Kubernetes is an open-source container orchestration system for automating software deployment, scaling and management. What is a Kubernetes Cluster? Kubernetes is an open-source container orchestration system
Kubernetes is a framework for integrating and coordinating all the elements for running dynamic microservices-based applications. Without orchestration, running these applications in production would be impossible.
A Kubernetes ReplicationController manages clusters of pods using a reconciliation loop to push for a desired cluster state. This ensures that the requested number of pods run to the user's specifications. It can be used to create new pods if a node fails or to manage, replicate and scale u...
To understand how Kubernetes is able to provide these capabilities, it is helpful to get a sense of how it is designed and organized at a high level. Kubernetes can be visualized as a system built in layers, with each higher layer abstracting the complexity found in the lower levels. At i...
The basic difference between the two is that Docker runs on a single node while Kubernetes runs across a cluster. However, the two are complementary and work together. Docker can be used to create and run containers, enabling the preservation and sharing of images; thus a Docker which is bui...
A node is a worker machine in Kubernetes, previously known as a minion. A node may be a VM or physical machine, depending on the cluster. A Pod always run on Node and Node can have multiple pods. Each Node is managed by the Master and the Kubernetes master automatically handles schedulin...
What is Docker What Are the Components of Kubernetes? The key components of Kubernetes are clusters, nodes, and the control plane. Clusters contain nodes. Each node comprises a set of at least one worker machine. The nodes host pods that contain elements of the deployed application. The cont...
The ‘cluster’ is at the center of Kubernetes. It is the group of nodes that schedule and run the container workloads, called Pods. In each cluster there are ‘master’ nodes and ‘worker’ nodes. The ‘master’ node or nodes are the brains of the cluster and they schedule all ...
Kubernetes is a platform for running applications and services. It manages the full lifecycle of container-based applications, by automating tasks, controlling resources, and abstracting infrastructure.
Note:In managed Kubernetes services like AWS EKS, GCP GKE, or Azure AKS, the control plane nodes are managed by the service provider, eliminating the need for users to manage them directly. Components of worker nodes Nodes house components that manage and run the containers: ...
