Usage

The ApiClient connects to the Docker Remote API via HTTP. You can use the container "jarkt/docker-remote-api" to make the API available.

First create an instance of the ApiClient.

\jarkt\docker\ApiClient::construct ($host, $port [, $version ] )

Example:

$docker = new ApiClient(getenv('API_PORT_2375_TCP_ADDR'), getenv('API_PORT_2375_TCP_PORT'), 'v1.21');

(Haha, like 1.21 Gigawatt :-)

You can use various types of request methods to perform your API call. There are get, head, delete, post and put. The signatures are the same:

method ($path [, array $params [, requestHandlers\RequestHandler $requestHandler ]] )

For your call you have to serve the request path and optional an array of request parameters. Some requests require data in the request body - for these you can also give an instance of an implementation of a requestHandlers\RequestHandler. These implementation prepares a certain data type for the http api request.

Here are some examples:

$response = $docker->get('/containers/json');

$response = $docker->head('/containers/4fa6e0f0c678/archive', ['path' => '/path/on/container']);

$response = $docker->post('/containers/create', [], new requestHandlers\Json(['Image' => '4fa6e0f0c678']));

$response = $docker->put(
	'/containers/4fa6e0f0c678/archive',
	['path' => '/path/on/container'],
	new requestHandlers\Files('/path/on/local/machine')
);

From the response you can get the status code, to decide what type of ResponseHandler you need. Use a responseHandler\ResponseHandler to get informations from the response or to start actions on the local machine like unpacking a tar archive.

Here are some examples:

$response = $docker->get('/containers/json');
if($response->getStatus() === 200) {
	$responseHandler = new responseHandlers\Json($response);
	$containers = $responseHandler->getData();
	var_dump($containers);
}

$response = $docker->get('/containers/4fa6e0f0c678/archive', ['path' => '/path/on/container']);
if($response->getStatus() === 200) {
	$responseHandler = new responseHandlers\Files($response);
	$stat = json_decode(base64_decode($responseHandler->getHeader('x-docker-container-path-stat')), true);
	var_dump($stat);
	$responseHandler->extract('/path/on/local/machine');
}

Hint

Use the environment variable HOSTNAME as the container id of your own host.

Developers

Tests are running inside a docker container. Install all the test dependencies by going to the "containers" folder and type: docker-compose -f install.yml up

Update dependencies with: docker-compose -f update.yml up

Run the tests with: docker-compose up

This will make the API available through the container "jarkt/docker-remote-api" and run the tests against this endpoint.
