VMware Aria Operations (ex vROps Operations) is a powerful tool for monitoring infrastructure, virtual machines, predict resource demands or costs. Use cases is much more. One of them is ability to visualize, provide logs and information from the Tanzu Kuberentes Grid clusters. To obtain insightful data from the nodes you need to use dedicated addon – Management Pack for Kubernetes.
Troubleshooting of the cluster failure can be very demanding. After numerous unsuccessful attempts to fix the fault, we often report it to the support. VMware support, usually want from us to generate log bundle from that cluster.
TKG cluster can be deployed in a many ways. You can use simple YAML file and run it from the Supervisor. You can use some automation tool like Jenkins or create Kubernetes nodes from the TMC.
Apart from that, Terraform has a dedicated Tanzu Mission Control provider (plugin) to automate many processes.
Between Cluster v1beta1 API and earlier APIs are lot of configuration changes. One of them, is introduced in TKG 2.0 a new resource pool called ClusterClass.
The challenge is easy – vSAN datastore is running out of space and need to be expanded.
The whole process is a quite obvious. If there are free disk slots in a ESXi hosts, get a new drives, install in the servers and reconfigure vSAN capacity pool from the vCenter.
Last time, I deployed a new cluster. For this task, I used Tanzu Mission Control. Everything goes well, machines was created. Than, I connect to dedicated vSphere namespace and try to list tkc clusters. And a new cluster was not visible…Why?
If you’re using vSphere with Tanzu based on vSphere 7 and vSphere 8, you’ve probably noticed a lot of differences. From enabling Workload Management wizard to a separated section to editing the Supervisor cluster.
vSAN OSA (Original Storage Architecture) is one of two ways for implement a virtual storage solution. Another one is vSAN ESA (Express Storage Architecture). Today I want to focus on the first one. In short, vSAN enables to configure virtual storage across VMware ESXi hosts using local drives.
