Implementation Guide

Step 1: Initial Setup

First, configure your environment with the necessary tools and permissions:

# Install required CLI tools
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
chmod +x kubectl
sudo mv kubectl /usr/local/bin/

# Verify installation
kubectl version --client

Step 2: Configuration

Create a configuration file for your setup:

# config.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: app-config
  namespace: default
data:
  environment: "production"
  log_level: "info"
  max_connections: "100"
  timeout: "30s"

Code Examples

Example 1: Automation Script

#!/usr/bin/env python3
import boto3
import json
from datetime import datetime

def monitor_resources():
    """Monitor AWS resources and send alerts"""
    ec2 = boto3.client('ec2')
    cloudwatch = boto3.client('cloudwatch')

    # Get running instances
    response = ec2.describe_instances(
        Filters=[{'Name': 'instance-state-name', 'Values': ['running']}]
    )

    for reservation in response['Reservations']:
        for instance in reservation['Instances']:
            instance_id = instance['InstanceId']

            # Put custom metric
            cloudwatch.put_metric_data(
                Namespace='Custom/EC2',
                MetricData=[
                    {
                        'MetricName': 'InstanceCount',
                        'Value': 1,
                        'Unit': 'Count',
                        'Dimensions': [
                            {
                                'Name': 'InstanceId',
                                'Value': instance_id
                            }
                        ]
                    }
                ]
            )

    print(f"Monitoring completed at {datetime.now()}")

if __name__ == "__main__":
    monitor_resources()

Real-World Example
