# Ollama Deployment Guide
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
This guide covers the deployment and management of Ollama on the grey-area server in your home lab. Ollama provides local Large Language Model (LLM) hosting with an OpenAI-compatible API.
|
||||||
|
|
||||||
|
## Quick Start
|
||||||
|
|
||||||
|
### 1. Deploy the Service
|
||||||
|
|
||||||
|
The Ollama service is already configured in your NixOS configuration. To deploy:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Navigate to your home lab directory
|
||||||
|
cd /home/geir/Home-lab
|
||||||
|
|
||||||
|
# Build and switch to the new configuration
|
||||||
|
sudo nixos-rebuild switch --flake .#grey-area
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Verify Installation
|
||||||
|
|
||||||
|
After deployment, verify the service is running:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Check service status
|
||||||
|
systemctl status ollama
|
||||||
|
|
||||||
|
# Check if API is responding
|
||||||
|
curl http://localhost:11434/api/tags
|
||||||
|
|
||||||
|
# Run the test script
|
||||||
|
sudo /etc/ollama-test.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Monitor Model Downloads
|
||||||
|
|
||||||
|
The service will automatically download the configured models on first start:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Monitor the model download process
|
||||||
|
journalctl -u ollama-model-download -f
|
||||||
|
|
||||||
|
# Check downloaded models
|
||||||
|
ollama list

|
||||||
|
```
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Common Issues
|
||||||
|
|
||||||
|
#### Service Won't Start
|
||||||
|
```bash
|
||||||
|
# Check for configuration errors
|
||||||
|
journalctl -u ollama --no-pager
|
||||||
|
|
||||||
|
# Verify disk space (models are large)
|
||||||
|
df -h /var/lib/ollama
|
||||||
|
|
||||||
|
# Check memory availability
|
||||||
|
free -h
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Models Not Downloading
|
||||||
|
```bash
|
||||||
|
# Check model download service
|
||||||
|
systemctl status ollama-model-download
|
||||||
|
journalctl -u ollama-model-download
|
||||||
|
|
||||||
|
# Manually download models
|
||||||
|
sudo -u ollama ollama pull llama3.3:8b
|
||||||
|
```
|
||||||
|
|
||||||
|
#### API Not Responding
|
||||||
|
```bash
|
||||||
|
# Check if service is listening
|
||||||
|
ss -tlnp | grep 11434
|
||||||
|
|
||||||
|
# Test API manually
|
||||||
|
curl -v http://localhost:11434/api/tags
|
||||||
|
|
||||||
|
# Check firewall (if accessing externally)
|
||||||
|
sudo iptables -L | grep 11434
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Out of Memory Errors
|
||||||
|
```bash
|
||||||
|
# Check current memory usage
|
||||||
|
cat /sys/fs/cgroup/system.slice/ollama.service/memory.current
|
||||||
|
|
||||||
|
# Reduce resource limits in configuration
|
||||||
|
# Edit grey-area/services/ollama.nix and reduce maxMemory
|
||||||
|
```
|
||||||
|
|
||||||
|
### Performance Optimization
|
||||||
|
|
||||||
|
#### For Better Performance
|
||||||
|
1. **Add more RAM**: Models perform better with more available memory
|
||||||
|
2. **Use SSD storage**: Faster model loading from NVMe/SSD
|
||||||
|
3. **Enable GPU acceleration**: If you have compatible GPU hardware
|
||||||
|
4. **Adjust context length**: Reduce OLLAMA_CONTEXT_LENGTH for faster responses
|
||||||
|
|
||||||
|
#### For Lower Resource Usage
|
||||||
|
1. **Use smaller models**: Consider 2B or 3B parameter models
|
||||||
|
