Once again, the architecture is clear: three virtual machine CentOS 7.4 systems, Docker 17, IP 10.10.90.105 to 107, 105-bit master, and the next master-related components installed on this machine.The ETCD cluster is 3 units, which are reused for each of the 3 virtual machines.As the core of k8s, the master node consists of three components, namely:Three componen

Controller manager and scheduler. To achieve this reliably, we are want to having one actor modifying state at a time, but we want replicated instances of th ESE actors, in case a machine dies. To achieve this, we is going to use a lease-lock with the API to perform master election. We'll use --leader-elect the flags for each scheduler and Controller-manager, using a lease in the API would ensure that's only 1 ins Tance of the Scheduler and Controlle

The basic principle is to use zookeeper to elect a master, and other masters are in the STANDBY state. Connect the standalone cluster to the same zookeeper instance and start multiple masters. With the election and state saving functions provided by zookeeper, one master can be elected, while other masters

Label:I. Deployment notes1.1 Implementation EnvironmentThe experimental environment for this document is as follows:Pgsql Host: 192.168.1.45Pgsql Standby Machine: 192.168.1.50Software and system versionsPgsql version: Pgsql 9.2.4Linux version: Redhat 5.81.2 Document DescriptionThis document details the dual-machine extension of PG, so that the Pgsql database is equipped with dual-machine hot-standby-stream replication function. Note that there is a master
