This a second part of the deployment vSphere IaaS Control Plane with Avi Load Balancer and VDS. In this post, we will enable Workload Management, create vSphere namespace and a cluster. Also, I’m going to deploy 3 tier app inside the Kubernetes workload cluster.
vSphere IaaS Control Plane with VMware Avi Load Balancer and vSphere Distributed Switch (VDS) provides a robust architecture for managing and delivering containerized applications in a virtualized environment. This setup, enables unified environment where Kubernetes applications can run alongside with traditional virtual machines. Administrators can deploy K8S workload clusters directly on vSphere environment. For some time, this product was know as vSphere with Tanzu or Tanzu Kubernetes Grid Service, aka TKGs.
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.
