The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts about "how to install the cluster in Kubernetes". Next, please follow the editor to study!

Overview

Kubeadm is a cluster installation tool for kubernetes, which can quickly install a kubernetes cluster. The main purpose of installing kubernetes is to install its various images, and kubeadm has integrated the basic images we need to run kubernetes. However, due to domestic network reasons, these images cannot be pulled when building the environment. At this point, we only need to modify the image service provided for Aliyun to solve this problem.
