Overview

coredns (System Resource Add-on, Mandatory)

CoreDNS is a DNS server that provides domain name resolution for Kubernetes clusters through chain plug-ins.

everest (System Resource Add-on, Mandatory)

everest is a cloud native container storage system, which enables clusters of Kubernetes v1.15.6 or later to use cloud storage through the Container Storage Interface (CSI).

npd

node-problem-detector (npd for short) is an add-on that monitors abnormal events of cluster nodes and connects to a third-party monitoring platform. It is a daemon running on each node. It collects node issues from different daemons and reports them to the API server. The npd add-on can run as a DaemonSet or a daemon.

dashboard

Kubernetes Dashboard is a general-purpose, web-based UI for Kubernetes clusters and integrates all commands that can be used in the CLI. It allows users to manage applications running in a cluster and troubleshoot faults, as well as manage the cluster itself.

autoscaler

The autoscaler add-on resizes a cluster based on pod scheduling status and resource usage.

metrics-server

metrics-server is an aggregator for monitoring data of core cluster resources.

cce-hpa-controller

cce-hpa-controller is a CCE-developed add-on, which can be used to flexibly scale in or out Deployments based on metrics such as CPU usage and memory usage.

prometheus

Prometheus is an open-source system monitoring and alerting framework. CCE allows you to quickly install Prometheus as an add-on.

web-terminal

web-terminal is an add-on that allows you to use kubectl on a web UI. It can connect to Linux by using WebSocket through a browser and provides APIs for integration into independent systems. It can be directly used as a service to obtain information through the configuration management database (CMDB) and log in to the server.

gpu-beta

gpu-device-plugin is a device management add-on that supports GPUs in containers. It supports only NVIDIA drivers.

huawei-npu

huawei-npu is a management add-on for Huawei NPU devices in containers.

volcano

Volcano provides general-purpose, high-performance computing capabilities, such as job scheduling, heterogeneous chip management, and job running management, serving end users through computing frameworks for different industries, such as AI, big data, gene sequencing, and rendering.

nginx-ingress

nginx-ingress provide application-layer forwarding functions, such as virtual hosts, load balancing, SSL proxy, and HTTP routing, for Services that can be directly accessed outside a cluster.

dew-provider

The dew-provider add-on is used to interconnect with , which allows you to mount secrets stored outside a cluster (that is, DEW for storing sensitive information) to pods. In this way, sensitive information can be decoupled from the cluster environment, preventing information leakage caused by program hardcoding or plaintext configuration.

dolphin

dolphin is a pod network monitoring add-on, which, in the current version, can be used to collect statistics about public network traffic of Kata containers in CCE Turbo clusters and common containers that use containerd as the runtime.

This add-on collects how many IPv4 packets and bytes are received and sent (including those sent to the public network). PodSelectors can be used to select monitoring backends to support multiple monitoring tasks and optional monitoring metrics. You can also obtain label information of pods. The monitoring information has been adapted to the Prometheus format. You can call the Prometheus API to view monitoring data.

node-local-dns

NodeLocal DNSCache improves cluster DNS performance by running DNS cache proxies as DaemonSets on cluster nodes.

kube-prometheus-stack

kube-prometheus-stack uses Prometheus-operator and Prometheus to provide easy-to-use, end-to-end Kubernetes cluster monitoring capabilities.

With this add-on, you can interconnect monitoring data with CIA to view monitoring data and configure alarms.
