- `1` - General error
- `2` - Invalid command or arguments
- `3` - Configuration error
- `4` - Permission denied
- `5` - Resource not found

### Environment Variables

Control behavior through environment variables:

```
# Enable debug mode
export PROVISIONING_DEBUG=true

# Set environment
export PROVISIONING_ENV=production

# Set output format
export PROVISIONING_OUTPUT_FORMAT=json

# Disable interactive prompts
export PROVISIONING_NONINTERACTIVE=true
```

### Batch Operations

```
#!/bin/bash
# Example batch script

# Set environment
export PROVISIONING_ENV=production
export PROVISIONING_NONINTERACTIVE=true

# Validate first
if ! provisioning validate config --infra production; then
    echo "Configuration validation failed"
    exit 1
fi

# Create infrastructure
provisioning server create --infra production --yes --wait

# Install services
provisioning taskserv create kubernetes --infra production --yes
provisioning taskserv create postgresql --infra production --yes

# Deploy clusters
provisioning cluster create web-app --infra production --yes

echo "Deployment completed successfully"
```

### JSON Output Processing

```
# Get server list as JSON
servers=$(provisioning server list --infra my-infra --out json)

# Process with jq
echo "$servers" | jq '.[] | select(.status == "running") | .name'

# Use in scripts
for server in $(echo "$servers" | jq -r '.[] | select(.status == "running") | .name'); do
    echo "Processing server: $server"
    provisioning server ssh "$server" --command "uptime" --infra my-infra
done
```

## Command Chaining and Pipelines

### Sequential Operations

```
# Chain commands with && (stop on failure)
provisioning validate config --infra my-infra && \
provisioning server create --infra my-infra --check && \
provisioning server create --infra my-infra --yes

# Chain with || (continue on failure)
provisioning taskserv create kubernetes --infra my-infra || \
echo "Kubernetes installation failed, continuing with other services"
```

### Complex Workflows

```
# Full deployment workflow
deploy_infrastructure() {
    local infra_name=$1

    echo "Deploying infrastructure: $infra_name"

    # Validate
    provisioning validate config --infra "$infra_name" || return 1

    # Create servers
    provisioning server create --infra "$infra_name" --yes --wait || return 1

    # Install base services
    for service in containerd kubernetes; do
        provisioning taskserv create "$service" --infra "$infra_name" --yes || return 1
    done

    # Deploy applications
    provisioning cluster create web-app --infra "$infra_name" --yes || return 1

    echo "Deployment completed: $infra_name"
}

# Use the function
deploy_infrastructure "production"
```

## Integration with Other Tools

### CI/CD Integration

```
# GitLab CI example
deploy:
  script:
    - provisioning validate config --infra production
    - provisioning server create --infra production --check
    - provisioning server create --infra production --yes --wait
    - provisioning taskserv create kubernetes --infra production --yes
  only:
    - main
```

### Monitoring Integration

```
# Health check script
#!/bin/bash

# Check infrastructure health
if provisioning health check --infra production --out json | jq -e '.healthy'; then
    echo "Infrastructure healthy"
    exit 0
else
    echo "Infrastructure unhealthy"
    # Send alert
    curl -X POST https://alerts.company.com/webhook \
        -d '{"message": "Infrastructure health check failed"}'
    exit 1
fi
```

### Backup Automation

```
# Backup script
#!/bin/bash

DATE=$(date +%Y%m%d_%H%M%S)
BACKUP_DIR="/backups/provisioning/$DATE"

# Create backup directory
mkdir -p "$BACKUP_DIR"

# Export configurations
provisioning config export --format yaml > "$BACKUP_DIR/config.yaml"

# Backup infrastructure definitions
for infra in $(provisioning list infras --out json | jq -r '.[]'); do
    provisioning show settings --infra "$infra" --out yaml > "$BACKUP_DIR/$infra.yaml"
done

echo "Backup completed: $BACKUP_DIR"
```
