ktalk

ktalk is a kubectl plugin that converts natural language descriptions into kubectl commands using OpenAI's GPT-3.5-turbo. It makes interacting with your Kubernetes cluster more intuitive by allowing you to describe what you want to do in plain English.

Features

• Natural language to kubectl command conversion
• Interactive command execution with confirmation
• Powered by OpenAI's GPT-3.5-turbo model
• Safe command execution with user confirmation
• Support for complex kubectl queries
• Robust error handling and validation
• Command format validation
• HTTP status code checking
• Detailed error messages

Prerequisites

• Go 1.22.0 or later
• kubectl installed and configured
• OpenAI API key
• Access to a Kubernetes cluster

Installation

1. Clone the repository:

git clone https://github.com/yourusername/ktalk.git
cd ktalk

2. Build the plugin:

go build -o kubectl-ktalk

3. Install the plugin:

# For macOS/Linux
cp kubectl-ktalk /usr/local/bin/

4. Set up your OpenAI API key:

export OPENAI_API_KEY='your-api-key-here'

Usage

Basic syntax:

kubectl ktalk <your natural language query>

Examples

1. List containers in a namespace:

kubectl ktalk show me all containers in the kube-system namespace

2. Check pod status:

kubectl ktalk what's the status of pods in default namespace

3. Complex queries:

kubectl ktalk find all pods that are running as root user across all namespaces

How It Works

1. You provide a natural language description of what you want to do with your Kubernetes cluster
2. ktalk uses OpenAI's GPT-3.5-turbo to convert your description into the appropriate kubectl command
3. The generated command is validated to ensure it:
   • Starts with "kubectl"
   • Is properly formatted
   • Is safe to execute
4. The command is shown to you for confirmation
5. Upon confirmation (pressing Enter), the command is executed

Safety Features

• All generated commands are shown to you before execution
• You must explicitly confirm by pressing Enter to execute any command
• Commands are validated to ensure they start with "kubectl"
• The plugin uses GPT-3.5-turbo's understanding of Kubernetes to generate safe and appropriate commands
• HTTP status codes are checked for API responses
• Response format is thoroughly validated
• Empty or malformed responses are caught and reported

Error Handling

The plugin includes comprehensive error handling for:

• Missing or invalid OpenAI API key
• API request failures
• Invalid API responses
• Malformed commands
• Command execution errors
• User input errors

Technical Details

• Uses OpenAI's GPT-3.5-turbo model for optimal performance and cost
• Implements robust JSON response parsing
• Includes thorough type checking and validation
• Provides detailed error messages for debugging
• Uses Go's standard library for command execution
• Implements proper signal handling for command interruption
