Kubernetes Nodes And Pods

Objectives Learn about Kubernetes Pods. Learn about Kubernetes Nodes. Troubleshoot deployed applications. Kubernetes Pods A Pod is a group of one or more application containers such as Docker and includes shared storage volumes, IP address and information about how to run them. When you created a Deployment in Module 2, Kubernetes created a Pod to host your application instance. A Pod is a

A node is the smallest unit of computing hardware in Kubernetes. It is a representation of a single machine in your cluster. In most production systems, a node will likely be either a physical

What Is A Kubernetes Node? A Kubernetes node is either a virtual or physical machine that one or more Kubernetes pods run on. It is a worker machine that contains the necessary services to run pods, including the CPU and memory resources they need to run. Now, picture this Credit How Kubernetes Nodes work by Kubernetes.io

A cluster can contain many pods, related or unrelated and grouped under the tight logical borders called namespaces.quot There's another key concept, the node, which exists between the pod and cluster in this relationship. In Kubernetes, nodes are essentially the machines, whether physical or virtual, that host the pods.

By understanding nodes, pods and clusters, developers can make informed decisions when designing, deploying, and managing applications on Kubernetes.

The Process of Scheduling Pods on Nodes. The Kubernetes scheduler is responsible for assigning pods to nodes based on resource availability, affinity rules, and other constraints. Once a pod is scheduled, it is bound to the respective node and executed within its resources. This process ensures optimal resource utilization and load distribution

What is a Kubernetes Pod? A Kubernetes Pod is the smallest deployable unit within Kubernetes. It's essentially a group of one or more containers that share the same network namespace and storage. Pods ensure that containers that need to communicate closely are co-located on the same machine or Node, sharing resources like the IP address, storage, and even environment variables.

So this is Kubernetes Node and Pod and Cluster. Node is a worker computer in Kubernetes that can be either virtual or real, depending on the cluster. The control plane manages each node and the container operates logically in a pod, but it also requires a container runtime. A cluster is a collection of several nodes in a Kubernetes system.

If we want to filter pods by the node on which they are running, we can use the -field-selector spec.nodeNameltnode-namegt option. This command retrieves details about the pods running on a specific node in the Kubernetes cluster. For example, to list all pods running on node1, we can use the following command

Discover what Kubernetes, pods, and nodes are and how they work in this guide. Learn about its role in container orchestration, and how it helps manage, deploy, and scale applications. Expand your knowledge and explore the key concepts and benefits of Kubernetes for cloud-native applications.
