Sysctl tuning

This example aims to demonstrate the use of an Init Container to adjust sysctl default values using kubectl patch.

kubectl patch deployment -n ingress-nginx ingress-nginx-controller \
    --patch="$(curl https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/docs/examples/customization/sysctl/patch.json)"

Changes:

Backlog Queue setting net.core.somaxconn from 128 to 32768
Ephemeral Ports setting net.ipv4.ip_local_port_range from 32768 60999 to 1024 65000

In a post from the NGINX blog, it is possible to see an explanation for the changes.
