Application
An application is an instance
installed by the Helm tool. It is a collection of resource objects such as
workloads, services and storage.
Glossary
Workload
A workload is an application running on Kubernetes. It
manages a group of pods that use the same image, and includes types such as
Deployment, StatefulSet and DaemonSet.
Job
A job processes short-lived workloads in batches and
ensures that one or more pods used for batch processing terminate successfully. Jobs
include one-time jobs and scheduled jobs.
Pod
A pod is the smallest unit of cluster scheduling and
management. Containers in the same pod share the same network and
storage.
Service
A service provides a unified access entry for pods, so
that applications can easily implement service discovery and load
balancing.
Ingress
An ingress is a collection of
HTTP or HTTPS routing rules used to access services inside a cluster from outside
the cluster. It provides externally accessible URLs, load balancing, SSL termination
and HTTP routing for cluster services.
Network Policy
A network policy controls communication between workloads,
and between workloads and the outside. By filtering inbound and outbound traffic, it
protects applications against network attacks.
PVC
A PVC (PersistentVolumeClaim) is used to persistently store
the data of a workload, so that the data is retained when a pod is restarted or
deleted.
ConfigMap
A configmap stores configuration data as key-value pairs
and can be mounted into a workload as a configuration file. A configmap decouples
environment configuration from the container image, which makes it easier to modify
application configuration.
Secret
A secret stores sensitive configuration in a Kubernetes
cluster, such as passwords and certificates, and can be used in a workload as a file
or an environment variable.
Microservices Application
A microservices application is a
collection of resource objects such as workloads, services and service mesh
resources. Microservices applications can be connected to the platform for visual
governance.
Service Topology
The service topology visually displays the invocation and
dependency relationships between microservices applications in the current
namespace, together with traffic monitoring data.
Repository
A repository stores Docker images and Helm charts uploaded by users. You can
upload your own modified images and charts to a repository, or download uploaded
Docker images and charts from a repository.
Artifact Sync
Artifact Sync connects to an external registry and
automatically synchronizes OCI artifacts such as container images and Helm charts to a
repository, achieving unified management of artifact assets.
YAML Template Repo
The YAML Template Repo stores YAML templates written by
users, and provides example templates for more than ten common Kubernetes resources
such as Deployment, Statefulset, Service, Configmap and PersistentVolumeClaim. You
can use the example templates in the YAML Template Repo to quickly write the YAML
text you need.
Application Market
The application market provides a rich set of official charts such as kafka,
zookeeper, mysql, redis and rabbitmq, which can be installed to a cluster with one
click and deployed as application instances.
One-Click Inspection
One-click inspection performs an all-round health check of key platform
resources and services with a single click, scores the health of the inspected
resources and services based on the results, and provides inspection suggestions and
an inspection report. It supports efficient O&M and helps keep platform resources
and services in optimal condition.
Alarm
An alarm monitors and responds to status changes in time series data, and
pushes alarm messages to specified endpoints through the notification service. You
can create alarms to monitor resources.
Endpoint
An endpoint is the way in which a user receives information about a subscribed
topic. Endpoint types include system, email, WeCom and DingTalk.
Message Template
The text template used when an alarm sends a message to an
endpoint.
Audit Log
Audit logs record platform resource operations, authentication activities, and Kubernetes resource operations to help you trace operations and troubleshoot issues.
Cluster
A cluster mainly refers to a Kubernetes cluster that runs
container applications. ZStack Zaku provides standardized,
highly available and stable Kubernetes clusters, and simplifies O&M operations
such as cluster deployment, scale-out, upgrade and high availability, so that you can
focus on your own upper-layer container applications.
Node Auto-Scaling Group
A node auto-scaling group is a node management unit that automatically adjusts
the number of nodes according to the business load of a cluster, achieving on-demand
resource allocation and cost optimization.
Node
A node is a basic component of a Kubernetes cluster. Nodes
are divided into control planes (Master) and compute nodes (Node).
GPU Pool
A GPU pool is a resource sharing unit formed by aggregating
multiple GPUs. It dynamically manages and allocates GPUs, improving resource
utilization and making resource allocation more flexible.
Storageclass
A storageclass (StorageClass) is a configuration template
used in Kubernetes to dynamically create PVCs. It defines the properties of a PVC,
the creation policy, and the required storage plug-in.
Local Storage
Local storage organizes local disks on cluster nodes into storage pools and provides persistent storage for workloads through storage classes.
External Network
An external network provides IP addresses for pods and LoadBalancer services in a cluster, allowing them to be accessed from outside the Kubernetes cluster.
Project
A project is a type of tenant used to implement resource
isolation and user permission management. After a user joins a project, the user can
have view or operation permissions on the resources of the project.
User
Users are created by an administrator or synchronized from
a 3rd-party authentication system, and are managed by administrators. A user must
join a project or be set as an administrator before having operation permissions on
the platform.
Namespace
A namespace provides virtual isolation for a Kubernetes
cluster. Resources in different namespaces are isolated from each
other.
AccessKey
An AccessKey is an identity credential for accessing
platform APIs. It has the same platform permissions as the current user, and consists
of an AccessKey ID and an AccessKey Secret.
