Prerequisites

Setup Control Plane

To set up the control node, run the command below. This process takes around 4 minutes to complete:

vagrant up c2d-cka-cp

Wait until the node status changes to “Ready”:

kubectl get nodes -w
Show me
98° [:ansible-dev]└2 master(+175/-122)* ± kubectl get nodes -w
NAME         STATUS     ROLES           AGE   VERSION
c2d-cka-cp   NotReady   control-plane   23s   v1.28.15
c2d-cka-cp   Ready      control-plane   24s   v1.28.15

Setup Worker Nodes

Next, set up the worker nodes. This process will take approximately 11 minutes:

vagrant up c2d-cka-worker{1..3} --no-provision

Then, observe their progress as they join the cluster:

kubectl get nodes -w
Show me
[ostraaten@io3 ckad-study-guide (⎈|kubernetes-admin@kubernetes:N/A)]$ kubectl get nodes
NAME              STATUS   ROLES           AGE     VERSION
c2d-cka-cp        Ready    control-plane   25m     v1.28.15
c2d-cka-worker1   Ready    worker          11m     v1.28.15
c2d-cka-worker2   Ready    worker          8m14s   v1.28.15
c2d-cka-worker3   Ready    worker          4m34s   v1.28.15
