The Kubernetes facade

Everything starts at the Kubernetes facade (RoundlyConsulting\KubernetesApi\Facades\Kubernetes). It hands out clusters — immutable clients — and, through them, resource objects (Pod, Deployment, …) that read and write the apiserver. Calls without a cluster name go to the default cluster from config/kubernetes.php:

use RoundlyConsulting\KubernetesApi\Facades\Kubernetes;

Kubernetes::pods()->get();                                   // default cluster, default namespace
Kubernetes::namespace('shop')->deployments()->get();         // default cluster, scoped to shop
Kubernetes::cluster('production')->services()->get();        // a named cluster

Kubernetes::ping();                                          // bool — does the apiserver answer?
Kubernetes::version()->gitVersion;                           // "v1.34.0" (a VersionInfo DTO)

Kubernetes::hasCluster('production');                        // bool
Kubernetes::clusters();                                      // ['default', 'production']

Kubernetes::url('https://127.0.0.1:6443')->withToken($token); // a new, blank ad-hoc cluster
Kubernetes::fromKubeConfig(context: 'staging');              // a new cluster from a kubeconfig context

Method reference

Method	Returns	What it does
`cluster(?string $name = null)`	`Cluster`	A configured or registered cluster — the default one when null. Resolved once and reused.
`hasCluster(string $name) · clusters()`	`bool · list<string>`	Whether a cluster exists; every configured and registered name.
`registerCluster(string $name, Closure $definition)`	`void`	Define a cluster in code; overrides a configured one of the same name.
`registerResource(string $name, string $class)`	`void`	Register a resource class under an accessor name for every cluster.
`namespace(string $namespace)`	`Cluster`	The default cluster, scoped to one namespace.
`ping() · version()`	`bool · VersionInfo`	Health and build information of the default cluster.
`url(string $url)`	`Cluster`	A new, blank ad-hoc cluster.
`connect(KubeConfig $config)`	`Cluster`	A new ad-hoc cluster from a resolved connection.
`fromKubeConfig(?string $path, ?string $context) · inCluster()`	`Cluster`	A new ad-hoc cluster from a kubeconfig context or the pod’s service account.
`resource(string $class)`	`Resource`	Any resource class, bound to the default cluster.
`pods(), deployments(), services(), … (33 accessors)`	the resource	Every packaged resource, bound to the default cluster.
`apps(), tenantNamespace(), …`	resource / macro result	A custom resource registered under that name, or a Cluster macro — on the default cluster.
`fake()`	`KubernetesFake`	Swap in the in-memory apiserver for tests — see Testing.

The Cluster handle

cluster(), namespace(), url(), connect(), fromKubeConfig() and inCluster() all return a RoundlyConsulting\KubernetesApi\Cluster. Every Cluster has the same 33 accessors as the facade, plus its own identity, health checks and a raw request() escape hatch that is authenticated, rate limited and faked like everything else:

$cluster = Kubernetes::cluster('production');

$cluster->name();                   // 'production' (null for ad-hoc clusters)
$cluster->defaultNamespace();       // from clusters.production.namespace
$cluster->hasResource('apps');      // is an accessor registered under that name?
$cluster->getUrl();                 // plus getToken(), getManagerName(), shouldVerify()…

// Raw escape hatch — authenticated, rate limited and faked like the typed resources
$response = $cluster->request('GET', '/apis/apps/v1/namespaces/shop/deployments', ['limit' => 10]);
$response->json('items');

Cluster method	Returns	Notes
`name()`	`?string`	The registration name; null for ad-hoc clusters (url(), connect(), fromKubeConfig(), inCluster()).
`url() · with…() · without…() · withManagerName() · withDefaultNamespace()`	a copy	Connection and credentials — see Connecting to a cluster.
`namespace(string) · namespaceScope()`	`Cluster · ?string`	A copy scoped to one namespace; the scope, if any.
`defaultNamespace()`	`string`	The soft default for namespaced resources.
`applyConfig(KubeConfig)`	a copy	Replaces URL, token, certificate, key, CA and verification.
`resource(class-string) · hasResource(string)`	`Resource · bool`	Any resource class bound to this cluster; whether an accessor name is registered.
`ping() · version()`	`bool · VersionInfo`	ping() is false on an apiserver error, a connection failure or a missing URL; a rate-limit exhaustion still throws.
`request($method, $path, $query = [], $body = '', $contentType = null, $stream = false)`	`Response`	Raw escape hatch through the cluster’s transport; a failed response throws KubernetesException.
`getUrl() · getToken() · getManagerName() · shouldVerify() · getPathTo…()`	readers	The credentials the cluster carries.

Clusters are immutable: every with…() / without…() call, url(), withManagerName(), withDefaultNamespace() and namespace() return a new cluster, so a client handed out by the facade can never be re-pointed or re-credentialed by another caller.
Named clusters are resolved once and reused; url(), connect(), fromKubeConfig() and inCluster() build a new ad-hoc cluster on every call.
Cluster::execute() is @internal — it opens the exec WebSocket for Pod::exec(); call exec() on a pod instead.
