I am copying this bug because: 



Description of problem:

Static container pod ( create pod yaml file in /etc/kubernetes/manifests/ on worker and let kubelet create the test pod)

met the following error: 

Warning  FailedCreatePodSandBox  <invalid>  kubelet  Failed to create pod sandbox: rpc error: code = Unknown desc = failed to create pod network sandbox k8s_static-web-ip-10-0-212-43.ap-southeast-1.compute.internal_zhouyt_937a3fb4b41f9b5b073f252037c0c642_0(ab9baefc8c6d7bf1664ec01cf81ea37bc76069556d7cedbfaca6150ac1e62541): error adding pod zhouyt_static-web-ip-10-0-212-43.ap-southeast-1.compute.internal to CNI network "multus-cni-network": plugin type="multus" name="multus-cni-network" failed (add): Multus: [zhouyt/static-web-ip-10-0-212-43.ap-southeast-1.compute.internal/937a3fb4b41f9b5b073f252037c0c642]: expected pod UID "937a3fb4b41f9b5b073f252037c0c642" but got "62ebfd59-5409-4c3e-8c10-069f5b1092e7" from Kube API


Version-Release number of selected component (if applicable):
4.10.0-0.nightly-2022-01-06-183041

How reproducible:
always

Steps to Reproduce:
1. Create pod yaml file in /etc/kubernetes/manifests/ of worker 

$oc debug node/worker1

sh-4.4# cd /etc/kubernetes/manifests/
sh-4.4# cat static-web.yaml 
apiVersion: v1
kind: Pod
metadata:
  name: static-web
  namespace: zhouyt
  labels:
    role: myrole
spec:
  containers:
    - name: web
      image: nginx
      ports:
        - name: web
          containerPort: 80
          protocol: TCP

2. Check the pod cannot be running
3. oc describe pod 

Actual results:

$ oc get pod -n zhouyt -o wide
static-web-ip-10-0-142-146.ap-southeast-1.compute.internal     0/1     ContainerCreating   0          75m   <none>   ip-10-0-142-146.ap-southeast-1.compute.internal   <none>           <none>


$ oc describe pod show the following error:
