Does a pod in Kubernetes inherit every kernel settings from its pod?

  • 772

I'm trying to see if my pods are using tcp_keepalive_time.

When I ssh into my node and run sysctl -a I see that there is value for tcp_keepalive_time, but pods don't have them when run the same command in the pod.

In this case, do pods inherit their node's kernel values?

How do I confirm that a pod has its node's kernel value when a pod does not show with sysctl -a command?

kernel

  1. This official documentation will help you to understand how to set up properties using sysctl in pod: Setting Sysctls for a Pod.

    You need to use net.ipv4.tcp_keepalive_time

    Hope this will help you.
