Pod creation process in Kubernetes

Pod is the most basic deployment dispatch unit in Kubernetes, and it can contain container, which logically represents an instance of a certain application. For example, a Web site application is built from the front end, back end, and database, and these three components will run in their respective containers, so we can create a pod containing three container. This paper will do a simple analysis of the basic processing flow of

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 Controller-manager is running at once.That is, Control
