    --mode solo \
    --platform docker \
    --domain localhost \
    --services "orchestrator,mcp-server,control-center"

Features:

No UI required
Suitable for scripts
Progress logging to stdout
Exit codes for automation

3. Unattended Installation (Config File)

# Full automation from config file
provisioning-installer --unattended \
    --config provisioning/config/installer-examples/solo.toml

🔍 Troubleshooting

Issue: Config file not found

Error: Failed to load config from /path/to/config.toml

Solution:

# Check file exists
ls -l /path/to/config.toml

# Use absolute path
provisioning-installer --unattended --config $(pwd)/config.toml

# Or copy from examples
cp provisioning/config/installer-examples/solo.toml my-config.toml
provisioning-installer --unattended --config my-config.toml

Issue: Platform not detected

Error: No platforms detected

Solution:

# Check Docker is running
docker ps

# Check Podman is running
podman ps

# Check kubectl is configured
kubectl version --client

# Manual platform selection
provisioning-installer --headless --platform docker

Issue: Resource requirements not met

Error: Insufficient resources: need 4 cores, have 2

Solution:

Choose lower mode (e.g., solo instead of multi-user)

Override resource checks in config:

[resources]
min_cpu_cores = 2  # Lower requirement

Disable services to reduce load

Issue: MCP server not responding

Error: Failed to query MCP server

Solution:

# Check MCP server is running
curl http://localhost:3000/health

# Start MCP server
cd provisioning/platform/mcp-server
cargo run --release --bin provisioning-mcp-server

# Check logs
tail -f ~/.provisioning/logs/mcp-server.log

Issue: Webhook notifications failing

Error: Failed to send webhook notification

Solution:

Check webhook URL is correct

Verify network connectivity:

curl -X POST https://hooks.slack.com/... -d '{"text":"test"}'

Check webhook configuration in config.toml:

[unattended.notification]
webhook_url = "https://..."
retry_attempts = 3

🎯 Best Practices

1. Configuration Management

Use version control: Store config files in Git
Separate environments: dev.toml, test.toml, prod.toml
Template configs: Copy from examples, don't modify originals
Validate before deploy: Use --config-only to test configs

2. Security

Never commit secrets: Use KMS, SOPS, or environment variables
Enable auto-generate: Let installer generate secrets
Use TLS: Enable TLS for all services in production
Restrict access: Configure firewall rules and network policies

3. Deployment

Test in dev first: Always test configs in development
Use check mode: Run with --check before actual deployment
Enable rollback: Configure rollback_on_error = true
Monitor deployments: Use webhook notifications

4. Scaling

Start small: Begin with solo mode, scale to enterprise
Resource planning: Monitor usage, adjust resources accordingly
High availability: Use replicas for critical services
Load balancing: Enable for production deployments
