In the kubernetes component, the master node component mainly includes: kube-apiserver,kube-controller-manager,kube-scheduler and other three components, each component has different functions and responsibilities. Here we deploy the three components on the same machine and deploy three machines respectively.

Log in to the devops machine and visit the official address of kubernetes github to download the stable realease package to this machine.
