Hello, today I’ll be covering a quick workaround to resolve the situation you might face while deploying TCP RAN 1.5 setup in the lab.
Now we all are very much familiar about the deployment steps, and they are covered well in the VMware Telco Cloud Platform – RAN Platform Deployment Guide 1.5, so I’ll move to the topic of this write-up.
TCP RAN 1.5 supports TKG 1.4.2 and Kubernetes versions as 1.19.16, 1.20.4, 1.21.8.
However, while creating Kubernetes Cluster template from CaaS Infrastructure > Cluster Templates, as expected by default the latest version of Kubernetes version is not present. The version seen is ‘v1.20.5+vmware.2’ and not ‘v1.21.8+vmware.1’.
Even if you create cluster template with ‘v1.20.5+vmware.2’ and proceed with cluster creation, it will fail with error as “Unable to create k8s cluster with error only support to create the management cluster with kubernetes version [v1.21.8+vmware.1]”
Hence it is important that we should resolve the Kubernetes version displayed in the Template Detail, but how do we do it. Well answer is simple & below are the steps:
- Login to the TCP Control plane configuration.
- Go to ‘Appliance Summary’ tab
- Click RESTART in front of ‘Application Service’
- Wait for ~5 mins for service to restart properly.
Now create/edit the cluster template and the new version [v1.21.8+vmware.1] will be seen in the Kubernetes version field. 🙂
Hope this is helpful in your lab activities & exploring VMware Telco product portfolio.
