Investigating - Remove compute nodes

SRE is removing compute nodes from the cluster. Running applications may be impacted if they migrate for existing nodes to new nodes.

What should you do?
You can minimize the impact on your applications by scaling your services to more than one pod. In general, for applications to be able to continue to service clients, they should be scaled. Some pod workloads are not appropriate for scaling, such as a single-instance, non-replicated database using a persistent volume claim. In this situation, a deployment strategy of 'recreate' will ensure the pod is restarted after migration, although a brief outage will be experienced.