2. **Reduce parallel requests**: Set OLLAMA_NUM_PARALLEL to 1
|
||||||
|
3. **Limit memory**: Reduce maxMemory setting
|
||||||
|
4. **Use quantized models**: Many models have Q4_0, Q5_0 variants
|
||||||
|
|
||||||
|
## Security Considerations
|
||||||
|
|
||||||
|
### Current Security Posture
|
||||||
|
- Service runs as dedicated `ollama` user
|
||||||
|
- Bound to localhost only (no external access)
|
||||||
|
- Systemd security hardening enabled
|
||||||
|
- No authentication (intended for local use)
|
||||||
|
|
||||||
|
### Enabling External Access
|
||||||
|
|
||||||
|
If you need external access, use a reverse proxy instead of opening the port directly:
|
||||||
|
|
||||||
|
```nix
|
||||||
|
# Add to grey-area configuration
|
||||||
|
services.nginx = {
|
||||||
|
enable = true;
|
||||||
|
virtualHosts."ollama.grey-area.lan" = {
|
||||||
|
listen = [{ addr = "0.0.0.0"; port = 8080; }];
|
||||||
|
locations."/" = {
|
||||||
|
proxyPass = "http://127.0.0.1:11434";
|
||||||
|
extraConfig = ''
|
||||||
|
# Add authentication here if needed
|
||||||
|
# auth_basic "Ollama API";
|
||||||
|
# auth_basic_user_file /etc/nginx/ollama.htpasswd;
|
||||||
|
'';
|
||||||
|
};
|
||||||
|
};
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
## Integration Examples
|
||||||
|
|
||||||
|
### With Forgejo
|
||||||
|
Create a webhook or git hook to review code:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/bin/bash
|
||||||
|
# .git/hooks/pre-commit
|
||||||
|
git diff --cached | ollama run codellama:7b "Review this code for issues:"
|
||||||
|
```
|
||||||
|
|
||||||
|
### With Development Workflow
|
||||||
|
```bash
|
||||||
|
# Add to shell aliases
|
||||||
|
alias code-review='git diff | ollama run codellama:7b "Review this code:"'
|
||||||
|
alias explain-code='ollama run codellama:7b "Explain this code:"'
|
||||||
|
alias write-docs='ollama run llama3.3:8b "Write documentation for:"'
|
||||||
|
```
|
||||||
|
|
||||||
|
### With Other Services
|
||||||
|
```bash
|
||||||
|
# Generate descriptions for Jellyfin media
|
||||||
|
find /media -name "*.mkv" | while read file; do
|
||||||
|
echo "Generating description for $(basename "$file")"
|
||||||
|
echo "$(basename "$file" .mkv)" | ollama run llama3.3:8b "Create a brief description for this movie/show:"
|
||||||
|
done
|
||||||
|
```
|
||||||
|
|
||||||
|
## Backup and Maintenance
|
||||||
|
|
||||||
|
### Automatic Backups
|
||||||
|
- Configuration backup: Included in NixOS configuration
|
||||||
|
- Model manifests: Backed up weekly to `/var/backup/ollama`
|
||||||
|
- Model files: Not backed up (re-downloadable)
|
||||||
|
|
||||||
|
### Manual Backup
|
||||||
|
```bash
|
||||||
|
# Backup custom models or fine-tuned models
|
||||||
|
sudo tar -czf ollama-custom-$(date +%Y%m%d).tar.gz /var/lib/ollama/
|
||||||
|
|
||||||
|
# Backup to remote location
|
||||||
|
sudo rsync -av /var/lib/ollama/ backup-server:/backups/ollama/
|
||||||
|
```
|
||||||
|
|
||||||
|
### Updates
|
||||||
|
```bash
|
||||||
|
# Update Ollama package
|
||||||
|
sudo nixos-rebuild switch --flake .#grey-area
|
||||||
|
|
||||||
|
# Update models (if new versions available)
|
||||||
|
ollama pull llama3.3:8b
|
||||||
|
ollama pull codellama:7b
|
||||||
|
ollama pull mistral:7b
|
||||||
|
```
|
||||||
|
|
||||||
|
## Future Enhancements
|
||||||
|
|
||||||
|
### Potential Additions
|
||||||
|
1. **Web UI**: Deploy Open WebUI for browser-based interaction
|
||||||
|
2. **Model Management**: Automated model updates and cleanup
|
||||||
|
3. **Multi-GPU**: Support for multiple GPU acceleration
