| Network Config | /etc/network/ or Netplan | /etc/network/interfaces |
| IPv6 Setup | netplan files | /etc/network/interfaces |
| Auto-Login | getty override | `/etc/inittab` or shell config |
| Size | ~200MB | ~100MB |
## Execution Flow for Alpine
```
Alpine Container Started
↓
source $FUNCTIONS_FILE_PATH
↓
setting_up_container() ← Alpine setup message
↓
update_os() ← apk update
↓
verb_ip6() ← IPv6 configuration (optional)
↓
network_check() ← Verify connectivity
↓
[Application-Specific Installation]
↓
motd_ssh() ← Configure SSH/MOTD
customize() ← Apply customizations
↓
cleanup_lxc() ← Final cleanup
↓
Alpine Installation Complete
```
## Common Usage Patterns
### Basic Alpine Setup
```bash
#!/usr/bin/env bash
source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
setting_up_container
update_os
# Install Alpine-specific packages
apk add --no-cache curl wget git
# ... application installation ...
motd_ssh
customize
cleanup_lxc
```
### With IPv6 Enabled
```bash
#!/usr/bin/env bash
source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
setting_up_container
verb_ip6
update_os
network_check
# ... application installation ...
motd_ssh
customize
cleanup_lxc
```
### Installing Services
```bash
#!/usr/bin/env bash
source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
setting_up_container
update_os
# Install via apk
apk add --no-cache nginx
# Enable and start service on Alpine
rc-update add nginx
rc-service nginx start
motd_ssh
customize
cleanup_lxc
```
## Best Practices
### ✅ DO
- Use `apk add --no-cache` to reduce image size
- Enable IPv6 if application needs it (`verb_ip6`)
- Use `rc-service` for service management on Alpine
- Check `/etc/network/interfaces` for IPv6 persistence
- Test network connectivity before critical operations
- Use `$STD` for output suppression in production
### ❌ DON'T
- Use `apt-get` commands (Alpine doesn't have apt)
- Use `systemctl` (Alpine uses OpenRC, not systemd)
- Use `service` command (it may not exist on Alpine)
- Assume systemd exists on Alpine
- Forget to add `--no-cache` flag to `apk add`
- Hardcode paths from Debian (different on Alpine)
## Alpine-Specific Considerations
### Package Names
Some packages have different names on Alpine:
```bash
# Debian → Alpine
# curl → curl (same)
# wget → wget (same)
# python3 → python3 (same)
# libpq5 → postgresql-client
# libmariadb3 → mariadb-client
```
### Service Management
```bash
# Debian (systemd) → Alpine (OpenRC)
systemctl start nginx → rc-service nginx start
systemctl enable nginx → rc-update add nginx
systemctl status nginx → rc-service nginx status
```
### Network Configuration
```bash
# Debian (Netplan) → Alpine (/etc/network/interfaces)
/etc/netplan/01-*.yaml → /etc/network/interfaces
netplan apply → Configure directly in interfaces
# Enable IPv6 persistently on Alpine:
# Add to /etc/network/interfaces:
# iface eth0 inet6 static
# address <IPv6_ADDRESS>
```
## Troubleshooting
### "apk command not found"
- This is Alpine Linux, not Debian
- Install packages with `apk add` instead of `apt-get install`
- Example: `apk add --no-cache curl wget`
### "IPv6 not persisting after reboot"
- IPv6 must be configured in `/etc/network/interfaces`
- The `verb_ip6()` function handles this automatically
- Verify: `cat /etc/network/interfaces`
### "Service won't start on Alpine"
- Alpine uses OpenRC, not systemd
- Use `rc-service nginx start` instead of `systemctl start nginx`
- Enable service: `rc-update add nginx`
- Check logs: `/var/log/` or `rc-service nginx status`
### "Container too large"
- Alpine should be much smaller than Debian
- Verify using `apk add --no-cache` (removes package cache)
- Example: `apk add --no-cache nginx` (not `apk add nginx`)

## Alpine vs Debian Package Differences
| Package | Debian | Alpine |
|---------|:---:|:---:|
| nginx | `apt-get install nginx` | `apk add nginx` |
| mariadb | `apt-get install mariadb-server` | `apk add mariadb` |
| PostgreSQL | `apt-get install postgresql` | `apk add postgresql` |
