Kubernetes Misconfiguration: Automated iptables Management Disabled
Abstract
이 Kubelet 구성은 Kubelet이 iptable을 구성하는 것을 방지합니다.
Explanation
기본적으로 Kubelets는 Pod 구성의 네트워킹 옵션을 기반으로
예제 1: 다음 Kubelet 구성은
iptables에 대해 필요한 변경을 수행합니다. Kubelet 구성에서 makeIPTablesUtilChains를 enabled:false로 설정하면 Kubelet이 컨테이너와 나머지 요소 간의 네트워크 트래픽을 관리하는 것을 방지할 수 있습니다. 그러면 Kubelet이 필요한 네트워크 보안 요구 사항을 적용하지 못하고 컨테이너에서 요청한 연결을 설정하지 못하게 됩니다.예제 1: 다음 Kubelet 구성은
makeIPTablesUtilChains: false.설정으로 인해 Kubelet이 iptables에 대해 필요한 변경을 수행하는 것을 방지합니다.
apiVersion: kubelet.config.k8s.io/v1beta1
kind: KubeletConfiguration
makeIPTablesUtilChains: false
