Solution Install a Kubernetes Cluster using kubeadm

Summary: Learn to install kubeadm and kubelet on control plane and worker node for setting up a Kubernetes cluster.

Key Notes

In this guide, you’ll learn how to install kubeadm along with the kubelet package on both the control plane and worker node (node1). To follow along, open two terminal sessions: one for the control plane and one via SSH connected to node1.
Step 1: Configure Container Runtime Forwarding Rules
Before installing the Kubernetes components, configure the necessary system forwarding rules on both nodes. Run the following command on both the control plane and node1:
=
net.ipv6.conf.default.use_tempaddr
kernel.kptr_restrict
fs.protected_symlinks
net.ipv4.conf.default.rp_filter
net.ipv4.conf.all.rp_filter
net.ipv4.conf.default.promote_secondaries
net.ipv4.ping_group_range
net.ipv4.conf.default.qdisc
net.bridge.bridge-nf-call-iptables
net.bridge.bridge-nf-call-ipv4
net.ipv4.ip_forward
sysctl:
“fs.protected_fifos”,
“fs.protected_regular”,
The output might also recommend installing a specific version of the Kubernetes packages. Keep this in mind as you progress through the installation.
Step 2: Install kubeadm, kubelet, and kubectl
Follow the steps below to install the Kubernetes components on both the control plane and node1. These instructions are based on Ubuntu; adjust as necessary for your distribution.
