[ERROR] The conditional check 'groups.get('kube_control_plane')' failed.

ubuntu22에서 ansible-core 이슈 발생! 

 

환경

• os : ubuntu22.04
• kubespray : v2.23.0
• ansible-core : v2.14

 

 

 

에러 내용

ansible-core 버전이 올라가면서 groups.get('kube_control_plane')가 None일 경우 false 처리가 아닌 "Conditional is marked as unsafe" 오류 발생하도록 변경되었다.

TASK [kubernetes/preinstall : Stop if either kube_control_plane or kube_node group is empty] ***
fatal: [baminet1]: FAILED! => {"msg": "The conditional check 'groups.get('kube_control_plane')' failed. The error was: Conditional is marked as unsafe, and cannot be evaluated."}

 

 

 

 

해결한 방법

groups.get(item) 자체가 None을 반환하더라도 오류가 발생하지 않도록 처리.

• roles/kubernetes/preinstall/tasks/0040-verify-settings.yml 수정

---
- name: Stop if either kube_control_plane or kube_node group is empty
  assert:
    that: "groups.get( item )"
