for runtimes (nodejs, postgresql, etc.)tools.funcfunctions NOT wrapped in msg_info/msg_ok blocks- No redundant variables (only when used multiple times)
$STDbefore all apt/npm/build commandsmsg_info/msg_ok/msg_errorfor logging (only for custom code)- Correct script structure followed (see templates)
- Update function present and functional (CT scripts)
- Data backup implemented in update function (if applicable)
motd_ssh,customize,cleanup_lxcat the end of install scripts- No custom download/version-check logic
- All links point to
community-scripts/ProxmoxVE(notProxmoxVED!) - JSON metadata file created in
frontend/public/json/<appname>.json - Category IDs are valid (0-25)
- Default OS version is Debian 13 or newer (unless special requirement)
- Default resources are reasonable for the application
💡 Tips for AI Assistants
- ALWAYS search
tools.funcfirst before implementing custom solutions - Use recent scripts as reference (Thingsboard, UniFi OS, Trip, Flatnotes, etc.)
- Ask when uncertain instead of introducing wrong patterns
- Test via GitHub - push to your fork and test with curl (not local bash)
bash -c "$(curl -fsSL https://raw.githubusercontent.com/YOUR_USERNAME/ProxmoxVE/main/ct/myapp.sh)" # Wait 10-30 seconds after pushing - GitHub takes time to update files - Consistency > Creativity - follow established patterns strictly
- Check the templates - they show the correct structure
- Don't wrap tools.func functions - they handle their own msg_info/msg_ok output
- Minimal variables - only create variables that are truly reused multiple times
- Always use $STD - ensures silent/non-interactive execution
- Reference good examples - look at recent additions in each category
🍒 Important: Cherry-Picking Your Files for PR Submission
⚠️ CRITICAL: When you submit your PR, you must use git cherry-pick to send ONLY your 3-4 files!
Why? Because setup-fork.sh modifies 600+ files to update links. If you commit all changes, your PR will be impossible to merge.
See: README.md - Cherry-Pick Section for complete instructions on:
- Creating a clean submission branch
- Cherry-picking only your files (ct/myapp.sh, install/myapp-install.sh, frontend/public/json/myapp.json)
- Verifying your PR has only 3 file changes (not 600+)
Quick reference:
# Create clean branch from upstream
git fetch upstream
git checkout -b submit/myapp upstream/main
# Cherry-pick your commit(s) or manually add your 3-4 files
# Then push to your fork and create PR
