11.2.6. why I don't get all my ingress pod ? (3)

Hi everyone,
I need help. My worker node's role is none. I notice my worker role because y my lab 11.2. I suppose I expect to see the following:
student@cp:˜$ kubectl get pod --all-namespaces |grep nginx
default myingress-ingress-nginx-controller-mrqt5 1/1 Running 0 20s
default myingress-ingress-nginx-controller-pkdxm 1/1 Running 0 62s default nginx-b68dd9f75-h6ww7 1/1 Running 0 21h
three pos at namespace default

Instead of that, I got:
$ kubectl get pod --all-namespaces | grep nginx
default myingress-ingress-nginx-controller-858b9c449d-zb4lz 1/1 Running 1 (123m ago) 14h
default nginx-748c667d99-g5v66
I got two pods at namespaces default.

So I tried to understand myself, and I didn't. Therefore, I found the following:
student@cp:~$ kubectl get pod -o wide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
myingress-ingress-nginx-controller-858b9c449d-zb4lz 1/1 Running 1 (122m ago) 14h 192.168.242.69 cp
nginx-748c667d99-g5v66 1/1 Running 3 (122m ago) 7d17h 192.168.242.73 cp

As you can see, all pods are on my cp node.

kubectl get node -o wide
NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME
cp Ready control-plane 20d v1.26.1 10.2.0.4 Ubuntu 20.04.6 LTS 5.15.0-1031-gcp containerd://1.6.18
worker Ready 20d v1.25.1 10.2.0.5 Ubuntu 20.04.6 LTS 5.15.0-1031-gcp containerd://1.6.18
What am I doing wrong?
