Preface : Binary deployment of kubernetes clusters plays a very important role in enterprise applications. It is very convenient to upgrade the cluster or set the validity period of the certificate, and it is also a hurdle that has to be crossed from entry to mastery in cloud native related work. Through this series of articles, you will start from the preparation of the virtual machine to build a safe and stable high-availability kubernetes cluster from zero to one using the binary method, and have a clear understanding of the deployment process of each component. I will show the complete cluster building process, and the key parts will be explained. And provide a one-stop, complete resource file package. I hope that through this series of studies, you can really learn valuable knowledge and better deal with the problems encountered in your work.