| Node.js | `apt-get install nodejs npm` | `apk add nodejs npm` |
| Docker | Special setup | `apk add docker` |
| Python | `apt-get install python3 python3-pip` | `apk add python3 py3-pip` |
## Common Usage Patterns
### Basic Alpine Tool Installation
```bash
#!/usr/bin/env bash
source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
# Update package lists
apk_update
# Install nginx
apk_add nginx
# Start service
rc-service nginx start
rc-update add nginx
```
### With Community Repository
```bash
#!/usr/bin/env bash
source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
# Enable community repo for more packages
add_community_repo
# Update and install
apk_update
apk_add postgresql postgresql-client
# Start service
rc-service postgresql start
```
### Development Environment
```bash
#!/usr/bin/env bash
source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
# Install build tools
setup_build_tools
setup_git
setup_nodejs "20"
# Install application
git clone https://example.com/app
cd app
npm install
```
## Best Practices
### ✅ DO
- Always use `apk add --no-cache` to keep images small
- Call `apk_update()` before installing packages
- Use community repository for more packages (`add_community_repo`)
- Handle apk locks gracefully with retry logic
- Use `$STD` variable for output control
- Check if tool already installed before reinstalling
### ❌ DON'T
- Use `apt-get` commands (Alpine doesn't have apt)
- Install packages without `--no-cache` flag
- Hardcode Alpine-specific paths
- Mix Alpine and Debian commands
- Forget to enable services with `rc-update`
- Use `systemctl` (Alpine has OpenRC, not systemd)
## Alpine Repository Configuration
### Default Repositories
Alpine comes with main repository enabled by default. Additional repos:
```bash
# Community repository (apk add php, go, rust, etc.)
add_community_repo
# Testing repository (bleeding edge packages)
add_testing_repo
```
### Repository Locations
```bash
/etc/apk/repositories # Main repo list
/etc/apk/keys/ # GPG keys for repos
/var/cache/apk/ # Package cache
```
## Package Size Optimization
Alpine is designed for small container images:
```bash
# DON'T: Leaves package cache (increases image size)
apk add nginx
# DO: Remove cache to reduce size
apk add --no-cache nginx
# Expected sizes:
# Alpine base: ~5MB
# Alpine + nginx: ~10-15MB
# Debian base: ~75MB
# Debian + nginx: ~90-95MB
```
## Service Management on Alpine
### Using OpenRC
```bash
# Start service immediately
rc-service nginx start
# Stop service
rc-service nginx stop
# Restart service
rc-service nginx restart
# Enable at boot
rc-update add nginx
# Disable at boot
rc-update del nginx
# List enabled services
rc-update show
```
## Troubleshooting
### "apk: lock is held by PID"
```bash
# Alpine apk database is locked (another process using apk)
# Wait a moment
sleep 5
apk_update
# Or manually:
rm /var/lib/apk/lock 2>/dev/null || true
apk update
```
### "Package not found"
```bash
# May be in community or testing repository
add_community_repo
apk_update
apk_add package-name
```
### "Repository not responding"
```bash
# Alpine repo may be slow or unreachable
# Try updating again with retry logic
apk_update # Built-in retry logic
# Or manually retry
sleep 10
apk update
```
### "Service fails to start"
```bash
# Check service status on Alpine
rc-service nginx status
# View logs
tail /var/log/nginx/error.log
# Verify configuration
nginx -t
```

## Common Usage Patterns
### Basic VM Setup with Cloud-Init
```bash
#!/usr/bin/env bash
source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
# Generate cloud-init configuration
cat > cloud-init.yaml <<EOF
#cloud-config
hostname: myvm
timezone: UTC
packages:
- curl
- wget
- git
users:
- name: ubuntu
ssh_authorized_keys:
- ssh-rsa AAAAB3...
sudo: ALL=(ALL) NOPASSWD:ALL
bootcmd:
- echo "VM initializing..."
runcmd:

## Execution Flow
```
Container Started
↓
source $FUNCTIONS_FILE_PATH
↓
setting_up_container() ← Display "Setting up container..."
