<p>I have installed dask-gateway via the helm chart. I assume that I can provide an options handler in the <code>gateway.backend.extraConfig</code> section of the chart values. I would also assume I can then configure any option for <a href="https://gateway.dask.org/api-server.html#kube-cluster-config" rel="nofollow noreferrer">KubeClusterConfig</a>.</p>
<p>This will allow me to customize the image. How do I specify an image pull secret?</p>

<p>In fact, <code>KubeClusterConfig</code> contains the option <code>worker_extra_pod_config</code>, which is a dictionary merged into the pod spec, so <code>imagePullSecrets</code> can be specified here.</p>
