On a self-hosted instance of Ephemeral, you can configure the nodes where Ephemeral can schedule pods.
If your Kubernetes nodes are configured with taints, then you can configure the tolerations that enable the pods to be scheduled on the nodes. Overview of taints and tolerations in Kubernetes documentation.
You can also configure node selectors. Overview of node selectors in the Kubernetes documentation.
In the Helm chart, you use the following settings to configure the tolerations and node selectors.
Here are the settings for node selectors:
