Glossary

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

Object	Concepts
Project	It is Kubernetes Namespace which provides virtual isolation for the resources in KubeSphere, see Namespace.
Pod	A Pod is the smallest deployable computing unit that can be created and managed in KubeSphere, see Pods.
Deployment	Deployment is 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 Deployment.
StatefulSet	StatefulSet is the workload object used to manage stateful applications, such as MySQL, see StatefulSet.
DaemonSet	A DaemonSet ensures that all (or some) Nodes run a copy of a Pod，such as fluentd or logstash, see DaemonSet.
Job	A job creates one or more pods and ensures that a specified number of them successfully terminate, see Job.
CronJob	CronJob 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.
Service	A Kubernetes service is an abstraction object which defines a logical set of Pods and a policy by which to access them - sometimes called a micro-service. See Service.
Route	It is Kubernetes 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	It is Kubernetes Persistent Volume Claim (PVC). Volume is a request for storage by a user, allowing 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 StorageClass.
Pipeline	Jenkins Pipeline is a suite of plugins which supports implementing and integrating continuous delivery pipelines into Jenkins, see Pipeline.
WorkSpace	Workspace is a logical unit to organize your workload projects, DevOps projects, to manage resource access and share information within your team. It is an isolated working place for your team.
Node	A node is a worker machine that may be a virtual machine or physical machine, depending on the cluster setup. Each node contains the services necessary to run pods and is managed by the master components. see Node.
