Installation

pip install k8s-helper-cli

Development Installation

git clone https://github.com/Harshit1o/k8s-helper.git
cd k8s-helper
pip install -e .

Prerequisites

• Python 3.8+
• kubectl configured with access to a Kubernetes cluster
• Kubernetes cluster (local or remote)

Important: k8s-helper requires an active Kubernetes cluster connection. Without a properly configured kubectl and accessible cluster, the commands will fail with configuration errors.

AWS EKS Features Prerequisites

For AWS EKS integration features:

• AWS CLI configured with appropriate credentials (aws configure)
• AWS IAM permissions for EKS, EC2, and IAM operations
• boto3 package (automatically installed with k8s-helper-cli)

Setting up Kubernetes (Choose one):

1. Local Development:

   • minikube
   • kind
   • Docker Desktop (Enable Kubernetes)

2. Cloud Providers:

   • Google Kubernetes Engine (GKE)
   • Amazon Elastic Kubernetes Service (EKS)
   • Azure Kubernetes Service (AKS)

3. Verify Setup:

   # Check if kubectl is configured
   kubectl cluster-info
   
   # List nodes to verify cluster access
   kubectl get nodes
   

Quick Start

from k8s_helper import K8sClient

# Initialize client with default namespace
client = K8sClient()

# Or specify a namespace
client = K8sClient(namespace="my-namespace")

# Create a deployment
client.create_deployment(
    name="my-app",
    image="nginx:latest",
    replicas=3,
    container_port=80
)

# Create a service
client.create_service(
    name="my-app-service",
    port=80,
    target_port=80,
    service_type="ClusterIP"
)

# Scale deployment
client.scale_deployment("my-app", replicas=5)

# Get logs
logs = client.get_logs("my-app-pod-12345")

# List resources
pods = client.list_pods()
deployments = client.list_deployments()
services = client.list_services()

Detailed Usage

Pod Management

# Create a pod
client.create_pod(
    name="my-pod",
    image="nginx:latest",
    container_port=80,
    env_vars={"ENV": "production", "DEBUG": "false"},
    labels={"app": "my-app", "version": "v1.0"}
)

# Delete a pod
client.delete_pod("my-pod")

# List all pods
pods = client.list_pods()
print(format_pod_list(pods))

# Describe a pod
pod_info = client.describe_pod("my-pod")

Deployment Management

# Create a deployment with environment variables
client.create_deployment(
    name="my-app",
    image="nginx:latest",
    replicas=3,
    container_port=80,
    env_vars={"ENV": "production"},
    labels={"app": "my-app", "tier": "frontend"}
)

# Scale deployment
client.scale_deployment("my-app", replicas=5)

# Delete deployment
client.delete_deployment("my-app")

# List deployments
deployments = client.list_deployments()
print(format_deployment_list(deployments))

# Wait for deployment to be ready
client.wait_for_deployment_ready("my-app", timeout=300)

Service Management

# Create a ClusterIP service
client.create_service(
    name="my-app-service",
    port=80,
    target_port=8080,
    service_type="ClusterIP"
)

# Create a LoadBalancer service
client.create_service(
    name="my-app-lb",
    port=80,
    target_port=80,
    service_type="LoadBalancer",
    selector={"app": "my-app"}
)

# Delete service
client.delete_service("my-app-service")

# List services
services = client.list_services()
print(format_service_list(services))

Monitoring Stack Setup

# Deploy complete monitoring stack
result = client.setup_monitoring(
    namespace="monitoring",
    grafana_service_type="NodePort",
    import_dashboard=True,
    wait_for_ready=True
)

if result['success']:
    print("✅ Monitoring stack deployed successfully!")
    print(f"🔑 Grafana credentials: {result['grafana']['admin_user']}/{result['grafana']['admin_password']}")
else:
    print(f"❌ Deployment failed: {result['error']}")

# Get monitoring stack information
info = client.get_monitoring_info("monitoring")
print(f"Prometheus running: {info['prometheus']['running']}")
print(f"Grafana running: {info['grafana']['running']}")
if info['grafana']['url']:
    print(f"Grafana URL: {info['grafana']['url']}")

Prometheus Target Management

# Add a new monitoring target
success = client.add_prometheus_target(
    job_name="my-app-metrics",
    targets=["my-app-service:8080", "10.0.1.100:9090"],
    namespace="monitoring",
    metrics_path="/metrics",
    scrape_interval="30s"
)

