# Verification

Validate the Provisioning platform installation and infrastructure health.

## Installation Verification

### CLI and Core Tools

```bash
# Check CLI version
provisioning version

# Verify Nushell
nu --version  # 0.109.1+

# Verify Nickel
nickel --version  # 1.15.1+

# Check SOPS and Age
sops --version  # 3.10.2+
age --version   # 1.2.1+

# Verify K9s
k9s version  # 0.50.6+
```

### Configuration Validation

```bash
# Validate all configuration files
provisioning validate config

# Check environment
provisioning env

# Show all configuration
provisioning allenv
```

Expected output:

```text
Configuration validation: PASSED
  - User config: ~/.config/provisioning/user_config.yaml ✓
  - System defaults: provisioning/config/config.defaults.toml ✓
  - Provider credentials: configured ✓
```

### Provider Connectivity

```bash
# List available providers
provisioning providers

# Test provider connection (UpCloud example)
provisioning provider test upcloud

# Test provider connection (AWS example)
provisioning provider test aws
```

## Workspace Verification

### Workspace Structure

```bash
# List workspaces
provisioning workspace list

# Show current workspace
provisioning workspace current

# Verify workspace structure
ls -la <workspace-name>/
```

Expected structure:

```text
workspace-name/
├── infra/          # Infrastructure Nickel schemas
├── config/         # Workspace configuration
├── extensions/     # Custom extensions
└── runtime/        # State and logs
```

### Workspace Configuration

```bash
# Show workspace configuration
provisioning config show

# Validate workspace-specific config
provisioning validate config --workspace <name>
```

## Infrastructure Verification

### Server Health

```bash
# List all servers
provisioning server list

# Check server status
provisioning server status <hostname>

# Test SSH connectivity
provisioning server ssh <hostname> -- echo "Connection successful"
```

### Task Service Health

```bash
# List installed task services
provisioning taskserv list

# Check service status
provisioning taskserv status <service-name>

# Verify service health
provisioning taskserv health <service-name>
```

### Cluster Health

For Kubernetes clusters:

```bash
# SSH to control plane
provisioning server ssh <control-hostname>

# Check cluster nodes
kubectl get nodes

# Check system pods
kubectl get pods -n kube-system

# Check cluster info
kubectl cluster-info
```

## Platform Services Verification

### Orchestrator Service

```bash
# Check orchestrator status
curl  [http://localhost:5000/health](http://localhost:5000/health)

# View orchestrator version
curl  [http://localhost:5000/version](http://localhost:5000/version)

# List active workflows
provisioning workflow list
```

Expected response:

```json
{
  "status": "healthy",
  "version": "x.x.x",
  "uptime": "2h 15m"
}
```

### Control Center

```bash
# Check control center
curl  [http://localhost:8080/health](http://localhost:8080/health)

# Access web UI
open  [http://localhost:8080](http://localhost:8080)  # macOS
xdg-open  [http://localhost:8080](http://localhost:8080)  # Linux
```

### Native Plugins

```bash
# List registered plugins
nu -c "plugin list"

# Verify plugins loaded
nu -c "plugin use nu_plugin_auth; plugin use nu_plugin_kms; plugin use nu_plugin_orchestrator"
```

## Security Verification

### Secrets Management

```bash
# Verify SOPS configuration
cat ~/.config/provisioning/.sops.yaml

# Test encryption/decryption
echo "test secret" > /tmp/test-secret.txt
sops -e /tmp/test-secret.txt > /tmp/test-secret.enc
sops -d /tmp/test-secret.enc
rm /tmp/test-secret.*
```

### SSH Keys

```bash
# Verify SSH keys exist
ls -la ~/.ssh/provisioning_*

# Test SSH key permissions
ls -l ~/.ssh/provisioning_* | awk '{print $1}'
# Should show: -rw------- (600)
```

### Encrypted Configuration

```bash
# Verify user config encryption
file ~/.config/provisioning/user_config.yaml

# Should show: SOPS encrypted data or YAML
```

## Troubleshooting Common Issues

### CLI Not Found

```bash
# Check PATH
echo $PATH | tr ':' '
' | grep provisioning

# Verify symlink
ls -l /usr/local/bin/provisioning

# Try direct execution
/path/to/project-provisioning/provisioning/core/cli/provisioning version
```

### Provider Authentication Fails

```bash
# Verify credentials are set
provisioning config show | grep -A5 providers

# Test with debug mode
provisioning --debug provider test <provider-name>

# Check network connectivity
ping -c 3 api.upcloud.com  # UpCloud
ping -c 3 ec2.amazonaws.com  # AWS
```

### Nickel Schema Errors

```bash
# Type-check schema
nickel typecheck <schema-file>.ncl

# Validate with verbose output
provisioning validate config --verbose

# Format Nickel file
nickel fmt <schema-file>.ncl
```

### Server SSH Fails

```bash
# Verify SSH key
ssh-add -l | grep provisioning

# Test direct SSH
ssh -i ~/.ssh/provisioning_rsa root@<server-ip>

# Check server status
provisioning server status <hostname>
```

### Task Service Installation Fails

```bash
# Check dependencies
provisioning taskserv dependencies <service>

# Verify server has resources
provisioning server ssh <hostname> -- df -h
provisioning server ssh <hostname> -- free -h

# Enable debug mode
provisioning --debug taskserv create <service>
```