↓
network_check() ← Verify internet connectivity
↓
update_os() ← Update package lists
↓
[Application-Specific Installation]
↓
motd_ssh() ← Configure SSH/MOTD
customize() ← Apply customizations
↓
cleanup_lxc() ← Final cleanup
↓
Installation Complete
```
## Common Usage Patterns
### Basic Container Setup
```bash
#!/usr/bin/env bash
source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
setting_up_container
network_check
update_os
# ... application installation ...
motd_ssh
customize
cleanup_lxc
```
### With Optional IPv6
```bash
#!/usr/bin/env bash
source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
setting_up_container
verb_ip6 # Enable IPv6
network_check
update_os
# ... installation ...
motd_ssh
customize
cleanup_lxc
```
### With Custom Update Script
```bash
#!/usr/bin/env bash
source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
setting_up_container
network_check
update_os
# ... installation ...
# Register update function
function update_script() {
# Update logic here
}
export -f update_script
motd_ssh
customize
cleanup_lxc
```
## Best Practices
### ✅ DO
- Call `setting_up_container()` at the start
- Check `network_check()` output before main installation
- Use `$STD` variable for silent operations
- Call `cleanup_lxc()` at the very end
- Test network connectivity before critical operations
### ❌ DON'T
- Skip network verification
- Assume internet is available
- Hardcode container paths
- Use `echo` instead of `msg_*` functions
- Forget to call cleanup at the end
## Environment Variables
### Available Variables
- `$FUNCTIONS_FILE_PATH` - Path to core functions (set by build.func)
- `$CTID` - Container ID number
- `$NSAPP` - Normalized application name (lowercase)
- `$APP` - Application display name
- `$STD` - Output suppression (`silent` or empty)
- `$VERBOSE` - Verbose output mode (`yes` or `no`)
### Setting Container Variables
```bash
CONTAINER_TIMEZONE="UTC"
CONTAINER_HOSTNAME="myapp-container"
CONTAINER_FQDN="myapp.example.com"
```
## Troubleshooting
### "Network check failed"
```bash
# Container may not have internet access
# Check:
ping 8.8.8.8 # External connectivity
nslookup example.com # DNS resolution
ip route show # Routing table
```
### "Package update failed"
```bash
# APT may be locked by another process
ps aux | grep apt # Check for running apt
# Or wait for existing apt to finish
sleep 30
update_os
```
### "Cannot source functions"
```bash
# $FUNCTIONS_FILE_PATH may not be set
# This variable is set by build.func before running install script
# If missing, the install script was not called properly
```

```
tools.func
├── Uses: core.func (messaging, colors)
├── Uses: error_handler.func (exit codes, trapping)
├── Uses: install.func (network_check, update_os)
│
└── Used by: All install/*.sh scripts
├── For: Package installation
├── For: Tool setup
└── For: Repository management
```
## Troubleshooting
### "Package manager is locked"
```bash
# Wait for apt lock to release
sleep 10
pkg_update
```
### "GPG key not found"
```bash
# Repository setup will handle this automatically
# If manual fix needed:
cleanup_repo_metadata
setup_deb822_repo ...
```
### "Tool installation failed"
```bash
# Enable verbose output
export var_verbose="yes"
setup_nodejs "20"
```
## Contributing
When adding new tool installation functions:
1. Follow the `setup_TOOLNAME()` naming convention
2. Accept version as first parameter
3. Check if tool already installed
4. Use `$STD` for output suppression
5. Set version file: `/opt/TOOLNAME_version.txt`

# tools.func Integration Guide
How tools.func integrates with other components and provides package/tool services to the ProxmoxVED ecosystem.
