# SAL Kubernetes
Kubernetes cluster management and operations for the System Abstraction Layer (SAL).
## ⚠️ **IMPORTANT SECURITY NOTICE**
**This package includes destructive operations that can permanently delete Kubernetes resources!**
- The `delete(pattern)` function uses PCRE regex patterns to bulk delete resources
- **Always test patterns in a safe environment first**
- Use specific patterns to avoid accidental deletion of critical resources
- Consider the impact on dependent resources before deletion
- **No confirmation prompts** - deletions are immediate and irreversible
## Overview
This package provides a high-level interface for managing Kubernetes clusters using the `kube-rs` SDK. It focuses on namespace-scoped operations through the `KubernetesManager` factory pattern.
### Production Safety Features
- **Configurable Timeouts**: All operations have configurable timeouts to prevent hanging
- **Exponential Backoff Retry**: Automatic retry logic for transient failures
- **Rate Limiting**: Built-in rate limiting to prevent API overload
- **Comprehensive Error Handling**: Detailed error types and proper error propagation
- **Structured Logging**: Production-ready logging for monitoring and debugging
## Features
- **Namespace-scoped Management**: Each `KubernetesManager` instance operates on a single namespace
- **Pod Management**: List, create, and manage pods
- **Pattern-based Deletion**: Delete resources using PCRE pattern matching
- **Namespace Operations**: Create and manage namespaces (idempotent operations)
- **Resource Management**: Support for pods, services, deployments, configmaps, secrets, and more
- **Rhai Integration**: Full scripting support through Rhai wrappers
## Usage
### Basic Operations
```rust
use sal_kubernetes::KubernetesManager;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Create a manager for the "default" namespace
let km = KubernetesManager::new("default").await?;
// List all pods in the namespace
let pods = km.pods_list().await?;
println!("Found {} pods", pods.len());
// Create a namespace (no error if it already exists)
km.namespace_create("my-namespace").await?;
// Delete resources matching a pattern
km.delete("test-.*").await?;
Ok(())
}
```
### Rhai Scripting
```javascript
// Create Kubernetes manager for namespace
let km = kubernetes_manager_new("default");
// List pods
let pods = pods_list(km);
print("Found " + pods.len() + " pods");
// Create namespace
namespace_create(km, "my-app");
// Delete test resources
delete(km, "test-.*");
```
## Dependencies
- `kube`: Kubernetes client library
- `k8s-openapi`: Kubernetes API types
- `tokio`: Async runtime
- `regex`: Pattern matching for resource deletion
- `rhai`: Scripting integration (optional)
## Configuration
### Kubernetes Authentication
The package uses the standard Kubernetes configuration methods:
- In-cluster configuration (when running in a pod)
- Kubeconfig file (`~/.kube/config` or `KUBECONFIG` environment variable)
- Service account tokens
### Production Safety Configuration
```rust
use sal_kubernetes::{KubernetesManager, KubernetesConfig};
use std::time::Duration;
// Create with custom configuration
let config = KubernetesConfig::new()
.with_timeout(Duration::from_secs(60))
.with_retries(5, Duration::from_secs(1), Duration::from_secs(30))
.with_rate_limit(20, 50);
let km = KubernetesManager::with_config("my-namespace", config).await?;
```
### Pre-configured Profiles
```rust
// High-throughput environment
let config = KubernetesConfig::high_throughput();
// Low-latency environment
let config = KubernetesConfig::low_latency();
// Development/testing
let config = KubernetesConfig::development();
```
## Error Handling
All operations return `Result<T, KubernetesError>` with comprehensive error types for different failure scenarios including API errors, configuration issues, and permission problems.
## API Reference
### KubernetesManager
The main interface for Kubernetes operations. Each instance is scoped to a single namespace.
#### Constructor
- `KubernetesManager::new(namespace)` - Create a manager for the specified namespace
#### Resource Listing
- `pods_list()` - List all pods in the namespace
- `services_list()` - List all services in the namespace
- `deployments_list()` - List all deployments in the namespace
- `configmaps_list()` - List all configmaps in the namespace
- `secrets_list()` - List all secrets in the namespace
#### Resource Management
- `pod_get(name)` - Get a specific pod by name
- `service_get(name)` - Get a specific service by name
- `deployment_get(name)` - Get a specific deployment by name
- `pod_delete(name)` - Delete a specific pod by name
- `service_delete(name)` - Delete a specific service by name
- `deployment_delete(name)` - Delete a specific deployment by name
#### Pattern-based Operations
- `delete(pattern)` - Delete all resources matching a PCRE pattern
#### Namespace Operations
- `namespace_create(name)` - Create a namespace (idempotent)
- `namespace_exists(name)` - Check if a namespace exists
- `namespaces_list()` - List all namespaces (cluster-wide)
#### Utility Functions
- `resource_counts()` - Get counts of all resource types in the namespace
- `namespace()` - Get the namespace this manager operates on
### Rhai Functions
When using the Rhai integration, the following functions are available:
- `kubernetes_manager_new(namespace)` - Create a KubernetesManager
- `pods_list(km)` - List pods
- `services_list(km)` - List services
- `deployments_list(km)` - List deployments
- `namespaces_list(km)` - List all namespaces
- `delete(km, pattern)` - Delete resources matching pattern
- `namespace_create(km, name)` - Create namespace
- `namespace_exists(km, name)` - Check namespace existence
- `resource_counts(km)` - Get resource counts
- `pod_delete(km, name)` - Delete specific pod
- `service_delete(km, name)` - Delete specific service
- `deployment_delete(km, name)` - Delete specific deployment
- `namespace(km)` - Get manager's namespace
## Examples
The `examples/kubernetes/` directory contains comprehensive examples:
- `basic_operations.rhai` - Basic listing and counting operations
- `namespace_management.rhai` - Creating and managing namespaces
- `pattern_deletion.rhai` - Using PCRE patterns for bulk deletion
- `multi_namespace_operations.rhai` - Working across multiple namespaces
## Testing
Run tests with:
```bash
# Unit tests (no cluster required)
cargo test --package sal-kubernetes
# Integration tests (requires cluster)
KUBERNETES_TEST_ENABLED=1 cargo test --package sal-kubernetes
# Rhai integration tests
KUBERNETES_TEST_ENABLED=1 cargo test --package sal-kubernetes --features rhai
```
## Security Considerations
- Always use specific PCRE patterns to avoid accidental deletion of important resources
- Test deletion patterns in a safe environment first
- Ensure proper RBAC permissions are configured
- Be cautious with cluster-wide operations like namespace listing
- Consider using dry-run approaches when possible

//! SAL Kubernetes: Kubernetes cluster management and operations
//!
//! This package provides Kubernetes cluster management functionality including:
//! - Namespace-scoped resource management via KubernetesManager
//! - Pod listing and management
//! - Resource deletion with PCRE pattern matching
//! - Namespace creation and management
//! - Support for various Kubernetes resources (pods, services, deployments, etc.)
//!
//! # Example
//!
//! ```rust
//! use sal_kubernetes::KubernetesManager;
//!
//! #[tokio::main]
//! async fn main() -> Result<(), Box<dyn std::error::Error>> {
//! // Create a manager for the "default" namespace
//! let km = KubernetesManager::new("default").await?;
//!
//! // List all pods in the namespace
//! let pods = km.pods_list().await?;
//! println!("Found {} pods", pods.len());
//!
//! // Create a namespace (idempotent)
//! km.namespace_create("my-namespace").await?;
//!
//! // Delete resources matching a pattern
//! km.delete("test-.*").await?;
//!
//! Ok(())
//! }
//! ```
