<p>I want to access my Kubernetes cluster API in Go to run <code>kubectl</code> command to get available namespaces in my k8s cluster which is running on google cloud.</p>

<p>My sole purpose is to get namespaces available in my cluster by running <code>kubectl</code> command: kindly let me know if there is any alternative.</p>

<p>You can start with <a href="https://github.com/kubernetes/client-go" rel="nofollow noreferrer"><code>kubernetes/client-go</code></a>, the Go client for Kubernetes, made for talking to a kubernetes cluster. (not through kubectl though: directly through the Kubernetes API)</p>

<p>It includes a <a href="https://github.com/kubernetes/client-go/blob/03bfb9bdcfe5482795b999f39ca3ed9ad42ce5bb/listers/core/v1/namespace.go#L28-L35" rel="nofollow noreferrer"><code>NamespaceLister</code>, which helps list Namespaces</a>.</p>
