Kubernetes Deployments, 2/2 PODs READY 5. But as we deleted one, we’ll need to reduce the replicas. There are several pods which should run three times across the cluster, one pod on each node.

You will see, that most deployments have 2 out of 3 pods running. Make sure you’re connected via vCenter to your Supervisor CLuster.

Deleting one SupervisorControlPlaneVM and make sure it’s not going to be re-deployedįirst, we change the wcpsvc.yaml configuration file to set minmasters and maxmasters from 3 to 2 nodes.Cleaning up failed pods due to node removal.Downscale the deployment replicas inside the Kubernetes cluster.Removing the Kubernetes node from the Kubernetes cluster.

Adjusting the wcpsvc.yaml configuration.When downscaling the SupervisorCluster we go through multiple steps: If proceeding, you should also be prepared to redeploy WCP at any point if something doesn’t work as expected. We’re going to interact with this one later on.ĭisclaimer: Before proceeding, please note that this is absolutely NOT supported and is not suitable for production environments. The kubernetes cluster orchestrates pods across all nodes, required to provide its functionality.Kubernetes within Supervisor Control Plane (One deployment is referred to as "agency") This service deploys the agent VMs and ensures the configured amount of VMs are present.Also, this service tells EAM how many SV VMs we want and orchestrates the update.This allows to see the namespaces in your vCenter UI. The WCP service on vCenter shares data between the Kubernetes cluster inside the Supervisor-VMs and the vCenter.ServicesĪs far as I understand, three components are majorily involved when deploying those Supervisor VMs:

If already running workload, this can result in quite some work. To reduce the nodes to two, you had to re-do the configuration change and re-deploy WCP. However one caveat is that once vCenter will be updated, the change is reverted and the third Supervisor VM will be deployed again. If you’re using this in your lab, you might already know that the control plane VMs can be reduced to 2 nodes by modifying the wcpsvc.yaml of the wcp service on the vCenter.Īs the smallest deployment size has 2 vCPUs, 8 GB RAM and 75 GB disk, you can safe same resources in a lab. to provision your TKC (Tanzu Kubernetes Cluster), also known as "Guest Cluster".provision your pods on your ESXi hosts,.Those VMs contain a Kubernetes cluster used to: 3 SV VMs in default deployment, used HOL for screenshot
