Inspect a node

To view details of an individual node in your cluster, from the menu expand Cluster and select Details, then scroll down and click on the name of the node you want to inspect.

Information about the cluster is separated into three screen tabs: Node, Events, and YAML. An Applications running on this node section remains at the bottom of the page.

Node

The Node tab summarizes the following information about the selected node:

Field/Option
Overview

Hostname

The hostname of the node.

Kubernetes API

The address and port of the Kubernetes API for this node.

Role

The role of the node.

Kubelet version

The version of kubelet on the node.

Creation date

The date when this node was created.

Status

The status of the node.

Availability

Defines the availability of the node. Options are Active, Pause and Drain.

Resource reservation

This section provides details about resource reservations assigned on the node as well as the node's resource usage.

Memory used and CPU used are only displayed if you have enabled using the metrics API.

Labels

This section lists the labels that apply to the node. You can add additional labels if required, as well as edit non-system labels.

Taints

In this section you can add taints to prevent certain pods being deployed on the node.

Events

This section shows information about node-related events.

YAML

Editing the YAML in this view is only available in Portainer Business Edition.

This section shows the node YAML within an editor. To apply any changes you make within the YAML editor, select the Apply changes button, and select Apply changes if you are sure. Changes are made by calling the Kubernetes API to patch the relevant resources. Any resource removals or unexpected resource additions that you make in the YAML will be ignored. Note that editing is disabled for resources in namespaces marked as system.


Applications running on this node

This section provides information about the applications running on the selected node. Clicking the application name will take you to the application details page for that application.
