K8s Multi-Node On-prem Deployment on Hyper-V with Vagrant

Updated: Oct 2024

Always run the cert_verify.sh script at the places it suggests, and always ensure you are on the correct node when you do stuff. If cert_verify.sh shows anything in red, then you have made an error in a previous step. For the controlplane node checks, run the check on controlplane01 and on controlplane02

Cluster Details

Bootstrap a highly available Kubernetes cluster with end-to-end encryption between components and RBAC authentication.

• Kubernetes Latest version
• Container Runtime Latest version
• Weave Networking
• etcd v3.5.9
• CoreDNS v1.9.4

Node configuration

• Two control plane nodes (controlplane01 and controlplane02) running the control plane components as operating system services. This is not a kubeadm cluster as you are used to if you have been doing the CKA course. The control planes are not themselves nodes, therefore will not show with kubectl get nodes.
• Two worker nodes (node01 and node02)
• One loadbalancer VM running HAProxy to balance requests between the two API servers and provide the endpoint for your KUBECONFIG.
