The Helm chart used to install your JupyterHub deployment has a lot of options for you to tweak. For a semi-complete reference list of the options, see the Configuration Reference.

## Applying configuration changes¶

The general method to modify your Kubernetes deployment is to:

1. Make a change to your config.yaml.

2. Run a helm upgrade:

RELEASE=jhub


Note that helm list should display <YOUR_RELEASE_NAME> if you forgot it.
3. Verify that the hub and proxy pods entered the Running state after the upgrade completed.
kubectl get pod --namespace jhub

For information about the many things you can customize with changes to your Helm chart through values provided to its templates through config.yaml, see the Customization Guide.