|
||||||
|
4. **Custom Models**: Fine-tuning setup for domain-specific models
|
||||||
|
5. **Metrics**: Prometheus metrics export for monitoring
|
||||||
|
6. **Load Balancing**: Multiple Ollama instances for high availability
|
||||||
|
|
||||||
|

2. **User/Group Setup**: Dedicated `ollama` user and group created for security
|
||||||
|
3. **Model Downloads**: Three AI models will be automatically downloaded:
|
||||||
|
- **llama3.3:8b** (~4.7GB) - General purpose model
|
||||||
|
- **codellama:7b** (~3.8GB) - Code-focused model
|
||||||
|
- **mistral:7b** (~4.1GB) - Fast inference model
|
||||||
|
4. **Directory Setup**: `/var/lib/ollama` created for model storage
|
||||||
|
5. **Security Hardening**: Service runs with restricted permissions
|
||||||
|
6. **Resource Limits**: Memory limited to 12GB, CPU to 75%
|
||||||
|
|
||||||
|
## Post-Deployment Verification
|
||||||
|
|
||||||
|
After deployment, verify everything is working:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Check service status
|
||||||
|
systemctl status ollama
|
||||||
|
|
||||||
|
# Test API connectivity
|
||||||
|
curl http://localhost:11434/api/tags
|
||||||
|
|
||||||
|
# Use the CLI tool
|
||||||
|
/home/geir/Home-lab/scripts/ollama-cli.sh status
|
||||||
|
|
||||||
|
# Run comprehensive monitoring
|
||||||
|
/home/geir/Home-lab/scripts/monitor-ollama.sh --test-inference
|
||||||
|
```
|
||||||
|
|
||||||
|
## Storage Requirements
|
||||||
|
|
||||||
|
The initial setup will download approximately **12.6GB** of model data:
|
||||||
|
- llama3.3:8b: ~4.7GB
|
||||||
|
- codellama:7b: ~3.8GB
|
||||||
|
- mistral:7b: ~4.1GB
|
||||||
|
|
||||||
|
Ensure grey-area has sufficient storage space.
|
||||||
|
|
||||||
|
## Usage Examples
|
||||||
|
|
||||||
|
Once deployed, you can use Ollama for:
|
||||||
|
|
||||||
|
### Interactive Chat
|
||||||
|
```bash
|
||||||
|
# Start interactive session with a model
|
||||||
|
ollama run llama3.3:8b
|
||||||
|
|
||||||
|
# Code assistance
|
||||||
|
ollama run codellama:7b "Review this function for security issues"
|
||||||
|
```
|
||||||
|
|
||||||
|
### API Usage
|
||||||
|
```bash
|
||||||
|
# Generate text via API
|
||||||
|
curl -X POST http://localhost:11434/api/generate \
|
||||||
|
-H "Content-Type: application/json" \
|
||||||
|
-d '{"model": "llama3.3:8b", "prompt": "Explain NixOS modules", "stream": false}'
|
||||||
|
|
||||||
|
# OpenAI-compatible API
|
||||||
|
curl http://localhost:11434/v1/chat/completions \
|
||||||
|
-H "Content-Type: application/json" \
|
||||||
|
-d '{"model": "mistral:7b", "messages": [{"role": "user", "content": "Hello!"}]}'
|
||||||
|
```
|
||||||
|
|
||||||
|
### CLI Tool
|
||||||
|
```bash
|
||||||
|
# Using the provided CLI tool
|
||||||
|
ollama-cli.sh models # List installed models
|
||||||
|
ollama-cli.sh chat mistral:7b # Start chat session
|
||||||
|
ollama-cli.sh test # Run functionality tests
|
||||||
|
ollama-cli.sh pull phi4:14b # Install additional models
|
||||||
|
```
|
||||||
|
|
||||||
|
## Security Configuration
|
||||||
|
|
||||||
|
The deployment uses secure defaults:
|
||||||
|
- **Network Binding**: localhost only (127.0.0.1:11434)
|
||||||
|
- **User Isolation**: Dedicated `ollama` user with minimal permissions
|
||||||
|
- **Systemd Hardening**: Extensive security restrictions applied
|
||||||
|
- **No External Access**: Firewall closed by default
|
||||||
|
|
||||||
|
To enable external access, consider using a reverse proxy (examples provided in documentation).
|
||||||
|
|
||||||
|
## Resource Management
|
||||||
|
|
||||||
|
The service includes resource limits to prevent impact on other grey-area services:
|
||||||
|
- **Memory Limit**: 12GB maximum
|
||||||
|
- **CPU Limit**: 75% maximum
|
||||||
|
- **Process Isolation**: Separate user and group
|
||||||
|
- **File System Restrictions**: Limited write access
|
||||||
|
|
||||||
|
## Monitoring and Maintenance
|
||||||
|
|
||||||
|
The deployment includes:
|
||||||
|
- **Health Checks**: Automated service health monitoring
|
||||||
|
- **Backup System**: Configuration and custom model backup
|
||||||
|
- **Log Management**: Structured logging with rotation
|
||||||
|
- **Performance Monitoring**: Resource usage tracking
|
||||||
|
|
||||||
|
## Next Steps
|
||||||
|
|
||||||
|
1. **Deploy**: Run the nixos-rebuild command above
|
||||||
|
2. **Verify**: Check service status and API connectivity
|
||||||
|
3. **Test**: Try the CLI tools and API examples
|
||||||
|
4. **Integrate**: Use the integration examples for your development workflow
|
||||||
|
5. **Monitor**: Set up regular monitoring using the provided tools
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
If you encounter issues:
|
||||||
|
|
||||||
|
1. **Check Service Status**: `systemctl status ollama`
|
||||||
|
2. **View Logs**: `journalctl -u ollama -f`
|
||||||
|
3. **Monitor Downloads**: `journalctl -u ollama-model-download -f`
|
||||||
|
4. **Run Diagnostics**: `/home/geir/Home-lab/scripts/monitor-ollama.sh`
|
||||||
|
5. **Check Storage**: `df -h /var/lib/ollama`
|
||||||
|
|
||||||
|
## Future Enhancements
|
||||||
|
|
||||||
|
Consider these potential improvements:
|
||||||
|
- **GPU Acceleration**: Enable if you add a compatible GPU to grey-area
|
||||||
|
- **Web Interface**: Deploy Open WebUI for browser-based interaction
|
||||||
|
- **External Access**: Configure reverse proxy for remote access
|
||||||
|
- **Additional Models**: Install specialized models for specific tasks
|

# Ollama Integration Examples
|
||||||
|
|
||||||
|
This document provides practical examples of integrating Ollama into your home lab development workflow.
|
||||||
|
|
||||||
|
## Development Workflow Integration
|
||||||
|
|
||||||
|
### 1. Git Hooks for Code Review
|
||||||
|
|
||||||
|
Create a pre-commit hook that uses Ollama for code review:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/usr/bin/env bash
|
||||||
|
# .git/hooks/pre-commit
|
||||||
|
|
||||||
|
# Check if ollama is available
|
||||||
|
if ! command -v ollama &> /dev/null; then
|
||||||
|
echo "Ollama not available, skipping AI code review"
|
||||||
|
exit 0
|
||||||
|
fi
|
||||||
|
|
||||||
|
# Get the diff of staged changes
|
||||||
|
staged_diff=$(git diff --cached)
|
||||||
|
|
||||||
|
if [[ -n "$staged_diff" ]]; then
|
||||||
|
echo "🤖 Running AI code review..."
|
||||||
|
|
||||||
|
# Use CodeLlama for code review
|
||||||
|
review_result=$(echo "$staged_diff" | ollama run codellama:7b "Review this code diff for potential issues, security concerns, and improvements. Be concise:")
|
||||||
|
|
||||||
|
if [[ -n "$review_result" ]]; then
|
||||||
|
echo "AI Code Review Results:"
|
||||||
|
echo "======================="
|
||||||
|
echo "$review_result"
|
||||||
|
echo
|
||||||
|
|
||||||
|
read -p "Continue with commit? (y/N): " -n 1 -r
|
||||||
|
echo
|
||||||
|
if [[ ! $REPLY =~ ^[Yy]$ ]]; then
|
||||||
|
echo "Commit aborted by user"
|
||||||
|
exit 1
|
||||||
|
fi
|
||||||
|
fi
|
||||||
|
fi
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Documentation Generation
|
||||||
|
|
||||||
|
Create a script to generate documentation for your NixOS modules:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/usr/bin/env bash
|
||||||
|
# scripts/generate-docs.sh
|
||||||
|
|
||||||
|
module_file="$1"
|
||||||
|
if [[ ! -f "$module_file" ]]; then
|
||||||
|
echo "Usage: $0 <nix-module-file>"
|
||||||
|
exit 1
|
||||||
|
fi
|
||||||
|
|
||||||
|
echo "Generating documentation for $module_file..."
