Laravel Rancher

Rancher API wrapper for Laravel. This package provides a simple interface to Rancher's (awesome) API. Orchestrate your private container service with expressive, clean PHP.

Installation

Laravel Rancher uses compose to make installation a breeze.

Install via composer

composer require benmag/laravel-rancher

Register service provider Add the Laravel Rancher service provider to your config/app.php file in the providers key

'providers' => [
    // ... other providers
    Benmag\Rancher\RancherServiceProvider::class,
]

Rancher facade alias Then add the Rancher facade to your aliases key: 'Rancher' => Benmag\Rancher\Facades\Rancher::class.

Configuration

Configuration can be done via your .env file.

RANCHER_BASE_URL=http://localhost:8080/v1/
RANCHER_ACCESS_KEY=xxxxxxx
RANCHER_SECRET_KEY=xxxxxxx

You may also publish the config file to config/rancher.php for editing: php artisan vendor:publish --provider="Benmag\Rancher\RancherServiceProvider"

Notes

Make sure you have authentication enabled. Without this, you might experience some weird behaviour. I still need to look into changing Environments/Projects in a slightly more coordinated way but you should just be able to instantiate a new client instance.

Usage

Laravel Rancher is incredibly intuitive to use.

Introduction

Already configured everything and just want to see it in action? Take a look at the example code below.

<?php

namespace App\Http\Controllers;

use Rancher;
use App\Http\Controllers\Controller;

class HostController extends Controller
{
    public function index()
    {
        return response()->json(Rancher::host()->all());
    }
}

Host

Retrieving all Hosts

Rancher::host()->all();

Retrieve Host by ID

Rancher::host()->get("1h1");

Activate a Host by ID

Rancher::host()->activate("1h1");

Evacuate a Host by ID

Rancher::host()->evacuate("1h1");

Remove a Host by ID

Rancher::host()->remove("1h1");

Container

Retrieving all Containers

Rancher::container()->all();

Retrieve Container by ID

Rancher::container()->get("1i140");

Create a Container

use Rancher;
use Benmag\Rancher\Factories\Entity\Container;

$newContainer = new Container([
    'name' => 'HelloWorld',
    'description' => 'New container created via Laravel Rancher',
    'imageUuid' => "docker:ubuntu:14.04.3",
]);

Rancher::container()->create($newContainer);

Stack

Create a Stack

use Rancher;
use Benmag\Rancher\Factories\Entity\Stack;

$newStack = new Stack([
    'name' => "my-stack",
    'description' => 'An example stack',
    'dockerCompose' => "odoo:\n  image: odoo\n  ports:\n    - \"8069:8069\"\n  links:\n    - db\ndb:\n  image: postgres\n  environment:\n    - POSTGRES_USER=odoo\n    - POSTGRES_PASSWORD=odoo\n",
    'rancherCompose' => ".catalog:\n  name: \"Odoo\"\n  version: \"0.1-educaas\"\n  description: \"ERP management powered by Odoo\"\n  uuid: odoo-0\n  questions:\n\nodoo:\n",
    'externalId' => "catalog://community:odoo:0",
    'startOnCreate' => true
]);

Rancher::stack()->project('1a8')->create($newStack);

When creating a Stack, you will need to tell Rancher which Project you want to create it in.

Update an Stack

use Rancher;
use Benmag\Rancher\Factories\Entity\Stack;

$updatedStack = new Stack([
    'name' => "my-updated-stack",
    'description' => 'An updated stack',
]);

Rancher::stack()->update("1st312", $updatedStack);

Activate Services in an Stack

Rancher::stack()->activateServices("1st312");

Deactivate Services in an Stack

Rancher::stack()->deactivateServices("1st312");

Delete a Stack

Rancher::stack()->delete("1st312");

Project

Create a new Project

use Rancher;
use Benmag\Rancher\Factories\Entity\Project;

$project = new Project([
    'name' => 'Hello World',
]);

Rancher::project()->create($project);

Activate a Project

Rancher::project()->activate("1a8");

Deactivate a Project

Rancher::project()->deactivate("1a8");

Delete a Project

Rancher::project()->delete("1a8");

Service

Create a Service

use Rancher; 
use Benmag\Rancher\Factories\Entity\Service;

$newService = new Service([
    'name' => 'newService',
    'stackId' => '1st312',
    'launchConfig' => [
        'stdinOpen' => true,
        'imageUuid' => 'docker:ubuntu:14.04.3'
    ],
]);

Rancher::service()->project("1a8")->create($newService);

Update a Service

use Rancher;
use Benmag\Rancher\Factories\Entity\Service;

$updatedService = new Service([
    "description" => "I was updated",
    "name" => "db",
    "scale" => 1
]);

Rancher::service()->project("1a8")->update("1s23", $updatedService);

Add a Service Link

You may also add a single service link to the service. You can use the name value to specify a link alias.

use Rancher;

$serviceLink = ['name' => 'redis', 'serviceId' => '1s25'];

Rancher::service()->addServiceLink("1s24", $serviceLink);

Set Service Links

The setServiceLinks method will overwrite all of the links for that service.

use Rancher;

$serviceLinks = [
    ['name' => 'db', 'serviceId' => '1s23']
];

Rancher::service()->setServiceLinks("1s24", $serviceLinks);

Remove a Service Link

Individual service links can also be removed

use Rancher;

$remove = ['name' => 'db', 'serviceId' => '1s23'];

Rancher::service()->removeServiceLink("1s24", $remove);

