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.
The control plane is the core of Kubernetes, orchestrating all cluster activities such as deploying applications, managing their states, scaling services, and handling failures. It is made up of the following elements: etcdsaves cluster information to a reliable distributed data store. kube-schedulera...
The main components in a Kubernetes cluster are the kube-apiserver, etcd, kube-scheduler, kube-controller-manager and cloud-controller-manager: API server:The application programming interface(API) server in Kubernetes exposes the KubernetesAPI(the interface used to manage, create and configure Kubernet...
API server The API server is the front end for the Kubernetes control plane, processing both internal and external requests to manage various aspects of the cluster. Replication sets These maintain a specified number of identical pods to ensure high availability and reliability. If a pod fails, ...
Kubernetes—also referred to as k8s or kube—was explicitly designed to automate the management ofcontainers—the standard unit of software that packages up code and all its dependencies. The orchestration tool is highly valued for running quickly and reliably in any infrastructure environment, whether...
Kubernetes, as a relatively new technology, has seen tremendous adoption in recent years, but security investment hasn’t always kept up.
A node, also known as aminion, is a worker machine in Kubernetes. It can be either a physical machine or a virtual machine (VM). Nodes have the necessary services to run pods and receive management instructions from master components. Services found on nodes includeDocker, kube-proxy and ku...
Kubernetes, specifically the Kubernetes Control Plane, is composed of a component services following the event-loop architecture: Image via https://medium.com/@tsuyoshiushio/kubernetes-in-three-diagrams-6aba8432541c kube-api-server kube-controller-manager kube-scheduler kubelet kube-proxy kube-dns etc...
Kubernetes is a container management system meant to be deployed on Docker-capable clustered environments. In this guide, we will discuss some of the basic …
While SSH is architecturally set in stone, higher-level software can learn a thing or two from Kubernetes about centralized configuration when managing a fleet of machines. See Teleport for an example of how this can be done. SSH could also borrow the credential management approach from kube...
