Created의 더 많은 메시지가와 Started eents for 설치-CNI and 옥양목-node`을.

kubectl logs calico-node-xzpp2 --namespace=kube-system -c install-cni OR calico-node은 빈 출력을 반환합니다.

어떻게이 문제를 자세히 조사합니까?

나는 패브릭 노드가 시작 실패 호스트에 journalctl -xe를 확인할 것입니다. kubectl logs calico-node...에서 아무것도 얻지 못하기 때문에 컨테이너가 시작하지 못하는 것처럼 들립니다.

ahah .. 재부팅 후/var/run/calico가 삭제되었습니다. 그것을 다시 만들었고 문제를 해결했습니다. 감사! – ufk
