243. Practice Test - Deploy a Kubernetes Cluster using Kubeadm
1. Install the kubeadm and kubelet packages on the controlplane and node01.
Use the exact version of 1.26.0-00 for both.

Container Runtimes
Note: Dockershim has been removed from the Kubernetes project as of release 1.24. Read the Dockershim Removal FAQ for further details. You need to install a container runtime into each node in the cluster so that Pods can run there. This page outlines what

Installing kubeadm
This page shows how to install the kubeadm toolbox. For information on how to create a cluster with kubeadm once you have performed this installation process, see the Creating a cluster with kubeadm page. Before you begin A compatible Linux host. The Kuber

2번째 단계에서 오류가 뜬다.
Note: In releases older than Debian 12 and Ubuntu 22.04, /etc/apt/keyrings does not exist by default. You can create this directory if you need to, making it world-readable but writeable only by admins.
/etc/apt/keyring 경로를 만들어야한다.
2. What is the version of kubelet installed?
3. How many nodes are part of kubernetes cluster currently? Are you able to run kubectl get nodes?
4. Lets now bootstrap a kubernetes cluster using kubeadm.
The latest version of Kubernetes will be installed.

5. Initialize Control Plane Node (Master Node). Use the following options:
- apiserver-advertise-address - Use the IP address allocated to eth0 on the controlplane node
- apiserver-cert-extra-sans - Set it to controlplane
- pod-network-cidr - Set to 10.244.0.0/16
Once done, set up the default kubeconfig file and wait for node to be part of the cluster.
eth0를 보면 192.12.244.12/24
cidr 는 10.244.0.1/24
이제 노드를 가져올 수 있다 .
6. Generate a kubeadm join token
Or copy the one that was generated by kubeadm init command
kubeadm join 192.12.244.12:6443 --token mqq4i8.usxdgtriyn085v78 \
--discovery-token-ca-cert-hash sha256:00bdc46e9d70d4ea1d900713b05c91bf95d99a48451b8de5faae3faa1c1667f4
7. Join node01 to the cluster using the join token
8. Install a Network Plugin. As a default, we will go with flannel
Refer to the official documentation for the procedure.