# List all monitoring targets
targets_info = client.list_prometheus_targets("monitoring")
for target in targets_info['targets']:
    print(f"Job: {target['job_name']}, Targets: {target['targets']}")

# Update existing target
client.update_prometheus_target(
    job_name="my-app-metrics",
    targets=["my-app-service:8080", "my-app-service:9090"],
    namespace="monitoring",
    scrape_interval="15s"
)

# Remove monitoring target
client.remove_prometheus_target("my-app-metrics", "monitoring")

Logs and Events

logs = client.get_logs("my-pod")

# Get logs with tail
logs = client.get_logs("my-pod", tail_lines=100)

# Get logs from specific container
logs = client.get_logs("my-pod", container_name="nginx")

# Get events
events = client.get_events()
print(format_events(events))

# Get events for specific resource
events = client.get_events("my-pod")

Resource Description

pod_info = client.describe_pod("my-pod")
print(format_yaml_output(pod_info))

# Describe deployment
deployment_info = client.describe_deployment("my-app")
print(format_json_output(deployment_info))

# Describe service
service_info = client.describe_service("my-service")

Quick Functions

For simple operations, use the convenience functions:

from k8s_helper import (
    quick_deployment,
    quick_service,
    quick_scale,
    quick_logs,
    quick_delete_deployment,
    quick_delete_service
)

# Quick deployment
quick_deployment("my-app", "nginx:latest", replicas=3)

# Quick service
quick_service("my-service", port=80)

# Quick scaling
quick_scale("my-app", replicas=5)

# Quick logs
logs = quick_logs("my-pod")

# Quick cleanup
quick_delete_deployment("my-app")
quick_delete_service("my-service")

Configuration

k8s-helper supports configuration through files and environment variables:

from k8s_helper import get_config

# Get configuration
config = get_config()

# Set default namespace
config.set_namespace("my-namespace")

# Set output format
config.set_output_format("yaml")  # table, yaml, json

# Set timeout
config.set_timeout(600)

# Save configuration
config.save_config()

Environment Variables

• K8S_HELPER_NAMESPACE: Default namespace
• K8S_HELPER_OUTPUT_FORMAT: Output format (table, yaml, json)
• K8S_HELPER_TIMEOUT: Default timeout in seconds
• K8S_HELPER_VERBOSE: Enable verbose output (true/false)
• KUBECONFIG: Path to kubectl config file

Output Formatting

The library provides several output formats:

from k8s_helper.utils import (
    format_pod_list,
    format_deployment_list,
    format_service_list,
    format_events,
    format_yaml_output,
    format_json_output
)

# Format as table
pods = client.list_pods()
print(format_pod_list(pods))

# Format as YAML
pod_info = client.describe_pod("my-pod")
print(format_yaml_output(pod_info))

# Format as JSON
deployment_info = client.describe_deployment("my-app")
print(format_json_output(deployment_info))

Error Handling

The library provides comprehensive error handling:

# All operations return None/False on failure
result = client.create_deployment("my-app", "nginx:latest")
if result is None:
    print("Failed to create deployment")

# Boolean operations return True/False
success = client.delete_deployment("my-app")
if not success:
    print("Failed to delete deployment")

# Use try-except for custom error handling
try:
    client.create_deployment("my-app", "nginx:latest")
except Exception as e:
    print(f"Error: {e}")

Advanced Usage

Using YAML Manifests

from k8s_helper.utils import create_deployment_manifest, create_service_manifest

# Create deployment manifest
deployment_manifest = create_deployment_manifest(
    name="my-app",
    image="nginx:latest",
    replicas=3,
    port=80,
    env_vars={"ENV": "production"},
    labels={"app": "my-app"}
)

# Create service manifest
service_manifest = create_service_manifest(
    name="my-app-service",
    port=80,
    target_port=80,
    service_type="ClusterIP",
    selector={"app": "my-app"}
)

print(format_yaml_output(deployment_manifest))

Working with Multiple Namespaces

# Create clients for different namespaces
prod_client = K8sClient(namespace="production")
dev_client = K8sClient(namespace="development")

# Deploy to production
prod_client.create_deployment("my-app", "nginx:1.20", replicas=5)

# Deploy to development
dev_client.create_deployment("my-app", "nginx:latest", replicas=1)

Monitoring and Health Checks

# Check namespace resources
resources = client.get_namespace_resources()
print(f"Pods: {resources['pods']}")
print(f"Deployments: {resources['deployments']}")
print(f"Services: {resources['services']}")

