Upgrade failure due to uppercase hostname
Description
An issue may cause the upgrade to fail when the upgrade process attempts to create the upgrade-server deployment on nodes that use uppercase hostnames. Kubernetes automatically converts the kubernetes.io/hostname label to lowercase, which creates a mismatch because the upgrade process uses the original system hostname.
Solution
To address the issue, use one of the following options:
-
Manually edit the deployment and change the hostname label to lowercase.
-
Add a node label that preserves the uppercase hostname, as shown in the following example:
kubectl label node hostname-1 kubernetes.io/hostname-upper=HOSTNAME-1kubectl label node hostname-1 kubernetes.io/hostname-upper=HOSTNAME-1
