Improvement for k8s.io/docs/setup/production-environment/container-runtimes/

[k-jenkins2025]

The documentation only has
cat <<EOF | sudo tee /etc/sysctl.d/k8s.conf
net.ipv4.ip_forward = 1
EOF

Apply sysctl params without reboot

sudo sysctl --system

Please update to include

cat <<EOF | sudo tee /etc/modules-load.d/k8s.conf
overlay
br_netfilter
EOF

sudo modprobe overlay
sudo modprobe br_netfilter

cat <<EOF | sudo tee /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
net.ipv4.ip_forward = 1
EOF
sudo sysctl --system

Hi, I’d like to work on this issue.
I will verify the required kernel modules and sysctl parameters against the current kubeadm and networking documentation and propose a documentation update accordingly.
