Glossary

This document describes some frequently used glossaries in KubeSphere as shown below:

Object	Concepts
Project	It can be regarded as Kubernetes Namespace which is intended for use in environments with many users spread across multiple teams, or projects, provides virtual isolation for the resources in KubeSphere, see Namespace.
Pods	Pods, are the smallest deployable units of computing that can be created and managed in KubeSphere, see Pods.
Deployments	Deployments, are used to describe a desired state in a Deployment object, and the Deployment controller changes the actual state to the desired state at a controlled rate, see Deployments.
StatefulSets	StatefulSets, StatefulSet is the workload object used to manage stateful applications, such as MySQL, see StatefulSets.
DaemonSet	DaemonSet, A DaemonSet ensures that all (or some) Nodes run a copy of a Pod，such as fluentd or logstash, see DaemonSet.
Jobs	Jobs, A job creates one or more pods and ensures that a specified number of them successfully terminate, see Jobs.
CronJob	CronJob, it creates Jobs on a time-based schedule, a CronJob object is like one line of a crontab (cron table) file. It runs a job periodically on a given schedule, see CronJob.
Services	Services, A Kubernetes Service is an abstraction which defines a logical set of Pods and a policy by which to access them - sometimes called a micro-service. See Services.
Routes	Ingress, An API object that manages external access to the services in a cluster, typically HTTP, Ingress can provide load balancing, SSL termination and name-based virtual hosting, see Ingress.
Image Registry	Image registry, is used to store and distribute Docker Images, it could be public or private, see Image.
Volume	Persistent Volume Claim (PVC), is a request for storage by a user, allow a user to consume abstract storage resources, see PVC.
Storage Classes	A Storage Class provides a way for administrators to describe the “classes” of storage they offer, see StorageClasses.
Pipeline	Jenkins Pipeline is a suite of plugins which supports implementing and integrating continuous delivery pipelines into Jenkins, see Pipeline.
WorkSpace	Multitenancy based, is the basic unit that is used to manage projects, DevOps and different level users.
Nodes	A node is a worker machine that may be a VM or physical machine, depending on the cluster. Each node contains the services necessary to run pods and is managed by the master components. see Nodes.
