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. |
