How to change a Kubernetes pod tcp_keepalive

Question

I would like to change the default tcp keep alive value in a Kubernetes pod, what's the recommended approach?

Is the question about pure Docker, or Kubernetes? The answer will be very different. — David Maze, Sep 02 '21 at 21:37

You could do this via sysctls on the pod manifest in AKS/Kubernetes:

spec:
  securityContext:
    sysctls:
    - name: "net.ipv4.tcp_keepalive_time"
      value: "45"

Here is also further documentation:
