README

PHP Docker Manager is a lightweight PHP library that provides an easy way to manage Docker containers (run/remove) from your PHP applications.

I developed this library for my personal needs. In consequence, it is not a complete Docker API client. It only provides the features I needed. See the API section for more details. Feel free to contribute to this project if you need more features.

Only the Docker Unix socket is supported. The TCP socket is not yet supported.

Requirements

• PHP extension sockets and curl must be enabled.
• Docker socket rights: the user running the PHP script must be in the docker group or have the rights to access the Docker socket.

Installation

Install the library using Composer:

composer require leoboiron/php-docker-manager

Quick start

use PhpDockerManager\Container\Config;
use PhpDockerManager\Manager;

// Create the manager with the Unix socket.
$manager = new Manager('unix:///var/run/docker.sock');

// Create a configuration for the container.
// Image name and tag are required.
$config = new Config('phpmyadmin/phpmyadmin', 'latest');

// Add some options.
$config
    ->setName('my-phpmyadmin')
    ->addLabel('traefik.enable', 'true')
    ->setNetwork('traefik')
    ->addEnvVar('PMA_ARBITRARY', '1')
;

// Run the container.
$instance = $manager->run($config);

// Get the status and id of the container.
echo 'Container status: ' . $manager->getStatus($instance)->name . PHP_EOL;
echo 'Container ID: ' . $instance->getId() . PHP_EOL;

// Remove the container.
$manager->remove($instance);
