HTTP request

GET /kubernetes/{cluster}/api/v1/nodes/{name}

read the specified Node

Path parameters

Name Type Required Description
name string Truename of the Node

Query parameters

Name Type Required Description
exact boolean FalseShould the export be exact. Exact export maintains cluster-specific fields like 'Namespace'. Deprecated. Planned for removal in 1.18.
export boolean FalseShould this value be exported. Export strips fields that a user can not specify. Deprecated. Planned for removal in 1.18.
pretty string FalseIf 'true', then the output is pretty printed.

Parameters

Name Type Description
apiVersion string See common parameters
kind string See common parameters
metadata object See common parameters
spec object NodeSpec describes the attributes that a node is created with.
Path: spec
spec.podCIDR string PodCIDR represents the pod IP range assigned to the node.
Path: spec.podCIDR
spec.podCIDRs array podCIDRs represents the IP ranges assigned to the node for usage by Pods on that node. If this field is specified, the 0th entry must match the podCIDR field. It may contain at most 1 value for each of IPv4 and IPv6.
Path: spec.podCIDRs
spec.podCIDRs[] string
Path: spec.podCIDRs[]
status object NodeStatus is information about the current status of a node.
Path: status
status.addresses array List of addresses reachable to the node. Queried from cloud provider, if available. More info: https://kubernetes.io/docs/concepts/nodes/node/#addresses Note: This field is declared as mergeable, but the merge key is not sufficiently unique, which can cause data corruption when it is merged. Callers should instead use a full-replacement patch. See http://pr.k8s.io/79391 for an example.
Path: status.addresses
status.addresses[] object NodeAddress contains information for the node's address.
Path: status.addresses[]
addresses[].address string The node address.

Path: status.addresses[].type
status.allocatable object Allocatable represents the resources of a node that are available for scheduling. Defaults to Capacity.
Path: status.allocatable
status.capacity object Capacity represents the total resources of a node. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#capacity
Path: status.capacity
status.conditions array Conditions is an array of current observed node conditions. More info: https://kubernetes.io/docs/concepts/nodes/node/#condition
Path: status.conditions
status.conditions[] object NodeCondition contains condition information for a node.
Path: status.conditions[]
conditions[].lastHeartbeatTime string (date-time) Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
Path: status.conditions[].lastHeartbeatTime
conditions[].lastTransitionTime string (date-time) Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
Path: status.conditions[].lastTransitionTime
conditions[].message string Human readable message indicating details about last transition.
Path: status.conditions[].message
conditions[].reason string (brief) reason for the condition's last transition.
Path: status.conditions[].reason
conditions[].status string Status of the condition, one of True, False, Unknown.
Path: status.conditions[].status
conditions[].type string Type of node condition.
Path: status.conditions[].type
status.daemonEndpoints object NodeDaemonEndpoints lists ports opened by daemons running on the Node.
Path: status.daemonEndpoints
daemonEndpoints.kubeletEndpoint object DaemonEndpoint contains information about a single Daemon endpoint.
Path: status.daemonEndpoints.kubeletEndpoint
