feat(taskserv): implement real-time version checking with configurable HTTP client
- Add: GitHub API integration for live version checking in taskserv management - Add: HTTP client configuration option (http.use_curl) in config.defaults.toml - Add: Helper function fetch_latest_version with curl/http get support - Fix: Settings path structure for prov_data_dirpath access pattern - Remove: Legacy simulation code for version checking - Update: Core configuration name from "provisioning-system" to "provisioning" - Clean: Remove obsolete example configs and infrastructure files

# Nushell Infrastructure Runtime Task Service
|
||||
|
||||
> **Security-First Shell Runtime for Cloud Native Infrastructure**
|
||||
|
||||
A secure, auditable Nushell runtime designed specifically for infrastructure servers, providing powerful scripting capabilities while maintaining strict security controls and operational safety.
|
||||
|
||||
## 🎯 Purpose
|
||||
|
||||
The Nushell task service provides a modern, secure shell environment for:
|
||||
- **Remote Script Execution**: Safe execution of automation scripts on infrastructure servers
|
||||
- **Observability**: Structured data collection for metrics, logs, and telemetry
|
||||
- **Infrastructure Management**: Configuration-driven server management and orchestration
|
||||
- **Security Auditing**: Complete audit trail of all shell operations and command execution
|
||||
|
||||
## 🏗️ Architecture
|
||||
|
||||
### Core Components
|
||||
|
||||
```
|
||||

|
||||
├── default/
|
||||
│ ├── prepare # Environment preparation script
|
||||
│ ├── install-nushell.sh # Nushell binary installation
|
||||
│ ├── env-nushell.j2 # Environment configuration template
|
||||
│ ├── config.nu.j2 # Secure Nushell configuration
|
||||

└── telemetry.nu # Telemetry and monitoring
|
||||
```
|
||||
|
||||
### Security Model
|
||||
|
||||
- **Read-Only Mode**: Default execution prevents destructive operations
|
||||
- **Command Filtering**: Allowlist/blocklist for command execution
|
||||
- **Path Restrictions**: Limited file system access to safe directories
|
||||
- **Session Timeouts**: Automatic session termination for security
|
||||
- **Audit Logging**: Complete command and operation logging
|
||||
- **Resource Limits**: CPU, memory, and network usage controls
|
||||
|
||||
## 📋 Installation Options
|
||||
|
||||
### 1. Standalone Installation
|
||||
|
||||
Install Nushell as a dedicated task service:
|
||||
|
||||
```bash
|
||||
./core/nulib/provisioning taskserv create nushell --infra <infrastructure-name>
|
||||
```
|
||||
|
||||
### 2. Integrated with OS Base Layer
|
||||
|
||||
Enable during OS installation for automatic deployment:
|
||||
|
||||
```toml
|

[taskserv]
|
||||
install_nushell = true
|
||||
nushell_readonly = true
|
||||
nushell_plugins = false
|
||||
nushell_execution_mode = "restricted"
|
||||
```
|
||||
|
||||
### 3. Conditional Installation by Server Role
|
||||
|
||||
Configure role-based installation:
|
||||
|
||||
```toml
|
||||
# Control nodes: Always install
|
||||
# Worker nodes: Optional based on needs
|
||||
[server.control]

use /home/admin/nushell/observability/telemetry.nu *
|
||||
|
||||
# Configure telemetry endpoint
|
||||
init-telemetry --endpoint "https://monitoring.example.com/api/metrics" --enable-health
|
||||
|
||||
# Start health monitoring with alerts
|
||||
health-monitoring --check-interval 60 --alert-endpoint "https://alerts.example.com/webhook"
|
||||
|
||||
# Send custom metrics
|
||||
let custom_metrics = {app_name: "web-server", response_time: 250, status: "healthy"}
|
||||
send-telemetry $custom_metrics --format "prometheus"
|
||||
```
|
||||
|
||||
## 🔧 Integration Patterns
|
||||
|
||||
### SSH Remote Execution
|
||||
|
||||
Execute Nushell scripts remotely via SSH:
|
||||
|
||||
```bash
|
||||
