arranging a host for it to write information to the ETCD. Of course, the things to deal with in this process is far from simple, need to consider a variety of decision factors, such as the same replication controller pod allocated to different hosts, to prevent the host node downtime on the business caused by a great impact, and how to consider resource balance, Thus, the resource utilization rate of the whole cluster is improved.

ClusterCluster is a collection of compute, storage, and network resources, and Kubernetes uses these resources to run various container-based applicationsMasterMaster is the brain of cluster, whose primary responsibility is scheduling, that is, deciding where the application will run. Master runs the Linux operating system, which can be either a physical machine or a virtual machine. To achieve high availability, you can run multiple master.NodeNode's
fault tolerance strategies The Kubernetes object is a "target record"--once the object is created, the Kubernetes system will continue to work to ensure that the object exists. By creating an object, you can effectively tell the Kubernetes system what the cluster workload looks like, which is the desired state of the Ku
