For this item, you will have to ssh and complete all tasks on these
nodes. Ensure that you return to the base node (hostname: ) when you have completed this item.
Context
As an administrator of a small development team, you have been asked to set up a Kubernetes cluster to test the viability of a new application.
Task
You must use kubeadm to perform this task. Any kubeadm invocations will require the use of the
--ignore-preflight-errors=all option.
Configure the node ik8s-master-O as a master node. .
Join the node ik8s-node-o to the cluster.
正解：
解説：
See the solution below.
Explanation
solution
You must use the kubeadm configuration file located at /etc/kubeadm.conf when initializingyour cluster.
You may use any CNI plugin to complete this task, but if you don't have your favourite CNI plugin's manifest URL at hand, Calico is one popular option:
https://docs.projectcalico.org/v3.14/manifests/calico.yaml
Docker is already installed on both nodes and apt has been configured so that you can install the required tools.
