How do you document decisions and architecture for IPv6 in Kubernetes?

     [
            'description' => 'Enable IPv6 support in the Kubernetes cluster.',
            'date' => '2023-10-01',
            'rationale' => 'To ensure compatibility with modern networking standards and future-proof the infrastructure.'
        ],
        'Decision-2' => [
            'description' => 'Use dual-stack networking (IPv4/IPv6).',
            'date' => '2023-10-02',
            'rationale' => 'To accommodate existing applications while transitioning to an IPv6-first approach.'
        ],
    ];

    // Example output
    foreach ($architectureDecisions as $key => $decision) {
        echo "Key: $key\n";
        echo "Description: " . $decision['description'] . "\n";
        echo "Date: " . $decision['date'] . "\n";
        echo "Rationale: " . $decision['rationale'] . "\n\n";
    }
