This section contains frequently asked questions about the JupyterHub deployment.
For information on debugging Kubernetes, see Debugging.
You probably deleted the specific nodes, but not the Kubernetes cluster that
was controlling those nodes. Kubernetes is designed to make sure that a
specific set of resources is available at all times. This means that if you
only delete the nodes, but not the Kubernetes instance, then it will detect
the loss of computers and will create two new nodes to compensate.
JupyterHub isn’t handling any of the billing for your usage. That’s done
through whatever cloud service you’re using. For considerations about
managing cost with JupyterHub, see Appendix: Projecting deployment costs.
Each Helm Chart is packaged with a specific version of JupyterHub (and
other software as well). See see the Helm Chart repository
for information about the versions of relevant software packages.
