Quick Start

<?php

use Snapflow\Docker\Docker;
use Snapflow\Docker\Adapter\DockerCLI;
use Snapflow\Docker\Adapter\RestartPolicy;
use Snapflow\Docker\Builder;

// Initialize
$docker = new Docker(new DockerCLI());

// Pull an image
$docker->pull('nginx:alpine');

// Create network and volume
$docker->createNetwork('frontend-network');
$docker->createVolume('static-assets', ['project' => 'blog']);

// Create and run a container using the builder
$containerId = Builder::create('nginx:alpine', 'blog-frontend')
    ->withPort(80, 8080)
    ->withEnv('NGINX_HOST', 'blog.local')
    ->withVolume('static-assets', '/usr/share/nginx/html')
    ->withNetwork('frontend-network')
    ->withRestart(RestartPolicy::UNLESS_STOPPED)
    ->withLabel('project', 'blog')
    ->build($docker);

// Container lifecycle operations
if ($docker->isRunning('blog-frontend')) {
    echo "Container is running!\n";

    // Pause and unpause
    $docker->pause('blog-frontend');
    $docker->unpause('blog-frontend');

    // View logs with timestamps
    $logs = $docker->logs('blog-frontend', tail: 20, timestamps: true);
    echo $logs;

    // Execute command in container
    $output = '';
    $docker->execute('blog-frontend', ['nginx', '-v'], $output);
    echo "Version: {$output}\n";

    // Get container stats
    $stats = $docker->getStats('blog-frontend');
    foreach ($stats as $stat) {
        echo "CPU: " . round($stat->getCpuUsage() * 100, 2) . "%\n";
        echo "Memory: " . round($stat->getMemoryUsage(), 2) . "%\n";
    }

    // Inspect container
    $info = $docker->inspect('blog-frontend');
    echo "Status: {$info['State']['Status']}\n";
}

// List containers with filters
$containers = $docker->list(['label' => 'project=blog']);

// Image management
$images = $docker->listImages();
if ($docker->imageExists('nginx:alpine')) {
    echo "Image exists\n";
}

// Cleanup
$docker->stop('blog-frontend');
$docker->remove('blog-frontend', force: true);
$docker->removeVolume('static-assets');
$docker->removeNetwork('frontend-network');
