Create a Deployment with 6 replicas of Pods based on the nginx:1.20 image

k create deploy www --image=nginx:1.20 --replicas=4

Where are the pods scheduled ?

The pods are splitted between worker1 and worker2 (because master node has a NoScheduled taint that the pods do not tolerate)

k get po -o wide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
www-644dfdf68b-6mk2w 1/1 Running 0 33s 10.38.0.1 worker2 <none> <none>
www-644dfdf68b-crdjl 1/1 Running 0 33s 10.32.0.6 worker1 <none> <none>
www-644dfdf68b-nhm7b 1/1 Running 0 33s 10.32.0.2 worker1 <none> <none>
www-644dfdf68b-tsw84 1/1 Running 0 33s 10.38.0.5 worker2 <none> <none>

Drain the worker1 node. What happened ?

k drain worker1 --ignore-daemonsets

The application pods have been evicted from worker1 and are now all running on worker2
