kube-apiserver and etcd to essential concepts like Pods, Services, and advanced deployment strategies. Elevate your understanding of container orchestration with these high-yield flashcards.Preview terms and definitions before starting your study session.
kube-apiserver, etcd, kube-scheduler, kube-controller-manager, and cloud-controller-manager (optional).kube-apiserver.kube-apiserver is the front end of the Kubernetes control plane. It exposes the Kubernetes API, which is used by all other components and external users to communicate with the cluster. It validates and configures data for API objects like Pods, Services, etc.etcd in Kubernetes?etcd is a consistent and highly available key-value store used as Kubernetes' backing store for all cluster data. It stores the cluster's state, configuration data, and metadata, ensuring that all control plane components have a single source of truth.kube-scheduler.kube-scheduler watches for newly created Pods with no assigned node and selects a node for them to run on. It considers various factors like resource requirements, hardware/software/policy constraints, affinity/anti-affinity specifications, and data locality.kube-controller-manager?kube-controller-manager runs controller processes that regulate the state of the cluster. Each controller (e.g., Node Controller, Replication Controller, Endpoints Controller, Service Account Controller) is a separate process that watches for changes and moves the current state closer to the desired state.kubelet?kubelet is an agent that runs on each node in the cluster. It ensures that containers are running in a Pod. It takes a set of PodSpecs that are provided through various mechanisms and ensures that the containers described in those PodSpecs are healthy and running.kube-proxy?kube-proxy runs on each node and maintains network rules on the node. These rules allow network communication to your Pods from inside or outside the cluster. It handles network proxying for Kubernetes Services, enabling communication between Pods and external clients.Explore similar study materials created by the community
