vanilla/garden-sites

Library for managing providing a list of sites and clusters from localhost or an orchestration server.

Installation

composer require vanilla/garden-sites

Usage

The entrypoint to usage of this library is through either the Garden\Sites\LocalSiteProvider, Garden\Sites\DashboardSiteProvider, Garden\Sites\OrchSiteProvider.

Configuring in Laravel

To configure this library in Laravel you need to setup the following 2 things.

conf/orch.php

use Garden\Sites\LaravelProviderFactory;

// This will inject your env variables into laravel config.
return LaravelProviderFactory::createLaravelConfigFromEnv("env");

Usage in the app

use Garden\Sites\LaravelProviderFactory;use Garden\Sites\SiteProvider;

/** @var SiteProvider $provider */
$provider = LaravelProviderFactory::providerFromLaravelConfig([\Config::class, 'get'])

/**
 * Site providers do various caching of results. By default an in-memory cache is used, but especially with an orch-client
 * it is recommended to configure a persistent cache like memcached or redis.
 * Caches must implement {@link CacheInterface}
 */

$cache = new RedisAdapter(/** Configuration here. */);
// or
$cache = new MemcachedAdapter(/** Configuration here. */);

$siteProvider->setCache($cache);

LocalSiteProvider

This provider reads site configurations from a local directory. The provider is configured with a path to the directory containing the site configurations.

.env

ORCH_TYPE="local"
ORCH_LOCAL_DIRECTORY_PATH="/path/to/site/configs"

Notably the path to the site configs must be a readable directory to the PHP process.

The local site provider works be reading php-based config files from a given directory. This reads all sites recognized by the vnla docker setup. For a site config to be recognized it must meet the following criteria

• The file has name matching one of the following patterns
  • /*.php - Becomes *.vanilla.localhost
  • /vanilla.localhost/*.php - Becomes vanilla.localhost/*
  • /e2e-tests.vanilla.localhost/*.php - Becomes e2e-tests.vanilla.localhost/*
• The file contains a valid PHP configuration files.
• The configuration contains the following values
  • Vanilla.SiteID
  • Vanilla.AccountID
  • Optional Vanilla.ClusterID. Defaults to cl00000

Clusters

By default all local sites are on the same cluster cl00000. You can bypass this by adding a Vanilla.ClusterID config to the site.

Cluster configurations may be added into the configs /clusters directory and are named /clusters/cl*.php. These should php config files just like sites. The configurations in these files will be merged with the site configs.

OrchSiteProvider

The orch site provider loads sites and clusters from a remote orchestration http server. Sites, clusters, and configs are cached for a 1 minute period.

.env

ORCH_TYPE="orchestration"
ORCH_BASE_URL="https://orchestration.vanilladev.com"
ORCH_TOKEN="SECRET_HERE"
# Optional hostname to force for orchestration (Force Proxy from localhost)
ORCH_HOSTNAME="ORCH_HOSTNAME";
# CSV of region IDs to accept sites from.
ORCH_REGION_IDS="yul1-prod1,sjc1-prod1";
ORCH_USER_AGENT="my-service";

DashboardSiteProvider

The orch site provider loads sites and clusters from a remote management-dashboard http server. Sites, clusters, and configs are cached for a 1 minute period.

.env

ORCH_TYPE="dashboard"
ORCH_BASE_URL="https://management-dashboard.vanilladev.com"
# JWT secret for management dashboard
ORCH_TOKEN="SECRET_HERE"
# Optional hostname to force for management dashboard (Force Proxy from localhost)
ORCH_HOSTNAME="ORCH_HOSTNAME";
# CSV of region IDs to accept sites from.
ORCH_REGION_IDS="yul1-prod1,sjc1-prod1";
ORCH_USER_AGENT="my-service";

Using site providers

Both OrchSiteProvider and LocalSiteProvider extend from SiteProvider and implement similar functionality.

use Garden\Sites\Exceptions\ClusterNotFoundException;
use Garden\Sites\Exceptions\SiteNotFoundException;
use Garden\Sites\SiteProvider;

function doSomethingWithProvider(SiteProvider $siteProvider)
{
    /**
     * Look up a site by ID.
     * Can throw an {@link SiteNotFoundException}
     */
    $site = $siteProvider->getSite(100);

    // List all sites
    $allSites = $siteProvider->getSites();

    /**
     * Look up a cluster by ID.
     * Can throw an {@link ClusterNotFoundException}
     */
    $cluster = $siteProvider->getCluster("cl10001");

    // List all clusters
    $allClusters = $siteProvider->getClusters();
}

Using Clusters and Sites

use Garden\Sites\Site;
use Garden\Sites\Cluster;

function doSomethingWithCluster(Cluster $cluster)
{
    // A few getters
    $clusterID = $cluster->getClusterID();
    $regionID = $cluster->getRegionID();
}

function doSomethingWithSite(Site $site)
{
    // A few getters
    $siteID = $site->getSiteID();
    $accountID = $site->getAccountID();
    $clusterID = $site->getClusterID();
    $baseUrl = $site->getBaseUrl();

    // HTTP Requests
    // This is a `garden-http` configured with the site's baseUrl
    // and set to throw on errors.
    $response = $site->httpClient()->get("/url", ["query" => "params"]);
    $response = $site->httpClient()->post("/url", ["body" => "here"]);
    $response = $site->httpClient()->patch("/url", ["body" => "here"]);
    $response = $site->httpClient()->put("/url", ["body" => "here"]);
    $response = $site->httpClient()->delete("/url");

    // System auth for an http request
    $site
        ->httpClient()
        ->withSystemAuth()
        ->get("/some-resource");

    // Ensure there is no auth on a request
    $site
        ->httpClient()
        ->withNoAuth()
        ->get("/some-resource");

    // Access the cluster
    $cluster = $site->getCluster();

    // Configs
    $configVal = $site->getConfigValueByKey("some.key.here", "fallback");

    // Configs are cached on the `Garden\Sites\Site` instance
    // You can clear them here.
    $site->clearConfigCache();

    // Check services hostnames the site should be using.
    $baseUrl = $site->getQueueServiceBaseUrl();
    $baseUrl = $site->getSearchServiceBaseUrl();
}