# Execute health check on remote server
|
||||
ssh server-01 'nu /home/admin/nushell/observability/collect.nu -c "status-check | to json"'
|
||||
|
||||
# Stream metrics collection
|
||||
ssh server-01 'nu -c "use /home/admin/nushell/observability/collect.nu *; health-monitor --duration 60 --interval 10"'
|
||||
```
|
||||
|
||||
### Container Integration
|
||||
|
||||
Use in containerized environments:
|
||||
|
||||
```dockerfile
|
||||
# Add to your infrastructure containers
|
||||
RUN curl -L https://github.com/nushell/nushell/releases/download/0.107.1/nu-0.107.1-x86_64-unknown-linux-gnu.tar.gz | tar xz
|
||||
COPY nushell-config/ /home/app/.config/nushell/
|
||||
ENV NUSHELL_EXECUTION_MODE=restricted
|
||||
ENV NUSHELL_READONLY_MODE=true
|
||||
```
|
||||
|
||||
### Kubernetes Jobs
|
||||
|
||||
Deploy as Kubernetes jobs for infrastructure tasks:
|
||||
|
||||
```yaml
|
||||
apiVersion: batch/v1
|
||||
kind: Job
|
||||
metadata:
|
||||
name: nushell-health-check
|
||||
spec:
|
||||
template:
|
||||
spec:
|
||||
containers:
|
||||
- name: nushell
|
||||
image: infrastructure/nushell-runtime:latest
|
||||
command: ["nu"]
|
||||
args: ["/scripts/health-check.nu"]
|
||||
env:
|
||||
- name: NUSHELL_EXECUTION_MODE
|
||||
value: "restricted"
|
||||
- name: NUSHELL_AUDIT_ENABLED
|
||||
value: "true"
|
||||
```
|
||||
|
||||
## 🛡️ Security Features
|
||||
|
||||
### Command Validation
|
||||
|
||||
- **Pre-execution validation**: All commands validated before execution
|
||||
- **Pattern matching**: Blocked dangerous command patterns
|
||||
- **Path validation**: File access restricted to safe directories
|
||||
- **Resource monitoring**: CPU, memory, and network usage tracked
|
||||
|
||||
### Audit Trail
|
||||
|
||||
Complete audit logging includes:
|
||||
- Command execution timestamps
|
||||
- User context and session information
|
||||
- Input/output data (configurable)
|
||||
- Error conditions and failures
|
||||
- Resource usage metrics
|
||||
|
||||
### Session Management
|
||||
|
||||
- **Automatic timeouts**: Sessions expire after inactivity
|
||||
- **Resource limits**: Memory and CPU usage constraints
|
||||
- **Network isolation**: Optional network access controls
|
||||
- **Privilege separation**: Non-privileged execution by default
|
||||
|
||||
## 📊 Monitoring and Observability
|
||||
|
||||
### Health Checks
|
||||
|
||||
```nu
|
||||
# System health overview
|
||||
status-check
|
||||
|
||||
# Detailed health monitoring
|
||||
health-monitor --interval 30 --duration 600 --output "/tmp/health-data.json"
|
||||
|
||||
# Remote health validation
|
||||
nu-health-check
|
||||
```
|
||||
|
||||
### Metrics Collection
|
||||
|
||||
Automated collection of:
|
||||
- **System metrics**: CPU, memory, disk, network
|
||||
- **Process metrics**: Running processes, resource usage
|
||||
- **Container metrics**: Docker/Podman container status
|
||||
- **Kubernetes metrics**: Pod status, resource utilization
|
||||
|
||||
### Log Processing
|
||||
|
||||
Advanced log analysis capabilities:
|
||||
- **Multi-format parsing**: JSON, syslog, Apache, Nginx
|
||||
- **Pattern extraction**: Error patterns, IP addresses, URLs
|
||||
- **Anomaly detection**: Statistical analysis of log patterns
|
||||
- **Time-series aggregation**: Bucketed metrics over time
|
||||
|
||||

|
||||
```
|
||||
|
||||
## 🚨 Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
**1. Permission Denied Errors**
|
||||
```nu
|
||||
# Check file permissions
|
||||
ls -la /home/admin/nushell/
|
||||
# Verify ownership
|
||||
ls -la ~/.config/nushell/
|
||||
```
|
||||
|
||||
**2. Command Blocked in Read-Only Mode**
|
||||
```nu
|
||||
# Check execution mode
|
||||
echo $env.NUSHELL_EXECUTION_MODE
|
||||
# Review blocked commands
|
||||
echo $env.NUSHELL_BLOCKED_COMMANDS
|
||||
```
|
||||
|
||||