## Component Relationships
### tools.func in the Installation Pipeline
```
ct/AppName.sh (host)
│
├─ Calls build.func
│
└─ Creates Container
│
▼
install/appname-install.sh (container)
│
├─ Sources: core.func (colors, messaging)
├─ Sources: error_handler.func (error handling)
├─ Sources: install.func (container setup)
│
└─ ★ Sources: tools.func ★
│
├─ pkg_update()
├─ pkg_install()
├─ setup_nodejs()
├─ setup_php()
├─ setup_mariadb()
└─ ... 30+ functions
```
### Integration with core.func
**tools.func uses core.func for**:
- `msg_info()` - Display progress messages
- `msg_ok()` - Display success messages
- `msg_error()` - Display error messages
- `msg_warn()` - Display warnings
- Color codes (GN, RD, YW, BL) for formatted output
- `$STD` variable - Output suppression control
**Example**:
```bash
# tools.func internally calls:
msg_info "Installing Node.js" # Uses core.func
setup_nodejs "20" # Setup happens
msg_ok "Node.js installed" # Uses core.func
```
### Integration with error_handler.func
**tools.func uses error_handler.func for**:
- Exit code mapping to error descriptions
- Automatic error trapping (catch_errors)
- Signal handlers (SIGINT, SIGTERM, EXIT)
- Structured error reporting
**Example**:
```bash
# If setup_nodejs fails, error_handler catches it:
catch_errors # Calls from error_handler.func
setup_nodejs "20" # If this exits non-zero
# error_handler logs and traps it
```
### Integration with install.func
**tools.func coordinates with install.func for**:
- Initial OS updates (install.func) → then tools (tools.func)
- Network verification before tool installation
- Package manager state validation
- Cleanup procedures after tool setup
**Sequence**:
```bash
setting_up_container() # From install.func
network_check() # From install.func
update_os() # From install.func
pkg_update # From tools.func
setup_nodejs() # From tools.func
motd_ssh() # From install.func
customize() # From install.func
cleanup_lxc() # From install.func
```
---
## Integration with alpine-tools.func (Alpine Containers)
### When to Use tools.func vs alpine-tools.func
| Feature | tools.func (Debian) | alpine-tools.func (Alpine) |
|---------|:---:|:---:|
| Package Manager | apt-get | apk |
| Installation Scripts | install/*.sh | install/*-alpine.sh |
| Tool Setup | `setup_nodejs()` (apt) | `setup_nodejs()` (apk) |
| Repository | `setup_deb822_repo()` | `add_community_repo()` |
| Services | systemctl | rc-service |
### Automatic Selection
Installation scripts detect OS and source appropriate functions:
```bash
# install/myapp-install.sh
if grep -qi 'alpine' /etc/os-release; then
# Alpine detected - uses alpine-tools.func
apk_update
apk_add package
else
# Debian detected - uses tools.func
pkg_update
pkg_install package
fi
```
---
## Dependencies Management

## Configuration Management
### Environment Variables Used by tools.func
```bash
# Output control
STD="silent" # Suppress apt/apk output
VERBOSE="yes" # Show all output
# Package management
DEBIAN_FRONTEND="noninteractive"
# Tool versions (optional)
NODEJS_VERSION="20"
PHP_VERSION="8.3"
POSTGRES_VERSION="16"
```
### Tools Configuration Files Created
```
/opt/
├─ nodejs_version.txt # Node.js version
├─ php_version.txt # PHP version
├─ mariadb_version.txt # MariaDB version
├─ postgresql_version.txt # PostgreSQL version
├─ docker_version.txt # Docker version
└─ [TOOL]_version.txt # For all installed tools
/etc/apt/sources.list.d/
├─ nodejs.sources # Node.js repo (deb822)
├─ docker.sources # Docker repo (deb822)
└─ [name].sources # Other repos (deb822)
```
---
## Error Handling Integration
### Exit Codes from tools.func
| Code | Meaning | Handled By |
|------|:---:|:---:|
| 0 | Success | Normal flow |
| 1 | Package installation failed | error_handler.func |
| 100-101 | APT error | error_handler.func |
| 127 | Command not found | error_handler.func |
### Automatic Cleanup on Failure
```bash
# If any step fails in install script:
catch_errors
pkg_update # Fail here?
