1. Brief introduction

After the release of Kubernetes v1.13, kubeadm officially entered GA and can be used in production. It is also a future development trend to deploy kubernetes clusters with kubeadm. At present, the corresponding image warehouse of Kubernetes also has an image site in Aliyun, which makes it easy and much easier to deploy Kubernetes clusters using kubeadm. This article uses kubeadm to lead you to quickly deploy Kubernetes v1.13.2.

Note: please do not just focus on deployment, if you are a novice, it is recommended to be familiar with deployment with binaries before learning to deploy with kubeadm. For binary deployment, please see other articles on my blog.
