The production Kubernetes cluster on Jetstream2 is running a very old version of Kubernetes - v1.22. This needs to be upgraded ASAP.

rkalyanapurdue commented 2 months ago

This needs to happen soon since we are unable to add new nodes to the Kubernetes cluster as v1.22 cannot be installed from package repos any more.

Had a repeat of the NFS access issues (https://github.com/I-GUIDE/CI_Platform/issues/11) following Jetstream2 outage, requiring new Kubernetes worker nodes to be created with the old v1.22

Tentatively plan for week of Jul 7

Steps:

Setup a Kubernetes cluster using the TerraForm/Ansible recipe
Make sure to retain current floating IP for the public JupyterHub since it is tied to the DNS entry
Modify NFS server exports to add the right fixed IPs for the new cluster nodes