Upgrade a Service

use Rancher;

$serviceUpgrade = [
    'inServiceStrategy' => [
        'batchSize' => 1,
        'intervalMillis' => 2000,
        'startFirst' => false,
        'launchConfig' => [
            'imageUuid' => 'docker:postgres',
            'startOnCreate' => true,
        ]
    ]
];

Rancher::service()->upgrade("1s23", $serviceUpgrade);

Finish a Service Upgrade

Rancher::service()->finishUpgrade("1s23");

Cancel a Service Upgrade

Rancher::service()->cancelUpgrade("1s23");

Rollback an Upgrade

Rancher::service()->rollback("1s23");

Cancel Rollback

Rancher::service()->cancelRollback("1s23");

Load Balancer Service

Create a Load Balancer

use Rancher; 
use Benmag\Rancher\Factories\Entity\LoadBalancerService;

$newLb = new LoadBalancerService([
    'name' => 'lb',
    'stackId' => '1st316',
    'launchConfig' => [
        'ports' => [
            "80",
            "8080"
        ],
        'imageUuid' => 'docker:rancher/lb-service-haproxy:v0.7.5'
    ],
    'lbConfig' => [
        'portRules' => [
            [
                'hostname' => '',
                'serviceId' => "1s583",
                'sourcePort' => 8080,
                'targetPort' => 80,
                'type' => 'portRule'
            ]
        ]
    ]
]);

Rancher::loadBalancerService()->project('1a8')->create($newLb);

Update a Load Balancer

use Rancher;
use Benmag\Rancher\Factories\Entity\LoadBalancerService;

$updatedLb = new LoadBalancerService([
    'name' => 'lb-updated',
    'stackId' => '1st316',
    'launchConfig' => [
        'ports' => [
            "80",
        ],
        'imageUuid' => 'docker:rancher/lb-service-haproxy:v0.7.5'
    ],
    'lbConfig' => [
        'portRules' => [
            [
                'hostname' => '',
                'protocol' => 'http',
                'serviceId' => "1s583",
                'sourcePort' => 80,
                'targetPort' => 80,
                'type' => 'portRule'
            ]
        ]
    ],
]);

Rancher::loadBalancerService()->project("1a8")->update("1s26", $updatedLb);

Add a Service Link to Load Balancer

You may also add a single service link to the service. You can use the name value to specify a link alias.

use Rancher;

$serviceLink = [
    'serviceId' => '1s10', 
    'ports' => [
        "hello.world.domain.com=80"
    ]
];

Rancher::loadBalancerService()->addServiceLink("1s27", $serviceLink);

Set Service Links for Load Balancer

The setServiceLinks method will overwrite all of the links for that load balancer.

use Rancher;

$serviceLinks = [
    [
        'serviceId' => '1s23',
        'ports' => [
            "hello.world.example.com=80",
        ]
    ]
];

Rancher::loadBalancerService()->setServiceLinks("1s24", $serviceLinks);

Remove a Service Link from Load Balancer

Individual service links can also be removed.

use Rancher;

$remove = ['serviceId' => '1s23'];

Rancher::loadBalancerService()->removeServiceLink("1s24", $remove);

    'certChain' => 'Your Chain Certs',
]);

Rancher::certificate()->create($cert);

Remove a certificate

use Rancher; 
Rancher::certificate()->delete($id);

Query Building

The wrapper also provides a convenient way for you to build fairly elaborate Rancher API requests. The following methods return the instance so you can chain more constraints onto the request as required.

Filters

Rancher lets you specify filters on API resources. The type of filter to apply is set via the key. Listed below is an example of all of the filter options.

$params = [
    'name' => 'Hello World', // name = "Hello World"
    'name_ne' => 'Hello World', // name != "Hello World"
    'name_notnull' => null, // name is not null
    'description_null' => null, // description is null
    'description_notlike' => 'Hello World', // description NOT LIKE '%Hello World%'
    'description_like' => 'Hello World', // description LIKE '%Hello World%'
    'name_prefix' => 'Hello', // name LIKE 'Hello%'
];

Rancher::stack()->filter($params)->get();

Remember: to change the field you filter on, change the key e.g. ['state' => 'active'] or ['description_notnull' => null]

Include

With Rancher, you can specify additional endpoints that should be eager loaded with the request through an include parameter. This functionality is exposed via the with method.

Rancher::service()->with(['instances'])->get("1s724");

Fields

Define additional fields from the API for the entity to dynamically expose. You can use this to enable access properties that are not explicitly defined by the entity class.

Rancher::service()->fields(['uuid'])->get("1s724");

Scope

By default, Rancher's scope is the default Project your credentials have access too. This chained method lets you easily change the scope to another project your credentials have access to on the fly.

Rancher::host()->scope('1a3302')->all();

Of course, you may utilize the setClient method to change the client to something completely new but if you want to change

All together now

Here is a simple example of how you can use method chaining to build elaborate Rancher API requests.

Rancher::services()
            ->scope('1a3302')
            ->with(['instances'])
            ->filter(['environmentId' => "1e512"])
            ->fields(['uuid'])
            ->get()

Handling Exceptions

The Rancher API will return errors as required. I am still looking for a nicer way to handle these exceptions... For the time being, simply wrap your call in a try/catch block.

try {
    
    Rancher::host()->deactivate("1h1");
    
} catch(ClientException $e) {
    $response = $e->getResponse();
    $responseBodyAsString = $response->getBody()->getContents();
    echo $responseBodyAsString;
}
