README

The Engine API is an HTTP API served by Docker Engine. It is the API the Docker client uses to communicate with the Engine, so everything the Docker client can do can be done with the API.

Most of the client's commands map directly to API endpoints (e.g. docker ps is GET /containers/json). The notable exception is running containers, which consists of several API calls.

Errors

The API uses standard HTTP status codes to indicate the success or failure of the API call. The body of the response will be JSON in the following format:

{
  \"message\": \"page not found\"
}

Versioning

The API is usually changed in each release, so API calls are versioned to ensure that clients don't break. To lock to a specific version of the API, you prefix the URL with its version, for example, call /v1.30/info to use the v1.30 version of the /info endpoint. If the API version specified in the URL is not supported by the daemon, a HTTP 400 Bad Request error message is returned.

If you omit the version-prefix, the current version of the API (v1.44) is used. For example, calling /info is the same as calling /v1.44/info. Using the API without a version-prefix is deprecated and will be removed in a future release.

Engine releases in the near future should support this version of the API, so your client will continue to work even if it is talking to a newer Engine.

The API uses an open schema model, which means server may add extra properties to responses. Likewise, the server will ignore any extra query parameters and request body properties. When you write clients, you need to ignore additional properties in responses to ensure they do not break when talking to newer daemons.

Authentication

Authentication for registries is handled client side. The client has to send authentication details to various endpoints that need to communicate with registries, such as POST /images/(name)/push. These are sent as X-Registry-Auth header as a base64url encoded (JSON) string with the following structure:

{
  \"username\": \"string\",
  \"password\": \"string\",
  \"email\": \"string\",
  \"serveraddress\": \"string\"
}

The serveraddress is a domain/IP without a protocol. Throughout this structure, double quotes are required.

If you have already got an identity token from the /auth endpoint, you can just pass this instead of credentials:

{
  \"identitytoken\": \"9cbaf023786cd7...\"
}

Installation & Usage

Requirements

PHP 7.4 and later. Should also work with PHP 8.0.

Composer

To install the bindings via Composer, add the following to composer.json:

{
  "repositories": [
    {
      "type": "vcs",
      "url": "https://github.com/tslol/docker-api-php.git"
    }
  ],
  "require": {
    "GIT_USER_ID/GIT_REPO_ID": "*@dev"
  }
}

Then run composer install

Manual Installation

Download the files and include autoload.php:

<?php
require_once('/path/to/OpenAPIClient-php/vendor/autoload.php');

Getting Started

Please follow the installation procedure and then run the following:

<?php
require_once(__DIR__ . '/vendor/autoload.php');




$apiInstance = new OpenAPI\Client\Api\ConfigApi(
    // If you want use custom http client, pass your client which implements `GuzzleHttp\ClientInterface`.
    // This is optional, `GuzzleHttp\Client` will be used as default.
    new GuzzleHttp\Client()
);
$body = new \OpenAPI\Client\Model\ConfigCreateRequest(); // \OpenAPI\Client\Model\ConfigCreateRequest

try {
    $result = $apiInstance->configCreate($body);
    print_r($result);
} catch (Exception $e) {
    echo 'Exception when calling ConfigApi->configCreate: ', $e->getMessage(), PHP_EOL;
}

API Endpoints

All URIs are relative to http://localhost/v1.44

Models

Authorization

Endpoints do not require authorization.

Tests

To run the tests, use:

composer install
vendor/bin/phpunit

tslol / docker-api-php
