Properties

Property Type Required Editable Description Constraint
Role String No Yes The type of nodes that you want to query. Valid values:
  • Manager: management node
  • Login: logon node
  • Compute: compute node
HostNameSuffix String No Yes The suffix of the hostname. You can query nodes that have the specified suffix.
PrivateIpAddress String No Yes The private IP address. None.
ClusterId String Yes Yes The ID of the cluster. You can call the ListClusters operation to query the cluster ID.
HostNamePrefix String No Yes The prefix of the hostname. None.
HostName String No Yes The hostname of the node. Limits:
  • Fuzzy match is supported.
  • MySQL regular expressions are supported.

Return values (Fn::GetAtt)

  • NodeIds: the IDs of nodes.
  • NodeIds: the list of nodes.
Property Type Description Constraint
NodeIds List The IDs of nodes. None.
Nodes List The list of nodes. None.
NodeId String The ID of the node. None.
ImageOwnerAlias String The type of the image. None.
StateInSched String The status of the node. The status of the node varies based on the scheduler type.
ZoneId String The ID of the zone. None.
VSwitchId String The ID of the vSwitch. None.
Expired Boolean Indicates whether the subscription node has expired. Valid values:
  • true: The subscription node has expired.
  • false: The subscription node has not expired.
AddTime String The time when the node was added to the cluster. The time follows the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time is displayed in UTC.
PublicIpAddress String The public IP address. None.
IpAddress String The IP address of the node. None.
VpcId String The ID of the virtual private cloud (VPC). None.
CreateMode String The mode in which the node was created. None.
Version String The version of the client. None.
UsedResources Map The total amount of resources that are used by the compute node. Sample code:
{
      "Gpu" : 0,
      "Cpu" : 0,
      "Memory" : 0
    }
TotalResources Map The total amount of resources that are used by the node. Sample code:
{
      "Gpu" : 0,
      "Cpu" : 1,
      "Memory" : 1024
ImageId String The ID of the image. None.
HtEnabled Boolean Indicates whether hyper-threading is enabled. Valid values:
  • true
  • false
RegionId String The ID of the region. None.
LockReason String The reason why the node is locked. Valid values:
  • financial: The node is locked due to overdue payments.
  • security: The node is locked due to security reasons.
  • recycling: The node is locked because the node is a preemptible node and waiting to be released.
  • dedicatedhostfinancial: The node is locked due to overdue payments of the dedicated host.
InstanceType String The instance type of the node. None.
HostName String The name of the node. None.
SpotStrategy String The bidding policy for the compute node. None.
Location String The location of the node. Valid values:
  • OnPremise: The node is deployed in your data center.
  • PublicCloud: The node is deployed in the Alibaba Cloud public cloud.
Roles List The type of the node. Valid values:
  • Scheduler: primary scheduler
  • SchedulerBackup: secondary scheduler
  • Account: primary domain server
  • AccountBackup: secondary domain server
  • Login: logon node
  • Compute: compute node
Note Schedulers and domain servers are management nodes.
