Kubernetes is a Container Orchestration Engine designed to host containerized applications on a set of nodes, commonly referred to as a cluster. Using a systems modeling approach, this series aims to advance the understanding of Kubernetes and its underlying concepts. The Kubernetes Scheduler is a core component of Kubernetes: After a user or a controller creates a Pod, the Kubernetes Scheduler, monitoring the Object Store for unassigned Pods, will assign the Pod to a Node.
Then, the Kubelet, monitoring the Object Store for assigned Pods, will execute the Pod.