|
||||||
|
|
||||||
|
# Read the module content
|
||||||
|
module_content=$(cat "$module_file")
|
||||||
|
|
||||||
|
# Generate documentation using Ollama
|
||||||
|
documentation=$(echo "$module_content" | ollama run llama3.3:8b "Generate comprehensive documentation for this NixOS module. Include:
|
||||||
|
1. Overview and purpose
|
||||||
|
2. Configuration options
|
||||||
|
3. Usage examples
|
||||||
|
4. Security considerations
|
||||||
|
5. Troubleshooting tips
|
||||||
|
|
||||||
|
Module content:")
|
||||||
|
|
||||||
|
# Save to documentation file
|
||||||
|
doc_file="${module_file%.nix}.md"
|
||||||
|
echo "$documentation" > "$doc_file"
|
||||||
|
|
||||||
|
echo "Documentation saved to: $doc_file"
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Configuration Analysis
|
||||||
|
|
||||||
|
Analyze your NixOS configurations for best practices:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/usr/bin/env bash
|
||||||
|
# scripts/analyze-config.sh
|
||||||
|
|
||||||
|
config_file="$1"
|
||||||
|
if [[ ! -f "$config_file" ]]; then
|
||||||
|
echo "Usage: $0 <configuration.nix>"
|
||||||
|
exit 1
|
||||||
|
fi
|
||||||
|
|
||||||
|
echo "Analyzing NixOS configuration: $config_file"
|
||||||
|
|
||||||
|
config_content=$(cat "$config_file")
|
||||||
|
|
||||||
|
analysis=$(echo "$config_content" | ollama run mistral:7b "Analyze this NixOS configuration for:
|
||||||
|
1. Security best practices
|
||||||
|
2. Performance optimizations
|
||||||
|
3. Potential issues
|
||||||
|
4. Recommended improvements
|
||||||
|
5. Missing common configurations
|
||||||
|
|
||||||
|
Configuration:")
|
||||||
|
|
||||||
|
echo "Configuration Analysis"
|
||||||
|
echo "====================="
|
||||||
|
echo "$analysis"
|
||||||
|
```
|
||||||
|
|
||||||
|
## Service Integration Examples
|
||||||
|
|
||||||
|
### 1. Forgejo Integration
|
||||||
|
|
||||||
|
Create webhooks in Forgejo that trigger AI-powered code reviews:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/usr/bin/env bash
|
||||||
|
# scripts/forgejo-webhook-handler.sh
|
||||||
|
|
||||||
|
# Webhook handler for Forgejo push events
|
||||||
|
# Place this in your web server and configure Forgejo to call it
|
||||||
|
|
||||||
|
payload=$(cat)
|
||||||
|
branch=$(echo "$payload" | jq -r '.ref | split("/") | last')
|
||||||
|
repo=$(echo "$payload" | jq -r '.repository.name')
|
||||||
|
|
||||||
|
if [[ "$branch" == "main" || "$branch" == "master" ]]; then
|
||||||
|
echo "Analyzing push to $repo:$branch"
|
||||||
|
|
||||||
|
# Get the commit diff
|
||||||
|
commit_sha=$(echo "$payload" | jq -r '.after')
|
||||||
|
|
||||||
|
# Fetch the diff (you'd need to implement this based on your Forgejo API)
|
||||||
|
diff_content=$(get_commit_diff "$repo" "$commit_sha")
|
||||||
|
|
||||||
|
# Analyze with Ollama
|
||||||
|
analysis=$(echo "$diff_content" | ollama run codellama:7b "Analyze this commit for potential issues:")
|
||||||
|
|
||||||
|
# Post results back to Forgejo (implement based on your needs)
|
||||||
|
post_comment_to_commit "$repo" "$commit_sha" "$analysis"
|
||||||
|
fi
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. System Monitoring Integration

```bash
|
||||||
|
#!/usr/bin/env bash
|
||||||
|
# scripts/ai-log-analyzer.sh
|
||||||
|
|
||||||
|
service="$1"
