Specifies platform for instances in the node group.
--metadata key=value[,key=value...]

--metadata-from-file key=value[,key=value...]
Same as --metadata except that the value for the entry will be read from a local file.
--template-labels key=value[,key=value...]
List of platform (not Kubernetes) labels for Compute Cloud instances in the node group as key-value pairs.
No more than 32 per resource. The maximum string length in characters for each value is 128. The string length in characters for each key must be 1-63. Each key must match the regular expression '[a-z][-_./\@0-9a-z]*'.
--template-labels-from-file key=value[,key=value...]
Same as --template-labels except that the list of key-value pairs for the entry will be read from a local file.
--public-ip Set when node group needs external public IP.
--memory byteSize
Specifies how much memory instances should have.
--cores int
Specifies how many CPU cores instances should have.
--core-fraction int
Specifies baseline performance for a core in percent.
--gpus int
Specifies how many GPUs instances should have.
--preemptible Specifies if created nodes will be preemptible.
--gpu-cluster-id string
Specifies if created nodes will be part of the GPU cluster.
--gpu-environment string
Specifies GPU environment for created nodes. Values: 'runc-drivers-cuda', 'runc'
--disk-type string
Specifies boot disk type for instances, valid values: network-ssd|network-hdd
--disk-size byteSize
Specifies boot disk size for instances.
--fixed-size int
Specifies fixed scale policy size.
--auto-scale PROPERTY=VALUE[,PROPERTY=VALUE...]
Auto scale policy for Node Group.

Possible property names:
  • min: Minimum number of nodes in the node group.
  • max: Maximum number of nodes in the node group.
  • initial: Initial number of nodes in the node group.
--location PROPERTY=VALUE[,PROPERTY=VALUE...]
List of node group locations.

Possible property names:
  • subnet-id: Subnet id.
  • subnet-name: Subnet name.
  • zone: Zone of the subnet.
--version string
Node Kubernetes components version. Default depends on Cluster release channel. See available in 'yc managed-kubernetes list-versions'.
--allowed-unsafe-sysctls value[,value]
List of strings containing allowed unsafe sysctls for use on nodes.
--node-labels key=value[,key=value...]
Kubernetes labels that are assigned to the nodes of the node group.
--node-taints value[,value]
Kubernetes taints that are applied to the nodes of the node group.
--auto-upgrade Sets auto upgrade maintenance policy. 'true' by default.
Policy defines if Node Group can be upgraded to newer version revision in specified maintenance window.
Auto upgrade is 'graceful': new nodes are created, while old nodes drained by one. Please setup Pod Disruption Budget, for graceful pods drain.
For details about PDB see https://kubernetes.io/docs/tasks/run-application/configure-pdb/
New revision contains can contain bug and security fixes, so it's recommended to leave this policy enabled. Node Group never upgraded to another major version automatically, even with this policy set to true.
Examples: '--auto-upgrade=false', '--auto-upgrade'
--auto-repair Sets auto repair maintenance policy. 'true' by default.
Policy defines if nodes seems to be broken can be recreated automatically.
Examples: '--auto-repair=false', '--auto-repair'
--anytime-maintenance-window Allow maintenance anytime. This is default maintenance window.
--daily-maintenance-window PROPERTY=VALUE[,PROPERTY=VALUE...]
Allow maintenance everyday specified days of week in the specified time window.

Flag can be used multiple times, to define different time windows for different days of week.

Examples:

--daily-maintenance-window 'start=22:00,duration=10h

Possible property names:
  • start: Time of day in UTC time zone, HH:MM 24-hour clock format, since when maintenance operations are allowed. Example: '02:30'
  • duration: Maintenance window duration in interval [1h; 24h]. Example: '12h30m'
--weekly-maintenance-window PROPERTY=VALUE[,PROPERTY=VALUE...]
Allow maintenance on specified days of week in the specified time window.
