CSE3.0 - Worker Node Change Sizing class - Native Kubernetes

[lenzkercd]

We are currently having kubernetes [native] with the K8-Medium 4vCPU 4GB Memory up and running based on Cloud DIrector 10.2 & CSE 3.0.
We wanted to upgrade the worker nodes from the initial sizing class to a new one, but when we extract cluster.yaml via vcd cse cluster config CLUSTER_NAME , change the value of the sizing_class and apply it via vcd cse cluster apply CLUSTER_CONFIG.YAML we receive an error

Do you have any idea what is causing the problem? How can we change the config of the worker nodes from a virtual hardware perspective?

Thanks a lot and best regards,
Fabian

Hi Fabian,

CSE does not yet support changing the sizing class of the existing worker nodes. It also does not yet support the heterogenous clusters (worker nodes of different sizes). One workaround is to manually identify the worker VM on VCD and change the sizing policy on it. CSE should not complain, but we have not tested this out. Please try this on a sample cluster before changing it in the production environment.

Thanks