|
||||||
|
if [[ -z "$service" ]]; then
|
||||||
|
echo "Usage: $0 <service-name>"
|
||||||
|
exit 1
|
||||||
|
fi
|
||||||
|
|
||||||
|
echo "Analyzing logs for service: $service"
|
||||||
|
|
||||||
|
# Get recent logs
|
||||||
|
logs=$(journalctl -u "$service" --since "1 hour ago" --no-pager)
|
||||||
|
|
||||||
|
if [[ -n "$logs" ]]; then
|
||||||
|
analysis=$(echo "$logs" | ollama run llama3.3:8b "Analyze these system logs for:
|

|
||||||
|
|
||||||
|
echo "AI Log Analysis for $service"
|
||||||
|
echo "============================"
|
||||||
|
echo "$analysis"
|
||||||
|
else
|
||||||
|
echo "No recent logs found for $service"
|
||||||
|
fi
|

|
|
||||||
|
## Home Assistant Integration (if deployed)
|
||||||
|
|
||||||
|
### 1. Smart Home Automation
|
||||||
|
|
||||||
|
If you deploy Home Assistant on grey-area, integrate it with Ollama:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# configuration.yaml for Home Assistant
|
||||||
|
automation:
|
||||||
|
- alias: "AI System Health Report"
|
||||||
|
trigger:
|
||||||
|
platform: time
|
||||||
|
at: "09:00:00"
|
||||||
|
action:
|
||||||
|
- service: shell_command.generate_health_report
|
||||||
|
- service: notify.telegram # or your preferred notification service
|
||||||
|
data:
|
||||||
|
title: "Daily System Health Report"
|
||||||
|
message: "{{ states('sensor.ai_health_report') }}"
|
||||||
|
|
||||||
|
shell_command:
|
||||||
|
generate_health_report: "/home/geir/Home-lab/scripts/ai-health-report.sh"
|
||||||
|
```
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/usr/bin/env bash
|
||||||
|
# scripts/ai-health-report.sh
|
||||||
|
|
||||||
|
# Collect system metrics
|
||||||
|
uptime_info=$(uptime)
|
||||||
|
disk_usage=$(df -h / | tail -1)
|
||||||
|
memory_usage=$(free -h | grep Mem)
|
||||||
|
load_avg=$(cat /proc/loadavg)
|
||||||
|
|
||||||
|
# Service statuses
|
||||||
|
ollama_status=$(systemctl is-active ollama)
|
||||||
|
jellyfin_status=$(systemctl is-active jellyfin)
|
||||||
|
forgejo_status=$(systemctl is-active forgejo)
|
||||||
|
|
||||||
|
# Generate AI summary
|
||||||
|
report=$(cat << EOF | ollama run mistral:7b "Summarize this system health data and provide recommendations:"
|
||||||
|

- Ollama: $ollama_status
|
||||||
|
- Jellyfin: $jellyfin_status
|
||||||
|
- Forgejo: $forgejo_status
|
||||||
|
EOF
|
||||||
|
)
|
||||||
|
|
||||||
|
echo "$report" > /tmp/health_report.txt
|
||||||
|
echo "$report"
|
||||||
|
```
|
||||||
|
|
||||||
|
## Development Tools Integration
|
||||||
|
|
||||||
|
### 1. VS Code/Editor Integration
|
||||||
|
|
||||||
|
Create editor snippets that use Ollama for code generation:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/usr/bin/env bash
|
||||||
|
# scripts/code-assistant.sh
|
||||||
|
|
||||||
|
action="$1"
|
||||||
|
input_file="$2"
|
||||||
|
|
||||||
|
case "$action" in
|
||||||
|
"explain")
|
||||||
|
code_content=$(cat "$input_file")
|
||||||
|
ollama run codellama:7b "Explain this code in detail:" <<< "$code_content"
|
||||||
|
;;
|
||||||
|
"optimize")
|
||||||
|
code_content=$(cat "$input_file")
|
||||||
|
ollama run codellama:7b "Suggest optimizations for this code:" <<< "$code_content"
|
||||||
|
;;
|
||||||
|
"test")
|
||||||
|
code_content=$(cat "$input_file")
|
||||||
|
