Kubernetes-CentOS-Kernel

Kubernetes-CentOS-Kernel aims to build an enhanced CentOS kernel to run Kubernetes safely. If you are running Kubernetes on CentOS, you may encounter some critical issues that would crash your guest operating system. Kubernetes-CentOS-Kernel fixes those critical issues for you.

    Fixed according to net: tcp: close sock if net namespace is exiting