# Wait for deployment to be ready
if client.wait_for_deployment_ready("my-app", timeout=300):
    print("Deployment is ready!")
else:
    print("Deployment failed to become ready")

Examples

Complete Application Deployment

from k8s_helper import K8sClient

# Initialize client
client = K8sClient(namespace="my-app")

# Create deployment
client.create_deployment(
    name="web-app",
    image="nginx:latest",
    replicas=3,
    container_port=80,
    env_vars={"ENV": "production"},
    labels={"app": "web-app", "tier": "frontend"}
)

# Create service
client.create_service(
    name="web-app-service",
    port=80,
    target_port=80,
    service_type="LoadBalancer",
    selector={"app": "web-app"}
)

# Wait for deployment to be ready
if client.wait_for_deployment_ready("web-app"):
    print("✅ Application deployed successfully!")
    
    # Show status
    print("\nDeployments:")
    print(format_deployment_list(client.list_deployments()))
    
    print("\nServices:")
    print(format_service_list(client.list_services()))
    
    print("\nPods:")
    print(format_pod_list(client.list_pods()))
else:
    print("❌ Deployment failed!")

Cleanup Script

from k8s_helper import K8sClient

client = K8sClient(namespace="my-app")

# Clean up resources
resources_to_clean = [
    "web-app",
    "database",
    "cache"
]

for resource in resources_to_clean:
    print(f"Cleaning up {resource}...")
    client.delete_deployment(resource)
    client.delete_service(f"{resource}-service")

print("✅ Cleanup completed!")

Best Practices

1. Resource Management

# Use appropriate replica counts for high availability
k8s-helper apply my-app nginx:latest --replicas 3

# Monitor resource usage
k8s-helper status
k8s-helper list-deployments

2. Environment Management

# Use different namespaces for different environments
k8s-helper config --namespace production
k8s-helper config --namespace staging  
k8s-helper config --namespace development

3. Service Types

# Use ClusterIP for internal services
k8s-helper create-service internal-api --port 8080 --type ClusterIP

# Use LoadBalancer for external access
k8s-helper create-service public-web --port 80 --type LoadBalancer

4. Monitoring and Debugging

# Regular health checks
k8s-helper status
k8s-helper events

# Log monitoring
k8s-helper logs my-app

5. Configuration Management

# Set sensible defaults
k8s-helper config --namespace my-app
k8s-helper config --output-format yaml

Limitations

Important: k8s-helper requires an active Kubernetes cluster connection to function. The CLI and Python API will fail if:

• No kubectl configuration is found (~/.kube/config)
• No active Kubernetes cluster is available
• kubectl is not properly configured

Current CLI Limitations:

• Resource limits: --cpu-limit and --memory-limit options are not implemented
• Advanced logging: --tail, --follow, --container options are not available
• Advanced options: Some documented options like --env, --labels may not be available in all commands
• Batch operations: Multiple resource operations in single commands are not supported
• Advanced monitoring: --watch, --since, --all-namespaces options are not implemented

Error Handling:

If you see errors like:

ConfigException: Invalid kube-config file. No configuration found.
ConfigException: Service host/port is not set.

This means you need to:

1. Install and configure kubectl
2. Set up access to a Kubernetes cluster
3. Verify with kubectl cluster-info

The CLI provides core functionality for basic Kubernetes operations. For advanced features, use the Python API directly or kubectl.

Troubleshooting

Common Issues

1. Kubernetes Configuration Errors

Error: ConfigException: Invalid kube-config file. No configuration found.

Solution:

# Check if kubectl is installed
kubectl version --client

# Check if kubectl is configured
kubectl cluster-info

# If not configured, set up a cluster (example with minikube)
minikube start

2. Cluster Connection Issues

Error: ConfigException: Service host/port is not set.

Solution:

# Verify cluster is running
kubectl get nodes

# Check current context
kubectl config current-context

# Switch context if needed
kubectl config use-context <context-name>

3. Namespace Issues

Error: Namespace 'xyz' not found

Solution:

# List all namespaces
kubectl get namespaces

# Create namespace if needed
kubectl create namespace <namespace-name>

# Or use default namespace
k8s-helper config --namespace default

4. Permission Issues

Error: Forbidden: User cannot list pods

Solution:

# Check current user permissions
kubectl auth can-i list pods

# Check RBAC settings
kubectl get clusterrolebinding

Testing Without a Cluster

If you want to test the package without a real Kubernetes cluster, you can:

1. Use minikube (recommended for development):