setup_nodejs # Doesn't get here
# error_handler automatically:
├─ Logs error
├─ Captures exit code
├─ Calls cleanup_lxc()
└─ Exits with proper code
```
---
## Integration with build.func
### Variable Flow
```
ct/app.sh
│
├─ var_cpu="2"
├─ var_ram="2048"
├─ var_disk="10"
│
└─ Calls: build_container() [build.func]
│
└─ Creates container
│
└─ Calls: install/app-install.sh
│
└─ Uses: tools.func for installation
```
### Resource Considerations
tools.func respects container resource limits:
- Large package installations respect allocated RAM
- Database setups use allocated disk space
- Build tools (gcc, make) stay within CPU allocation
---
## Version Management
### How tools.func Tracks Versions
Each tool installation creates a version file:
```bash
# setup_nodejs() creates:
echo "20.10.5" > /opt/nodejs_version.txt
# Used by update scripts:
CURRENT=$(cat /opt/nodejs_version.txt)
LATEST=$(curl ... # fetch latest)
if [[ "$LATEST" != "$CURRENT" ]]; then
# Update needed
fi
```
### Integration with Update Functions
```bash
# In ct/app.sh:
function update_script() {
# Check Node version
RELEASE=$(curl ... | jq '.version')
CURRENT=$(cat /opt/nodejs_version.txt)
if [[ "$RELEASE" != "$CURRENT" ]]; then
# Use tools.func to upgrade
setup_nodejs "$RELEASE"
fi
}
```
---
## Best Practices for Integration
### ✅ DO
1. **Call functions in proper order**
```bash
pkg_update
setup_tool "version"
```
2. **Use $STD for production**
```bash
export STD="silent"
pkg_install curl wget
```
3. **Check for existing installations**
```bash
command -v nodejs >/dev/null || setup_nodejs "20"
```
4. **Coordinate with install.func**
```bash
setting_up_container
update_os # From install.func
setup_nodejs # From tools.func
motd_ssh # Back to install.func
```
### ❌ DON'T
1. **Don't skip pkg_update**
```bash
# Bad - may fail due to stale cache
pkg_install curl
```
2. **Don't hardcode versions**
```bash
# Bad
apt-get install nodejs=20.x
# Good
setup_nodejs "20"
```
3. **Don't mix package managers**
```bash
# Bad
apt-get install curl
apk add wget
```
4. **Don't ignore errors**
```bash
# Bad
setup_docker || true
# Good
if ! setup_docker; then
msg_error "Docker failed"
exit 1
fi
```

## Troubleshooting Integration Issues
### "Package installation fails"
- Check: `pkg_update` was called first
- Check: Package name is correct for OS
- Solution: Manually verify in container
### "Tool not accessible after installation"
- Check: Tool added to PATH
- Check: Version file created
- Solution: `which toolname` to verify
### "Repository conflicts"
- Check: No duplicate repositories
- Solution: `cleanup_repo_metadata()` before adding
### "Alpine-specific errors when using Debian tools"
- Problem: Using tools.func functions on Alpine
- Solution: Use alpine-tools.func instead

## Tips & Best Practices
### ✅ DO
```bash
# Use $STD for silent operations
$STD apt-get install curl
# Use pkg_update before installing
pkg_update
pkg_install package-name
# Chain multiple tools together
setup_nodejs "20"
setup_php "8.3"
setup_mariadb "11"
# Check command success
if ! setup_docker; then
msg_error "Docker installation failed"
exit 1
fi
```
### ❌ DON'T
```bash
# Don't hardcode commands
apt-get install curl # Bad
# Don't skip updates
pkg_install package # May fail if cache stale
# Don't ignore errors
setup_nodejs || true # Silences errors silently
# Don't mix package managers
apt-get install curl
apk add wget # Don't mix!
```
