<p>I just installed the controller via Helm, I can list the helm packages via <code>helm list</code>, but is it possible to list all the controllers running in the cluster via <code>kubectl</code> or <code>api-query</code>?</p>

<p>If you mean replication controller then you can list them by <code>kubectl</code>:</p>

<pre><code>kubectl get replicationcontroller -n my-namespace
</code></pre>

<p>Or list them all from all the namespaces:</p>

<pre><code>kubectl get rc --all-namespaces
</code></pre>

<p>And you can also use API:</p>

<pre><code>curl http://localhost:8080/api/v1/replicationcontrollers
</code></pre>

<p><strong>Update:</strong>
You can list other controller types like <code>replicaset</code> (<code>rs</code>), <code>deployment</code> (<code>deploy</code>), <code>statefulset</code>, <code>daemonset</code> (<code>ds</code>) and <code>job</code> in the same way.</p>
