[sudhakar042]

I feel these step or some link to do specific task are need to added in Linux Kernel Version Requirements

Load Required Kernel Modules

Create a configuration file for kernel modules:
cat <<EOF | sudo tee /etc/modules-load.d/k8s.conf
overlay
br_netfilter
EOF

Load the modules immediately:
sudo modprobe overlay
sudo modprobe br_netfilter

Configure Kernel Parameters for Networking

Create sysctl configuration for Kubernetes networking:
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

Apply the settings:
sudo sysctl --system
