I have installed dask-gateway via the helm chart. I assume that I can provide an options handler in the gateway.backend.extraConfig section of the chart values. I would also assume I can then configure any option for KubeClusterConfig.
This will allow me to customize the image. How do I specify an image pull secret?
In fact, KubeClusterConfig contains the option worker_extra_pod_config, which is a dictionary merged into the pod spec, so imagePullSecrets can be specified here.
