gsctl list nodepools
gsctl list nodepools command lists all node pools of a cluster.
Execute the command with the cluster ID as the only argument. Example:
gsctl list nodepools 3if4
You can also use the cluster’s name for identifying the cluster:
gsctl list nodepools "Cluster name"
The result will be a table of all node pools of a specific cluster with the following details in columns:
ID: Node pool identifier (unique within the cluster)
NAME: Name specified for the node pool, usually indicating the purpose
AZ: Availability zone letters used by the node pool, separated by comma
INSTANCE TYPE: EC2 instance type used for worker nodes
ALIKE: Whether similar instance types are used within this node pool (e. g. if
m5.xlargeis defined also
ON-DEMAND-BASE: Number of on-demand instances that this node pool needs to have until spot instances are used
SPOT-PERCENTAGE: Percentage of spot instances used once the on-demand base capacity is fulfilled. A number of 40 would mean that 40% will be spot and 60% will be on-demand instances.
NODES MIN/MAX: The minimum and maximum number of worker nodes in this pool
NODES DESIRED: Current desired number of nodes as determined by the autoscaler
NODES READY: Number of nodes that are in the Ready state in kubernetes
SPOT INSTANCES: Number of nodes using spot instances
CPUS: Sum of CPU cores in nodes that are in state Ready
RAM (GB): Sum of memory in GB of all nodes that are in state Ready
-o: Using this flag with the value
json, the output can be printed in JSON format. This is convenient for use in automation. The default output format is