**3. Session Timeout Issues**
|
||||
```nu
|
||||
# Check session timeout setting
|
||||
echo $env.NUSHELL_SESSION_TIMEOUT
|
||||
# Review audit log for session activity
|
||||
cat ~/nushell/audit.log | tail -20
|
||||
```
|
||||
|
||||
**4. Plugin Loading Failures**
|
||||
```nu
|
||||
# Register plugins manually
|
||||
nu ~/nushell/scripts/register-plugins.nu
|
||||
# Check plugin availability
|
||||
plugin list
|
||||
```
|
||||
|
||||
### Debug Mode
|
||||
|
||||
Enable debug logging for troubleshooting:
|
||||
|
||||
```bash
|
||||
# Set debug environment
|
||||
export NUSHELL_LOG_LEVEL=debug
|
||||
export NU_LOG_LEVEL=debug
|
||||
|
||||
# Run with verbose output
|
||||
nu --log-level debug /path/to/script.nu
|
||||
```
|
||||
|
||||
### Performance Issues
|
||||
|
||||
Monitor resource usage:
|
||||
|
||||
```nu
|
||||
# Check memory usage
|
||||
free -h
|
||||
|
||||
# Monitor CPU usage
|
||||
top -p $(pgrep nu)
|
||||
|
||||
# Review resource limits
|
||||
echo $env.NUSHELL_MAX_MEMORY
|
||||
echo $env.NUSHELL_MAX_CPU_TIME
|
||||
```
|
||||
|
||||
## 📈 Performance Considerations
|
||||
|
||||
### Resource Usage
|
||||
|
||||
- **Memory footprint**: ~50-100MB base usage
|
||||
- **CPU overhead**: Minimal during idle, scales with workload
|
||||
- **Disk usage**: ~20MB for binary + configs
|
||||
- **Network impact**: Controlled by security settings
|
||||
|
||||
### Optimization Tips
|
||||
|
||||
1. **Use streaming operations** for large datasets
|
||||
2. **Enable read-only mode** for security and performance
|
||||
3. **Limit session timeouts** to prevent resource leaks
|
||||
4. **Use structured data formats** (JSON, YAML) for efficiency
|
||||
5. **Batch telemetry data** to reduce network overhead
|
||||
|
||||
## 🔗 Integration with Other Services
|
||||
|
||||
### KCL Configuration Language
|
||||
|
||||
Optional integration with KCL for configuration validation:
|
||||
|
||||
```nu
|
||||
# Install KCL plugin (if enabled)
|
||||
plugin add nu_plugin_kcl
|
||||
|
||||
# Validate KCL configurations
|
||||
kcl run infrastructure.k | to json | from json
|
||||
```
|
||||
|
||||
### Monitoring Systems
|
||||
|
||||
Compatible with popular monitoring solutions:
|
||||
- **Prometheus**: Native metrics export format
|
||||
- **InfluxDB**: Line protocol support
|
||||
- **Grafana**: JSON data source integration
|
||||
- **ELK Stack**: Structured log output
|
||||
|
||||
### CI/CD Pipelines
|
||||
|
||||
Use in automation workflows:
|
||||
|
||||
```yaml
|
||||
# GitHub Actions example
|
||||
- name: Infrastructure Health Check
|
||||
run: |
|
||||
ssh ${{ secrets.SERVER_HOST }} 'nu -c "
|
||||
use /home/admin/nushell/observability/collect.nu *;
|
||||
status-check | to json
|
||||
"'
|
||||
```
|
||||
|
||||
## 📚 Best Practices
|
||||
|
||||
### Security
|
||||
|
||||
1. **Always use read-only mode** in production
|
||||
2. **Implement session timeouts** appropriate for your environment
|
||||
3. **Enable audit logging** for compliance and debugging
|
||||
4. **Restrict network access** unless specifically required
|
||||
5. **Regularly review command allowlists** and access patterns
|
||||
|
||||
### Performance
|
||||
|
||||
1. **Use streaming operations** for processing large datasets
|
||||
2. **Implement data pagination** for long-running queries
|
||||
3. **Cache frequently accessed data** using structured formats
|
||||
4. **Monitor resource usage** and adjust limits as needed
|
||||
|
||||
### Operational
|
||||
|
||||
1. **Document custom scripts** and their intended usage
|
||||
2. **Test scripts in development** before production deployment
|
||||
3. **Implement proper error handling** in automation scripts
|
||||
4. **Use version control** for custom observability scripts
|
||||
5. **Regular security audits** of command patterns and access logs
|
||||
|
||||