ollama run codellama:7b "Generate unit tests for this code:" <<< "$code_content"
|
||||||
|
;;
|
||||||
|
"document")
|
||||||
|
code_content=$(cat "$input_file")
|
||||||
|
ollama run llama3.3:8b "Generate documentation comments for this code:" <<< "$code_content"
|
||||||
|
;;
|
||||||
|
*)
|
||||||
|
echo "Usage: $0 {explain|optimize|test|document} <file>"
|
||||||
|
exit 1
|
||||||
|
;;
|
||||||
|
esac
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Terminal Integration
|
||||||
|
|
||||||
|
Add shell functions for quick AI assistance:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Add to your .zshrc or .bashrc
|
||||||
|
|
||||||
|
# AI-powered command explanation
|
||||||
|
explain() {
|
||||||
|
if [[ -z "$1" ]]; then
|
||||||
|
echo "Usage: explain <command>"
|
||||||
|
return 1
|
||||||
|
fi
|
||||||
|
|
||||||
|
echo "Explaining command: $*"
|
||||||
|
echo "$*" | ollama run llama3.3:8b "Explain this command in detail, including options and use cases:"
|
||||||
|
}
|
||||||
|
|
||||||
|
# AI-powered error debugging
|
||||||
|
debug() {
|
||||||
|
if [[ -z "$1" ]]; then
|
||||||
|
echo "Usage: debug <error_message>"
|
||||||
|
return 1
|
||||||
|
fi
|
||||||
|
|
||||||
|
echo "Debugging: $*"
|
||||||
|
echo "$*" | ollama run llama3.3:8b "Help debug this error message and suggest solutions:"
|
||||||
|
}
|
||||||
|
|
||||||
|
# Quick code review
|
||||||
|
review() {
|
||||||
|
if [[ -z "$1" ]]; then
|
||||||
|
echo "Usage: review <file>"
|
||||||
|
return 1
|
||||||
|
fi
|
||||||
|
|
||||||
|
if [[ ! -f "$1" ]]; then
|
||||||
|
echo "File not found: $1"
|
||||||
|
return 1
|
||||||
|
fi
|
||||||
|
|
||||||
|
echo "Reviewing file: $1"
|
||||||
|
cat "$1" | ollama run codellama:7b "Review this code for potential issues and improvements:"
|
||||||
|
}
|
||||||
|
|
||||||
|
# Generate commit messages
|
||||||
|
gitmsg() {
|
||||||
|
diff_content=$(git diff --cached)
|

## API Integration Examples
|
||||||
|
|
||||||
|
### 1. Monitoring Dashboard
|
||||||
|
|
||||||
|
Create a simple web dashboard that shows AI-powered insights:
|
||||||
|
|
||||||
|
```python
|
||||||
|
#!/usr/bin/env python3
|
||||||
|
# scripts/ai-dashboard.py
|
||||||
|
|
||||||
|
import requests
|
||||||
|
import json
|
||||||
|
from datetime import datetime
|
||||||
|
import subprocess
|
||||||
|
|
||||||
|
OLLAMA_URL = "http://localhost:11434"
|
||||||
|
|
||||||
|
def get_system_metrics():
|
||||||
|
"""Collect system metrics"""
|
||||||
|
uptime = subprocess.check_output(['uptime'], text=True).strip()
|
||||||
|
df = subprocess.check_output(['df', '-h', '/'], text=True).split('\n')[1]
|
||||||
|
memory = subprocess.check_output(['free', '-h'], text=True).split('\n')[1]
|
||||||
|
|
||||||
|
return {
|
||||||
|
'timestamp': datetime.now().isoformat(),
|
||||||
|
'uptime': uptime,
|
||||||
|
'disk': df,
|
||||||
|
'memory': memory
|
||||||
|
}
|
||||||
|
|
||||||
|
def analyze_metrics_with_ai(metrics):
|
||||||
|
"""Use Ollama to analyze system metrics"""
|
||||||
|
prompt = f"""
|
||||||
|
Analyze these system metrics and provide insights:
|
||||||
|
|
||||||
|
Timestamp: {metrics['timestamp']}
|
||||||
|
Uptime: {metrics['uptime']}
|
||||||
|
Disk: {metrics['disk']}
|
||||||
|
Memory: {metrics['memory']}
|
||||||
|
|
||||||
|
Provide a brief summary and any recommendations.
