k9s

pkg/k9s

This package provides a k9s client implementation for KSail.

Purpose

Provides a wrapper around the k9s terminal UI tool using its native Go packages, allowing KSail to launch k9s with appropriate configuration.

Features

• Native k9s Integration: Uses k9s's Go packages directly (no subprocess execution)
• Kubeconfig Support: Automatically configures k9s with the appropriate kubeconfig
• Argument Pass-through: All k9s arguments are passed through to the native k9s execution

Usage

import "github.com/devantler-tech/ksail-go/pkg/k9s"

// Create a k9s client
client := k9s.NewClient()

// Create a connect command that launches k9s
cmd := client.CreateConnectCommand("/path/to/kubeconfig")

// Execute the command (this will launch k9s)
err := cmd.Execute()
if err != nil {
    log.Fatal("Failed to launch k9s:", err)
}

Command Behavior

The CreateConnectCommand method creates a Cobra command that:

1. Launches k9s using its native Go packages
2. Automatically passes the kubeconfig path via --kubeconfig flag
3. Passes through all user-provided arguments to k9s
4. Connects k9s to the terminal for interactive use

Native Integration

This package integrates k9s using its exported cmd.Execute() function from github.com/derailed/k9s/cmd. This provides:

• Direct integration without subprocess overhead
• Full access to k9s's native flags and features
• Consistent behavior with standalone k9s

Testing

The package includes comprehensive tests that verify:

• Client creation
• Command structure and metadata
• Proper kubeconfig handling
