UI does not render CPI values in DS when selecting a newer kubernetes version to update #10930

Open gaktive opened 6 months ago

Internal reference: SURE-8310 Reported in 2.8.3

The downstream cluster was initially created using Terraform script, which clearly contained what we needed to make Vmware integration work. The TF includes the values for the CPI and CSI charts configuration.

The cluster is up and running and working as expected. The issue happens when selecting a newer kubernetes version to upgrade the cluster. In Rancher UI > Cluster Management > Select cluster > Edit Config > Cluster Configuration >Basics > Select a kubernetes version to upgrade cluster > Before saving to apply the upgrade, check the CSI and CPI in the Add-On Config tab.

The values will appear as empty for CPI when they should be accurately rendered.

Workaround: A) Adding/Typing manually the CPI values in the Rancher UI B) Modified the helm charts with additional manifests to indicated that some values are true

@rak-phillip was able to reproduce this in 2.9-head as of filing:

Reproduction Steps

  1. Provision a new vSphere RKE2 cluster via Rancher Dashboard
    • Make the following changes under Cluster Configuration => Basics
    • Change Kubernetes Version to the lowest available version in the list
    • Change Cloud Provider to vSphere
    • Under Cluster Configuration => Add-On Config, make the following adjustments
    • Enter values for vSphere CPI Configuration => vCenter Host, Data Centers, Username, & Password
    • Enter values for vSphere CSI Configuration => vCenter Host, Data Centers, Username, & Password
    • Ensure that all other required for provisioning a vSphere cluster are populated and correct; click Create
    • Wait for the vSphere cluster to enter a ready state
  2. Modify vSphere cluster created in step 1
    • Under Cluster Configuration => Basics, modify the Kubernetes version to the latest version in the list
    • Under Cluster Configuration => Add-On Config
    • All values for vSphere CPI Configuration are missing
    • All values for vSphere CSI Configuration are preserved

Optionally, if we change the selected Kubernetes version back to the value we selected in Step 1, we can observe that the vSphere CPI Configuration values are populated with their original values.

Possible candidate for 2.9.x backport