|
||||||
|
"""
|
||||||
|
|
||||||
|
response = requests.post(f"{OLLAMA_URL}/api/generate", json={
|
||||||
|
"model": "mistral:7b",
|
||||||
|
"prompt": prompt,
|
||||||
|

|
||||||
|
})
|
||||||
|
|
||||||
|
if response.status_code == 200:
|
||||||
|
return response.json().get('response', 'No analysis available')
|
||||||
|
else:
|
||||||
|
return "AI analysis unavailable"
|
||||||
|
|
||||||
|
def main():
|
||||||
|
print("System Health Dashboard")
|
||||||
|
print("=" * 50)
|
||||||
|
|
||||||
|
metrics = get_system_metrics()
|
||||||
|
analysis = analyze_metrics_with_ai(metrics)
|
||||||
|
|
||||||
|
print(f"Timestamp: {metrics['timestamp']}")
|
||||||
|
print(f"Uptime: {metrics['uptime']}")
|

||||||
|
if __name__ == "__main__":
|
||||||
|
main()
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Slack/Discord Bot Integration
|
||||||
|
|
||||||
|
Create a bot that provides AI assistance in your communication channels:
|
||||||
|
|
||||||
|
```python
|
||||||
|
#!/usr/bin/env python3
|
||||||
|
# scripts/ai-bot.py
|
||||||
|
|
||||||
|
import requests
|
||||||
|
import json
|
||||||
|
|
||||||
|
def ask_ollama(question, model="llama3.3:8b"):
|
||||||
|
"""Send question to Ollama and get response"""
|
||||||
|
response = requests.post("http://localhost:11434/api/generate", json={
|
||||||
|
"model": model,
|
||||||
|
"prompt": question,
|
||||||
|
"stream": False
|
||||||
|
})
|
||||||
|
|
||||||
|
if response.status_code == 200:
|
||||||
|
return response.json().get('response', 'No response available')
|
||||||
|
else:
|
||||||
|
return "AI service unavailable"
|
||||||
|
|
||||||
|
# Example usage in a Discord bot
|
||||||
|
# @bot.command()
|
||||||
|
# async def ask(ctx, *, question):
|
||||||
|
# response = ask_ollama(question)
|
||||||
|
# await ctx.send(f"🤖 AI Response: {response}")
|
||||||
|
|
||||||
|
# Example usage in a Slack bot
|
||||||
|
# @app.command("/ask")
|
||||||
|
# def handle_ask_command(ack, respond, command):
|
||||||
|
# ack()
|
||||||
|
# question = command['text']
|
||||||
|
# response = ask_ollama(question)
|
||||||
|
# respond(f"🤖 AI Response: {response}")
|
||||||
|
```
|
||||||
|
|
||||||
|
## Performance Tips
|
||||||
|
|
||||||
|
### 1. Model Selection Based on Task
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Use appropriate models for different tasks
|
||||||
|
alias code-review='ollama run codellama:7b'
|
||||||
|
alias quick-question='ollama run mistral:7b'
|
||||||
|
alias detailed-analysis='ollama run llama3.3:8b'
|
||||||
|
alias general-chat='ollama run llama3.3:8b'
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Batch Processing
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/usr/bin/env bash
|
||||||
|
# scripts/batch-analysis.sh
|
||||||
|
|
||||||
|
# Process multiple files efficiently
|
||||||
|
files=("$@")
|
||||||
|
|
||||||
|
for file in "${files[@]}"; do
|
||||||
|
if [[ -f "$file" ]]; then
|
||||||
|
echo "Processing: $file"
|
||||||
|
cat "$file" | ollama run codellama:7b "Briefly review this code:" > "${file}.review"
|
||||||
|
fi
|
||||||
|
done
|
||||||
|
|
||||||
|
echo "Batch processing complete. Check .review files for results."
|
||||||
|
```
|
||||||
|
|
||||||
|
These examples demonstrate practical ways to integrate Ollama into your daily development workflow, home lab management, and automation tasks. Start with simple integrations and gradually build more sophisticated automations based on your needs.

# RAG + MCP + Task Master AI: Implementation Roadmap
|
||||||
|
|
||||||
|
## Executive Summary
|
||||||
|
|
||||||
|
This roadmap outlines the complete integration of Retrieval Augmented Generation (RAG), Model Context Protocol (MCP), and Claude Task Master AI to create an intelligent development environment for your NixOS-based home lab. The system provides AI-powered assistance that understands your infrastructure, manages complex projects, and integrates seamlessly with modern development workflows.

||||||
|
- Resource sharing with Jellyfin and other services
|
||||||
|
- Potential memory pressure during concurrent usage
|
||||||
|
- Good for general-purpose AI tasks
|
||||||
|
|
||||||
|
### Alternative: Dedicated AI Server
|
||||||
|

|
||||||
|
|
||||||
|
**When to Consider:**
|
||||||
|
- Heavy model usage impacting other services
|
||||||
|
- Need for GPU acceleration
|
||||||
|
- Multiple users requiring concurrent access
|
||||||
|
- Development of AI-focused applications
|
||||||
|
|
||||||
|
## Monitoring and Observability

||||||
|
|
||||||
|
### Metrics to Track
|
||||||
|
- **Memory Usage**: Model loading and inference memory
|
||||||
|
- **Response Times**: Model inference latency
|
||||||
|
- **Request Volume**: API call frequency
|
||||||
|
- **Model Usage**: Which models are being used
|
||||||
|
- **Resource Utilization**: CPU/GPU usage during inference
|
||||||
|
|
||||||
|
### Integration with Existing Stack
|
||||||
|
- Prometheus metrics export (if available)
|
||||||
|
- Log aggregation with existing logging infrastructure
