Docker Poller for Laravel
This package allows Laravel applications to interact with the Docker Engine API.
The Docker 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.
Installation
You can install the package via composer and then publish the assets:
composer require acamposm/docker-poller
php artisan vendor:publish --provider="Acamposm\DockerEngineApiPoller\DockerPollerServiceProvider"
Note: We try to follow SemVer v2.0.0.
Requirements
To use this packet, you must enable first the Docker Engine API, normally the Engine API listens on port 2375, but it is configurable.
Note: In production environments, you must always secure the API with SSL encryption and control who can perform request to this API.
Usage
Basic Initialization
First, create a DockerServer instance with the details of the docker server hosts.
Note: By default, the DockerServer class uses the default port (2375) and the protocol (http) of the Docker Engine API.
Docker Engine API over HTTP
use Acamposm\DockerEngineApiPoller\DockerServer;
$server = (new DockerServer())->server('localhost');or
use Acamposm\DockerEngineApiPoller\DockerServer;
$server = (new DockerServer())->insecure()->port(12375)->server('localhost');Docker Engine API over HTTPS
use Acamposm\DockerEngineApiPoller\DockerServer;
$server = (new DockerServer())->secure()->server('localhost');or
use Acamposm\DockerEngineApiPoller\DockerServer;
$server = (new DockerServer())->secure()->port(12375)->server('localhost');API Resources
Containers
Get Containers List
Get a list of the running containers in the docker host.
use Acamposm\DockerEngineApiPoller\DockerServer;
use Acamposm\DockerEngineApiPoller\DockerApiRequest;
use Acamposm\DockerEngineApiPoller\Enums\ResourceMethods;
$server = (new DockerServer())->server('192.168.10.101');
$containers_list = (new DockerApiRequest($server))
->containers(ResourceMethods::CONTAINERS_LIST)
->get();Get Container Details
To get the full details of a container...
use Acamposm\DockerEngineApiPoller\DockerServer;
use Acamposm\DockerEngineApiPoller\DockerApiRequest;
use Acamposm\DockerEngineApiPoller\Enums\ResourceMethods;
$server = (new DockerServer())->server('192.168.10.101');
$container_details = (new DockerApiRequest($server))
->containers(ResourceMethods::CONTAINERS_INSPECT, 'container_name')
->get();Get Container Stats
Get the resources used by a single container, then use the class ContainerMetrics to get the usage of a container.
use Acamposm\DockerEngineApiPoller\ContainerMetrics;
use Acamposm\DockerEngineApiPoller\DockerServer;
use Acamposm\DockerEngineApiPoller\DockerApiRequest;
use Acamposm\DockerEngineApiPoller\Enums\ResourceMethods;
$server = (new DockerServer())->server('192.168.10.101');
$container_stats = (new DockerApiRequest($server))
->containers(ResourceMethods::CONTAINERS_STATS, 'container_name')
->get();
$metrics = (new ContainerMetrics($container_stats))->metrics();
var_dump($metrics);The result will be a json object with the container statistics, ready to save to a database.
