Determine the additional cluster capabilities needed based on workload dependencies and operational goals, then install or maintain the corresponding components.
Components extend CKS clusters with storage, network, device, scheduling, training, and O&M capabilities. Do not install components in batches based solely on their names. First, determine which capabilities your workloads lack:
When workloads require network, persistent storage, GPU, RDMA, or node management capabilities, see the foundational capability components.
When you need to expose services, run batch or distributed training jobs, or orchestrate workflows, see the business runtime components.
When you need to collect metrics, logs, and events, or perform inspections, backups, and multi-cluster management, see the observability and operations components.
This set of components provides the cluster with container networking, persistent storage, node management, and device resources. If a workload depends on any of these capabilities, ensure that the corresponding component is installed first.
The device resource component registers GPU or RDMA devices as schedulable Kubernetes resources, enabling workloads to request and use the corresponding devices.
Component
Purpose
When to install
nvidia-device-plugin
Reports and allocates NVIDIA GPU device resources.
Required when requesting and using GPUs in Pods.
rdma-device-plugin
Reports and allocates shared RDMA NIC device resources.
Required when using RDMA network capabilities in workloads.
These components provide traffic entry points for services, run batch or distributed training jobs, and orchestrate and maintain application workflows.
This set of components is used to collect metrics, logs, and events; detect cluster anomalies; perform checks or backups; and manage multiple clusters.
The monitoring metrics component collects metrics from Kubernetes objects, nodes, storage, GPUs, CPUs, network hardware, the control plane, and high-availability components.
Component
Purpose
When to install
metrics-server
Collects Pod and node resource metrics.
When you need to view basic resource usage or use HPA capabilities that depend on resource metrics.
kube-state-metrics
Collects Kubernetes object status metrics.
When you need to monitor the status of Kubernetes objects such as Deployments, Pods, and Nodes.
node-exporter
Collects node system metrics.
When you need to view system metrics for nodes, such as CPU, memory, disks, and network.
gpfs-exporter
Collects GPFS storage metrics.
When you need to view GPFS file system capacity, performance, or operational status metrics.
dcgm-exporter
Collects GPU metrics.
When you need to monitor GPU utilization, GPU memory, temperature, and other GPU operating conditions.
pcm-exporter
Collects CPU PCM performance metrics.
When you need to analyze underlying performance data such as CPU performance or memory bandwidth.
ib-hca-exporter
Collects InfiniBand network adapter metrics.
When you need to monitor InfiniBand network status and performance.
ipmi-exporter
Collects out-of-band IPMI hardware metrics.
When you need to monitor server hardware health status.
haproxy-exporter
Collects control plane HAProxy metrics.
When you need to monitor the status of control plane proxy services.
keepalived-exporter
Collects VIP keepalived status metrics.
When you need to monitor the high-availability status of control plane or ingress VIPs.
vmo
Provides victoria-metrics-operator.
When you need to extend monitoring capabilities through the VictoriaMetrics ecosystem.
prometheus-monitoring-cks
Provides Prometheus capabilities for Kubernetes monitoring.
When you need to deploy Prometheus monitoring for CKS clusters.
After identifying the components required for the workload or O&M objective, proceed with installation. Installing multiple components with similar functions may increase resource consumption and maintenance complexity.
Click the target cluster name to access the cluster workspace.
In the left navigation pane, go to the Component page.
Click Install.
In the Install component dialog box, select a component.When the component list is long, enter a component name in the search box to filter the list.
After confirming that the component name and purpose meet business requirements, submit the installation.
Return to the Component page. After confirming that the component status is normal, deploy workloads that depend on this component.If a component is in an abnormal state, first verify that the cluster resources, namespace, storage, or network configuration it depends on are functioning properly. If the cause still cannot be identified, record the component name, version, namespace, and error message, and contact technical support.
Updating or deleting a component may affect business operations, monitoring, logs, storage, network, or O&M processes that depend on it. Before proceeding, confirm the component’s purpose, dependencies, and scope of impact.
On the Clusters page, click the name of the target cluster.
In the left navigation pane, go to the Component page.
Locate the target component and confirm its purpose, as well as the workloads or operational processes that depend on it.
Perform the following actions as needed:
Update a component: Click Update.
Delete a component: Click Delete and confirm as prompted.
After completing the operation, return to the Component page to verify the component status.
