RHEL8.7 compatibility issue vs RKE1

Rancher 1.x
1

Hi guys,
we have problem with RH8.7 and RKE1:

test #1

  1. reset VMs (rke remove)

  2. install latest iptables & kernel

  3. reboot

  4. deploy RKE

  5. latest 1.3.x RKE (1.3.19)

  6. latest 1.23.x K8S (1.23.16)

  7. deploy system components

  8. test - failed

  9. kubectl run -it --rm --restart=never --image=busybox:1.28 pbe-test – nslookup kubernetes.default.svc.cluster.local

  10. **no luck - timeout

test #2
we repeated the whole procedure, but in step “2” we installed the oldest version:
iptables-1.8.4-10.el8_2.1 kernel-4.18.0-193.6.3.el8_2

step 6: success

the problem looks similar as the topic:

thank you.
